The Best Pet Lizard

If you are among the millions who climb into bed every night dreaming of the best pet, I have the answer you have been looking for. I have owned iguanas, monitors, many other species of smaller lizards, and I currently own about 20 or 30 geckos. (It is hard to keep count since they run free in my kitchen.)

None of them are “the best”. I have found the best, the perfect pet lizard.

The best pet lizard is the Tegu.

Actually, I keep several of these great pets around my house. My oldest, however, lives in my front room. His cage rests on the floor and when I am eating my breakfast I flip it open so that he can crawl out and lie in the sun with my dogs. When he gets bored (or maybe just warm-he has never told me which) he goes back to his cage and checks his dish to find out what is for his breakfast.

Tegus are big, mellow, affectionate, easy to care for, and with a good diet can live about 20 years.

Can there be a better pet?

Is The Tegu As Tame As A Dog?

No, Tegus are never as tame as a dog, despite some claims. They are the one of the most intelligent of reptiles, and even seem to be interested in humans, at times. Tegus do resist training, though, just like a cat.

They can be as tame as a cat in several other ways.

According to the animal behaviorist Patricia McConnell, one of the big differences between dogs and cats is the way they treat food. If a dog does not have enough, she will feed her puppies (or other dogs in the pack) and go hungry. A cat will take care of her own needs first.

Tegus are like cats in that they always think of number one. They like to eat, do not care too much about what is in their bowl, and do not really care who is doing the feeding.

Yes, many of those Tegus do like kids.

Feeding A Tegu

One of the common complaints about keeping exotic pets is how difficult it is to feed them. Dogs and cats can be fed just by going out and buying food from the pet store. What about a Tegu?

A lot of sites will recommend that the Tegu diet be composed of canned cat food, ground turkey, eggs, and calcium and vitamin supplements.

That diet is okay for a Monitor lizard, but not really needed for a Tegu.

A study of what wild Tegus eat showed that about 2/3 of their stomach contents was actually plants and only a third made up of things like snails, crabs, and other small animals. This makes sense, as in the wild Tegus can usually be found at the base of fruit trees, picking up the fruit that has fallen, and looking underneath for worms or other bugs that they might find.

Here are some suggestions for what you can feed your Tegu. Do not worry if you get things a little wrong. Tegus are forgiving, and not likely to develop nutritional diseases like Iguanas and some other lizards. If you feed your Tegu correctly, he may grow a little slower than those on a potent, high-protein, Monitor-type diet. He might also live longer.

Feeding a Tegu

Meat, only about 1/3
Vegetables
Fruit
Eggs
Squash
Figs
Ground Turkey
Zucchini
Grapes
Canned Cat Food
Peas
Bananas
Worms
Green Beans
Strawberries
Fresh Fish
Pumpkin
Cherries
Fresh Seafood
Greens (turnip, collard, etc)
Tropical (papaya, coconut, guava, etc)
If your Tegu has been spoiled by a meat diet, and is relucant to eat veggies,you can make a small plate each feeding and cover it with a raw egg.

Life With A Tegu

My Tegu does wear a collar (around his waist, not his neck) and I leave it on him all of the time. I only put his leash on when he is strolling around the house or outside in the front yard. The leash is not really necessary in the house, since if he climbs under my bookshelf or bed my dog will tell me where he is at (if I ask nicely), but with the leash on I can keep an eye on him if he crawls into a hiding spot.

When he climbs back into his cage I take the leash off.

Some mornings I will take him out and let him wander around my garden when I am working. I leave his leash on and tie him to a banana tree so that he´ll have some shade. He likes this since he can be out in the sun but still hide if he wants.

He does not care for the beach where it is open and he does not have somewhere to hide. In this he is very much like a cat—have you ever seen anyone take their cat to the beach?

What Are You Waiting For?

Are there bad things about sharing your house with a Tegu?

  • If you do not handle your Tegu they can become aggressive. They have teeth that will slice through flesh and wild Tegus are responsible for a lot of the dogs in our area walking around with hunks missing from their noses.
  • They need a large enclosure, or at least a decent sized cage and plenty of opportunities to get out and walk around.
  • My geese do not like him. I think it may be because of his long tail, or maybe it is that tongue flicking out every once in a while. I guess they think he looks like a snake and when he sits in the doorway they will not even try to go outside.
  • Tegus are not like a dog or cat in that they cannot be trusted with small animals. If you have a hamster, gerbil, or other small animal it must always be caged when your Tegu is strolling around the house. My parrot can handle himself in a fight but he always treads carefully when the Tegu is running around the house.

But is a Tegu the best lizard to share a house with? Definitely.

Is there anything I regret about having one of these pets? I just regret not getting a Tegu sooner. I have worked around Tegus since the mid-1970s but always thought there was another type of lizard or snake that would fit my family even better.

I was wrong. Tegus are the best pet lizard!

      This was an interesting read Dr Mark. I'm a reptile lover my self, have a Burmese Python and a Horned Lizard. I've seen a couple of animal shows on Tegu's in Miami and they are portrayed as being very aggressive and will bite off fingers. Guess I should do a little more research on them.

      Tegus should not be kept as pets in warm climates 3 weeks ago

      When they escape out into the wild, they breed and become invasive species. See: Florida.

      My son has a black and white tegu he got at a trade show over a year ago that was almost full grown. He keeps it in his room in a 6 by 3 foot cage. The smell is overwhelming when I open the door. I am constantly on him about cleaning the cage. It must be unhealthy to live with that smell in the room. To make matters worse he tells me he has a hard time handling it because it is so aggressive. I'm almost at the point of forcing him to give it up. Is there anything that can be done at this point to calm the tegu down so he can handle and enjoy having it and not be afraid of it every time he opens the door to feed it? The smell is the biggest concern for me and if there is a health hazard for my son in sharing a room with it. Is it a bad idea to keep it in his room? Even with the smell and not being able to handle it my son is adamant about keeping the lizard.

      Ethan, as long as you have plenty of wood shavings or leaves he will dig down and feel secure and happy. A normal cage will do for that.

      I am not sure if there are any laws against Tegus in Canada, but I doubt it. As far as him doing well in your house, as long as he has supplemental heat he will do fine there.

      Hi I was wondering if you meant he actually had to be able to go down/dig in his cage and I was also wondering if it is discouraged to own one of these in southern canada

      Hi jk1987 the size really depends on how often you are going to let him out to run. An adult needs at least a meter wide, a meter deep, and about 1.5 length, but you can get by with a cage that small only if it is open and your Tegu gets out to exercise. Most of the enlcosures recommended are larger, so even if you get a baby remember that these guys get really big, and if you do not have the space a small lizard is better.

      I live in the tropics so do not worry about humidity, but if you are in a drier region you need to get a humidity guage and keep the cage at about 80% humidity. The bedding needs to be sprayed to stay moist, and Tegus like to get in the water when they can (just like Iguanas and Basilisks).

      Hi Justin,

      Calcium supplementation can be dangerous. If you are giving calcium supplement make sure it is only sprinkled onto his food. What kind of diet is he on? If he is on a good Tegu diet, and is eating whole food like mice, newly hatched chicks, and guppies or other small tropical fish, calcium supplementation is not needed. In any case, it should not be more than 1% of his diet.

      We humans are likely to give too much, not too little, and if you give too much calcium supplement he is likely to have kidney stones and hardening (calcification) of his internal organs. Sometimes it can cause constipation also.

      Does he have a sunny spot he can sit in when he does come out? I hope you have changed his diet so he can heal naturally. Good luck.

      Hi, ive recently adopted a rescued argentian black and white tegu. His feet have grown weird due to a calcium deficiency and he obviously hasnt been handled much. Im giving him calcium powder daily and calcium/d3 supplement 2x weekly. Would you have any advice on nursing him back to health?

      Hes a little skiddish in his enclosure but once hes out and about hes a sweet heart. Hes already part of the family and i want to get him back healthy. Thanks!

      Steven, not sure what you meant about height. As far as width, it does not need to be much as long as he can get out and walk around your room. Leave the cage open all the time with plenty of wood shavings as bedding and when he feels the need he can just go in there, burrow down, and escape from it all.

      These guys are a lot easier and cheaper to feed than a snake. You can buy a dozen eggs and feed him cheaply, mix it up with some fruit, veggies, and a cheap canned cat food. The cheaper the better since there are more fillers!

      Have fun.

      I have a small room and my parents are divorced if i could fit a 8 by 2 by 2 cage in there and let it free roam in my room would that be okay? Also what is the best cheapest diet for these guys because i have 3 snakes and 2 dogs so the food prices are a little high

      To ??, I deleted your comment because of your use of nasty language. If you are not able to leave a comment without swearing then I am not going to post it.

      Just in case you were not aware, there are good and responsible people out there who have never owned a Tegu before.

      Heather, potentially all reptile pets can carry salmonella, but it is not really an issue unless you are immunocomprimised, like to give your Tegu open mouth kisses, or are used to sharing a feeding dish with your Tegu. Seriously, it is not something to worry about. Use common sense by washing your hands after handling your herps and you will be fine.

      Great article! I'm just curious to know, do Tegu lizards carry samonella? I know some lizard species do carry it, but I've heard it's more prevalent in amphibians. Having a hard time finding that information.

      Izzy, we have a dog problem all over the world because inexperienced and irresponsible people get dogs and let them loose when they become large and less fun to handle. Does that mean that only experienced people should get dogs?

      We have a Tegu problem in the Everglades because of inexperienced and irresponsible owners that let this animals loose when they get too big. Please don't get this as a pet thinking it's like a cat or a dog, this is a large lizard and if you are not experienced with it, it will be too much for you to handle!

      Okay I'm convinced that I will be getting a Tegu Monitor! I have 3 redtail boas and 1 Brazilian rbw board and was thinking about getting a Retic or a Burmese python then I seen someone trying to get rid of a Tegu witch was spoken for but started reading up on these and makes want one better temperment not as expensive to feed, and I have cats and dogs too! Just seems to be a great pet! Thank you

      Hi again, Yes, I'll certainly check out Pinterest for your tegu pics. I don't think I've ever seen one in any of the Australian zoos I've visited.

      You're right - often the response to telling people I have pet snakes is "Eww, gross" or an expression of pure horror. Reptiles are fascinating, not gross.

      Oh, they do well without the worms or cat food! That is the best part of the beasts, as they will eat about anything--guinea eggs from my incubator, hot dogs, etc. I have offered mine several types of seafood but he does not like that, for some reason.

      They are native here to South America or would probably be banned here too. I know you guys have a lot of great Monitors in your part of the world, but I am happy we have the Tegu over here and would not trade them for any other Reptile.

      Check my Pinterest page when you get a chance. I have a group board about Tegus and there are some really good pictures on it--a lot better than the ones on here.

      It is nice that someone from HP read this without saying "Ewww, gross." I imagine you get that a lot when other hubbers read about your snakes.

      Jean DAndrea 17 months ago from Victoria, Australia

      Now you've made me want to get a Tegu! Don't think they are permitted here in Australia though. Your guy sounds like a really great pet. Most of his diet sounds good to me as well. :-) Not the worms and cat food though.....

      Tegus seem to have a "live and let live" attitude, Alphadogg, so if my dogs don't mess with them they never mess back. There are some hunting dogs around here missing chunks out of their noses, however.

      Burmese Pythons are getting a lot of bad press. I expect to see more laws against them in the future, and legislators up your way telling us how they are the Pit Bull of the reptile world. Take care of Buster and keep him under wraps.

      Great hub Doc, I am also a reptile lover, I have a 9 ft Burmese Python named Buster that I absolutely love. I don't have a lot of knowledge/experience with the Tegu. I did watch a documentary about how they (along with the Burmese & African Rock Pythons) were a problem in Florida. The showed perceived them as extremely aggressive, & with those teeth, I would want my kids/dogs losing a limb.

      If you are into that sort of thing, of course!!!!

      I don't really like reptiles, but I was interested in learning about tegus and why they are great pets. You certainly have a lot of animals in your house! Wonder if I'll end up seeing your home in a TV show or something...

      The article is very interesting, and your home sounds most intriguing.

      Interesting read. I was a zoo docent in the 90's and we had a tegu as one of our education animals. My knowledge of them was limited to bullet points (range, habitat, diet, reproduction, etc.). Had I known they were as much fun as you indicate, I'd have worked with our's more.

      I preferred to work with our ball python, emperor scorpion, or red phase screech owl because they elicited a greater response from the public. The tegu, unfortunately, seemed to underwhelm people. Voted up and interesting.
