Creating the Perfect Rat Set-Up


A Rat's Poem

I live in a pet store.

In my bedding of fleece

Spend my day behind glass

Where I’m tapped at and teased

I take my food in rations

And my water from pipes

I run the wheel with passion

But mostly at night.

Do I sound cute?

Well how do you like that?

Who knew you would root,

For the average brown rat!

Yep, my name is RAT

But you say it like a cuss

Hey, I am what I am

And I do what I must!

We make humans squirm

They think of the street.

With our tails like worms

And our clawed little feet

But don’t call us vermin

Just because we’re superfluous

Streets are packed with your kin

At least we serve a purpose!

I am rattus norvegicus

Clean and intelligent

A good pet for children

Gentle ones, that is!

I wouldn’t bite you

Like that hamster you trust!

Hamsters carry rabies too, you know!

Alas, but they too, do what they must.

People see us and grimace

“Gross! Look at the RATS!

They are so ugly!

Who would want THAT?”

And although they moan and they fuss

We are what we are

And we do what we must

So hey, before you snub me

For being my breed

Ask questions about me

And find books to read

Many people love us

And will gladly discuss

How rats are fantastic,

Though they do what they must!




I’ve worked as a pet care consultant for over six years, and I can tell you that rats have never been the most popular animals in the store. An example of the average conversation between me and a customer would sound a little something like this:

“Oh my God, are those rats?”


“That’s disgusting! Who would want rats as pets?!”

“They make wonderful pets.”

“You must be INSANE!”

That’s a good dose of daily ignorance that I come across during my work hours. People will venture into the pet store looking for a new addition to the family and find their way to my side, the small animal department. At first, everyone notices the rabbits and only the rabbits, but when it becomes apparent that rabbits need more than just food and water every day, they begin to look for less demanding pets. As they meander about, they come across the small rodent section and stop cold. A cringe breaks the corners of their mouths at the sight of playful baby rats scampering about their cage. Gross! In the next moment, they find themselves swooning over the adorable dwarf hamsters that paw and nip at fingers venturing too close to the bars of the cages. Does it make sense? No. Will it ever change? Probably not. But for those who would wish to set aside their stereotypical view of the common sewer rat crawling up out of the toilet and eating the baby, here is a detailed professional care sheet on the pet rat, also called the Fancy Rat.

Why People Shouldn't Hate Rats

Contrary to popular belief, rats are not the swarming vicious rodents of movies like Ben and Willard. I was very pleased when Disney’s Ratatouille came out, because for once these poor little critters were not the hunch-backed, red-eyed villains of most other cartoons and movies featuring rats.

A wild rat is no more thrilled to see you than you are to see it. Rats only live near people because we leave out such darn tasty garbage and live in great places to nest. The fact is that wild rats do what they can to survive, as my poem tries to illustrate. They only become a problem to humans when we offer them the proper surroundings. The Black Plague we all read about was spread by way of the flea, which can also latch onto our cuddly cats and dogs. The plague epidemic has ended by the way, and oh yeah, WE HAVE PENACILLAN NOW!

Rabies is a big concern I’ve noticed a lot of customers have when they question me about rats. I find this utterly ridiculous, since pet store animals have not and probably never will make contact with wild animals. Rabies cannot be born into an animal, nor can an animal or person catch rabies without being bitten or scratched by an animal already afflicted with the disease. I cannot believe more people don’t already know this. I remember one time, one of our pet store rats bit someone who poked at it through the cage bars and irritated it. The person freaked out and demanded we send the animal away for rabies testing, and if you don’t already know this, rabies testing involves killing and decapitating the suspected animal. What a waste and what a shame. I can bet you any amount of money that if a rabbit had bitten the guy, he would have chuckled and walked off, no rabies testing asked for.

So after reading my little rant, how do you feel about rats now? Still disgusted? Then you might as well click off this page and look up something on guinea pigs. I am never going to get through to you. If you’re finding yourself more interested in keeping pet rats, read on, because I have got the perfect set of instructions for you.

Getting the Right Cage

Keeping rats is a big responsibility that is not to be taken lightly. A rat is a living thing that depends on you for its food, water, hygiene, warmth, and security. For the two or three years you will have your little buddy, you essentially control his livelihood, so do not jump into rat ownership on a whim, because guess who will suffer for it? Your pet.

The first thing I recommend doing before heading for the pet store you’ve already started to do: Research. Reading about your new pet before you get him is crucial so that you will not end up jumping into something you are not ready for. Though I am an experienced rat keeper, I strongly suggest that after reading my article, you go out and purchase a book on rats to really dive into what keeping rats is really all about. My information will get you started, but there is a whole range of information that I simply can’t cover here that you ought to know, so start researching!

The second thing you need to do before bringing home the rat is to purchase the cage, and there are many styles to choose from. Some people will say that keeping rats in aquariums works well and they have never had a problem with it, but I have a problem with it and I’ll tell you why. For one thing, aquariums are designed for fish, which do a whole lot of swimming back and forth and nothing else. Rats are energetic and love to explore, so narrow fish tanks are not going to offer them the climbing and running space they need to live a fulfilling life. Even a huge fish tank will not do the trick and it will be expensive anyway. Also, fish tanks can create humid, germy environments that can eventually lead to respiratory problems in small lunged animals like rats. It is very hard to clean a heavy aquarium properly and really get into the corners to clean out the gunk and sanitize it. Bacteria will build up and not only make it smell horrible, but create a very unsafe environment for your rats. I suggest using a wire cage, preferably powder coated, with bars that are spaced no more than an inch and a half apart. If possible, get a cage that is constructed with both horizontal and vertical bars so that it eliminates the chances of a baby rat getting stuck or escaping. A rat can escape through any hole it can get its head through, so don’t tempt him! Also, barred wire cages provide a lot more space for your rat to climb, give you places to clip on toys and hammocks, and provide ventilation to promote good health. If you have a closed up aquarium, even if it has a mesh top, your rat is going to be spending a lot of his time breathing in his own poop. Gross! Get a wire cage.

Now, sizing is another big step in cage selection. I suggest a multi-leveled home that is at least as tall as it is wide with ramps and shelves. Depending on how many rats you intend on keeping, you may end up having to go with a good sized ferret style cage rather than one intended for rodents. I suggest keeping a single pair of rats in a cage with at least two shelves that is no smaller than 2 x 2 x 2, but bigger is always better!

Decorating and Maintaining the Cage

Once you purchase the cage, you have to think about filling it with the essentials, bedding, furniture, and toys. Yes, I said toys. Rats are extremely intelligent, and like most pets (and kids!), will get lazy and fat if not stimulated to play with interesting toys. You can use a variety of toys found in pet stores. Rats should always have a hanging ferret bed in their cage. It gives them a nice comfy spot to hide and sleep. They should also have at least one wooden hide out per rat in different areas of the cage to provide privacy and security. Rats also love to chew! Wooden hamster blocks, and chew sticks are great for this habit, but don’t limit yourself to the rodent section of the pet store. Some of my rats favorite toys were not even designed for them! Cat balls with bells in them can be lots of fun, as can hanging bird toys with different textured wood and rawhide. Stay away from toys that have small parts like beads, or your rat could choke on them. I also love to give my rats tissues boxes, toilet paper tubes, old clean socks, shirts, and any other “clean garbage” I have laying around. Never give your rats thin plastic or anything treated with lacquer, perfume, glass or tile cleaner, or oil. Use common sense. If it is safe for a toddler, it’s probably safe for your rats too.

Of course, you’ve got to feed and water your rats! Choose a plastic water bottle available in almost all pet stores, preferably a clear one so you can see how low the water level is. Do not get a glass bottle as these are easily shattered. Always attach the bottle to the OUTSIDE of the cage or the rats will chew it apart in hours. Make sure the metal tube with the ball inside it is drip proof and easy to access through the bars. Your rat will drink from it by moving the metal ball with his tongue, so make sure you do not get an oversized bottle with a ball too heavy for him to move. I find a 16 oz. bottle very appropriate for both baby and adult rats. A 32 oz. will probably work too, but it won’t deplete as quickly. Sounds like that would be a good thing right? The reason I say it isn’t is because rats do not go through water very quickly and it will end up stagnating in the bottle and algae will build up. A 16 oz. bottle will keep two rats watered for about two days, and then you should rinse it out and refill it. You will also want a small to medium sized ceramic food crock designed for small animals. Always place the crock away from the edges of shelves so it does not fall down and crush one of your pets! Make sure it is not situated directly below the water bottle or else water will drip down and spoil the food. Keep an eye on the food level and fill it when it is more than halfway empty. Check around the cage though. Rats love to hide their food so they may have more food left than you think! You do not want to waste food.

Sanitize the water bottle as well as toys and food dishes once a week with a teaspoon of bleach mixed in with about two cups of water. You can use a bottle brush to scrub out the inside of the bottle. Wash the little metal sippy part too! You also probably want to use this time to wipe down the cage tray with a Clorox wipe or a soapy rag. I santize the furnature and tray once a week for my single rat but if you have more than one per cage, you may want to do it two or three times. Also, every two weeks or so, give the wire a good misting with cleaning solution, let it sit for about ten minutes, and rinse it VERY WELL with hot water. Dry everything before it goes back to your rats.

Bedding and Food


Okay, so you’ve gotten all of the furniture situated in your cage, now you’ve got to think about bedding and food. This is where the debate thickens, as everyone has their own preferred food and bedding. I will level with you. There is no perfect food or bedding. Some things work for some rat owners better than others. Some rats are more sensitive to dust or allergens than others. Some rats are pickier than others. Your adventures with your rat’s well being will continue all through his life, and you will learn new things all the time. I know I still do. Over the course of each of my rats’ lives I have found out what brands of food and bedding have worked best for them, but please remember that there are variants with every rat and a veterinarian experienced with rats will be the best person to talk to if you are concerned.


Generally, I don’t like to use wood based beddings in ANY small animal’s cage because of the dust and oil involved. Cedar bedding (big reddish and brown chips) smells nice, but makes a better potpourri than a pet bedding. Animals have been known to get severe respiratory infections from cedar, and the large pieces can be eaten and create intestinal blockages. I learned this the hard way when I was a kid with my guinea pig, Pepper. Pepper stopped eating and drinking, so we took him to the vet and found out he was suffering from intestinal inflammation. It was causing him to get bloody diarrhea and he became very dehydrated. Though we treated him with an antibiotic and force fed him water through a dropper, I still lost him to cedar bedding. Stay away from it.


Pine shavings (yellowish in color) are probably the most popular bedding for small animal keepers because it is cheap and easy to find. A lot of animals do well on it, though it can still cause respiratory infections and can be very dusty depending on how thinly cut the pieces are. Rats are very sensitive so it is best not to use pine in their cage. I am an asthmatic, so I think about these things when I am buying bedding. If it’s dusty and it makes ME sneeze just from cleaning the cage, think about how the poor rats must feel living in the stuff!


Aspen (stringy yellow pieces) is probably the best wood based bedding to use if you are going to opt for wood based beddings, which I don’t. It has the lowest amount of dust of all the wood beddings and its long stringy pieces create nice nesting material. Personally, I hate the smell of it. It makes me sneeze and my asthma acts up, so I am not much into aspen. Some rats can also be allergic to it, so watch for problems if you choose aspen.


My preferred beddings are the brands Carefresh and Boxo. Carefresh is made out of recycled paper material and Boxo is made from shredded cardboard boxes. Both of these beddings are a little bit dusty, but it has never made me sneeze and my rats do great on it. I tend toward Boxo more often lately since Carefresh is cut into larger pieces and is a little more expensive. Boxo is more finely shredded and packs down easier, saving more space and money. You can get a huge bag of about 102 dry quarts of Boxo for around thirty dollars. Regardless of which bedding you choose, always keep an eye on your rats and make sure they are not sneezing an abnormal amount, getting reddish mucus around their eyes and nose, scratching or biting themselves, getting red welts or scabs, or losing fur. Any of these symptoms could be a sign of allergies, so change the bedding and see if it improves. If not, your rat may be sick. Take it to the vet right away.


When it comes to food, most experienced rat keepers can agree that seed mixes intended for hamsters or mice are a No-No. Rats are like children with marshmallow cereal, and will pick out the junkiest part of the mix and leave the healthier bits. They will get fat on seeds and will not be as healthy as rats kept on commercial rodent blocks, also called laboratory blocks. My favorite brand is Forti-Diet Rat & Mouse, a bland rodent block designed for all rodents. All of the hamsters, rats, mice, and gerbils I’ve kept have been on this food exclusively and stayed trim and fit with nice shiny coats. There are other brands of lab blocks available and some people will argue back and forth about the protein levels in each one and how much protein is too much. I like to keep the protein levels between 11-18 percent. If you are offering your rat daily treats of fresh green veggies, and occasional treats of dry pasta, grain based cereal, and a little bit of kitten kibble, your rat will get plenty of variety and will do great on a base diet of blocks. DO NOT OVERDO IT ON THE TREATS! A little bit does not mean a human sized handful! Look at the size of your rat’s head and feed him a piece half the size of that. Think about this, a single Cheerio in a rat’s paws is the equivalent in portion to a whole sized doughnut in ours! When it comes to veggies, a half leaf of red romaine or a sliver of green pepper is enough. Do not give your rats a lot of fruit. It can cause obesity and diarrhea. Once a month or so, half a grape per rat is plenty!

How Many Rats?

Now you’ve got it all! You have a large multi-leveled wire cage big enough for two rats with plenty of toys and hiding spots, a ferret bed, a full food dish and water bottle, and some nice soft bedding. Now all you have to do is add the rats! Happy day!

I always say two is better than one when it comes to small animals. Rats especially are social creatures that do best in the company of other rats. I’ve been asked if having two or more rats will reduce the chances of a rat bonding to its owner. The answer to this is no. Rats feel more secure when they have a friend, and so are less threatened by the much larger human moving around their cage. They will huddle together for warmth, groom each other, wrestle and chase each other, and keep each other occupied when there is no human around to let them out. In groups of two I have noticed that one rat does seem to usually be friendlier with people than the other. There is always one that is a little more skittish and apt to hide while the other may jump up on the cage bars begging to be let out. This is not always the case, but the reason for this is that one rat always has to be dominate and the other submissive. The submissive rat is more likely to be the one hiding, since he is waiting for the dominate rat to check things out first. This doesn’t mean that he will be mean or scared of you; it is just a natural way rats react to new things. Give your rats a few weeks to get used to you, and both should be sticking their noses through the bars begging for your attention.

Boys or Girls?

When it comes to male versus female, it is all a matter of opinion. While males do tend to urinate to mark their territories more often than females (and you can neuter him to eliminate this behavior), they do not stink any more than females. All animals stink if you do not clean the cages, and rats are no exception. I find males have a stronger body odor but not excessively so. You only notice it if you are sticking your nose in the rat’s fur! Male rats also are larger than females and tend to be less active. A happy male may be content to perch up on his shelf and observe the activities of his humans all day while the female in the cage next door is busy building a nest or running on her wheel. Males also seem to sit still longer when you are holding them. Female rats are usually a bit smaller and have a narrower snout than the male, and as a rule are more interactive with their owners. Both male and female rats are loving and affectionate and will lick their owners and make pleasant chattering sounds when happy. Both males and females can be trained to a certain spot to potty, perch on their owner’s shoulder, and respond to their names. Rats can be let out of their cages to run free for a few hours a day as long as cats and dogs are locked out of the room, cords are lifted out of the way, and chewable temptations are removed. Unlike hamsters, rats will not disappear never to return. They like the security of their cages and will eventually go back to them if the cage is left on the floor with the door open. Never chase your rats or corner them, or they will not want to come out of hiding. I let my rats out every day while I am on my computer and will often times feel them climb onto my foot and wait to be picked up and cuddled. Do not use runabout balls. Balls are CRUEL! The rat is basically trapped in a bubble and cannot go anywhere or do anything. Rats of both sexes are very intelligent, so make sure you utilize this intelligence and give your rats plenty of attention and free time outside of their cage to stimulate their small, but very versatile minds.

Thinking of breeding? DON'T! There are a lot of problems with genetic faults in fancy rats as a result of inbreeding. Rats can develop tumors, be prone to disease, and live shorter lives if they were not bred properly. Not to mention there is already a pet overpopulation issue and breeding your pets just for the fun of it just makes things worse. Think about the welfare of the parents. Breeding takes a lot of energy out of a female rat, and both sexes become very aggressive when there are babies in the cage to protect. Think about the babies. Rats can have litters as small as 3 and as big as 20. They will need homes, and not many people are just going to be willing to take them off your hands. Pet stores are already overrun with unwanted baby rats. Breeding should be handled by professonals. If you must have a male and female rat, get one or both of them fixed. I had a fixed male and female together for years without any problems.

Final Thoughts


Everything you’ve just read is from my own personal experience. Talk to several rat owners and find out what it’s like to have them. Hop online and check out articles and pet care websites, or go to the library and pick out a few good books. There is a lot more out there to learn and you should have fun doing it! Always have a vet’s number available and remember to pay attention to the signs and you and your rat should live a long happy life together. Happy rat ownership!

Nice hub. I think you've done a really good job of covering all the rattie basics.

No no noo! The last picture with the ratties on the wire floor is a big no! Rats should never have wire flooring like that. It can give them sores on their little feet! It is extremely not safe for them and should never be used.

Jess 5 years ago

I have always used wire cages and never had a problem. The wire is powder coated and it is only on the shelves. The bottom of the cage is flat and plastic. My rats have never had foot issues.

Raven 4 years ago

Wire floors are not proven to be the cause of bumble foot, and as long as they have soft spots(like that bed), the base is hard plastic (like she said), and overall the cage is kept clean, there should be no problems. If you are really worried about it though, you can always put wood or sturdy fabric over the wire platforms to keep them from walking directly on it.

To the author of this page: You might want to consider pulling back a bit on the 'tude. I have faced my share of "rat discrimination," but this isn't the way to win them over. People (rat-loving people, to boot) come to this page for information on proper care and environmental enrichment, not a ranting diatribe. If a non-rat-lover stumbles to here by accident, their opinion on rats isn't going to be changed by your insults.

Tiffany 2 years ago

the two things I disagree with - you didn't mention fleece as bedding, and glass water bottles are MORE sanitary than plastic ones and last a heck of a lot longer I've been using glass for years!

Rachel 2 years ago

Thank-you for your post! Rats are wonderful, sweet, affectionate pets. I also can't help but be dismayed by the ignorant people that tell me my rats are gross. They must not realize that people carry way more diseases than any pet rat!-thanks again:)

This says the bars on a wire cage should be no more than "an inch and a half" apart. This is WAY too far apart! A fully grown rat could easily get through that. I wouldn't go more than half an inch. A cage designed for a ferret or rabbit likely has the bars too far apart for rats, just as a cage for a hamster is likely way too cramped.

I would also suggest a glass bottle, plastic has so many chemicals in it. Plus how is it going to get shattered?? Refill with new water every day and thoroughly wash the bottles/bowls/etc. at least once a week. I would NEVER use bleach because it is so toxic, you can't always know that you definitely got all of it off. I use hot water for light cleaning and a natural, gentle dish soap for more thorough cleaning. Unless you have some sort of virus spreading through your rats, there is no need to use bleach or anything strong like that.

Just don't use any kind of wood bedding, period. Rats have VERY sensitive respiratory systems. In fact, many rat owners don't use any kind of bedding as even the paper/cardboard stuff like CareFresh can be a problem. I personally put a towel down on the plastic tray bottom, making sure it goes over the edges so that the top metal part will hold it in place. This is better for their little lungs, easy to clean, prevents them from chewing on the plastic tray (unless they chew through the towel, obviously), and prevents any bedding from being kicked out of the cage. I also think it's fun to be able to swap out colors. I use paper pellet cat litter in the litter box (no clay or fragrances). Sometimes I will put some CareFresh in their little igloo when it's cooler, but they also like to nest in bits of fabric or washcloths.

Half a grape per rat once a month is a little extreme. I do strongly agree with:

AT LEAST TWO RATS, never just one.

DO NOT breed them, make sure you keep the sexes separate at all times.

Some One Who Loves Rats 14 months ago

Someone said to always have two rats, never one? I disagree. Having more than one rat makes them bond more with each other than with you, plus twice the mess :). Having one makes him/her bond more with you. Now, if you have only one rat, you should take him/her out at least everyday. I take mine out 2 or 3 times a day for at least 15 minutes. It is very important to get them used to there surroundings, inside and outside of their cage.

Great hub overal. Didn't agree with anything you said in particular. Just got two new rats today (boys): Solo and Ewok.

I have been round rats all my life,

I agree the bottom of a wire cage can be cruel I use paper on the bottom so they walk on solid ground =)

my two rats are ozzzy and annie =D

Rhiannon 2 months ago

I agree with one thing and that would be NEVER KEEP ONE RAT ALWAYS TWO! I recently got my first every rat and, I thought that if I only got one it would bond with me not another rat. But lupin quickly became depressed, and lonely no matter how much attention and entertainment I provided. And in the end he died from stress related issues, most likely caused by his loneliness. I would advise getting two or more happy and healthy rats, and if they were more attached to each other than I, I wouldn't care as long as they are happy and healthy.
