Why Isn't My Guinea Pig Drinking Water?

I love small animal pets such as guinea pigs, bunnies, and rats. I enjoy sharing my knowledge of how to raise healthy pets.

Find out if your guinea pig is getting enough water, even if it never drinks from its bottle or bowl.

When you first get a guinea pig, or perhaps after several weeks, months or even years, you might notice that your guinea pig never seems to drink. Water bottles stay full, water dishes are used as toilets and yet somehow your guinea pig still seems healthy and happy. What is going on?

Is It Normal for a Guinea Pig to Not Drink?

As it turns out, a healthy guinea pig being fed a diet of fluid-rich vegetables (celery and cucumber especially) does not often need additional water. They seem to be able to get all the fluid they need from their vegetable intake—now you see why it is so very important to feed your guinea pig fresh vegetables every day! Guinea pig pellets and hay are part of a piggie diet, too, but fresh, nutrient- and water-filled vegetables truly are essential for the health of your guinea pigs.

Many people notice that as their guinea pig's veggie intake goes up, their drinking goes down. This is nothing to worry about and may even be suggestive of the fact that you are feeding your guinea pigs very well!

Water Intake Changes Over Their Life Span

It is also worth noting that a guinea pig's water intake can change over the course of their life. As my guinea pig boar has gotten older (and had a diet more rich in the celery and cucumber mentioned above), he has almost stopped drinking from his water bottle completely. Yet he remains happy, healthy and alert.

So Does This Mean Guinea Pigs Don't Need Water?

Guinea pigs need water! Even if they're not drinking it, you should refresh their water every few days. You never know when a thirst will take them. Like all animals, guinea pigs should always have fresh, clean water to drink.

When Should I Worry?

If your guinea pig seems ill and listless (that means not moving around much), then that is a sign that something is wrong. A sick guinea pig will not behave like a well one, their coat may be rough, their eyes may be half-closed all the time and they may not respond to things they usually respond to. If you find your guinea pig in this state, a trip to the vet is in order.

Go to the Vet If Your Pet Isn't Eating

If your guinea pig is not eating or drinking, that too is a sign of a more serious condition. For guinea pigs, eating vegetables is far more important to their well-being than drinking water from a bowl or bottle. If your guinea pig has stopped eating, you definitely need to take him or her to the vet.

Animals exhibiting signs and symptoms of distress should be seen by a veterinarian immediately.

      Big thanks! One of my piggies expends almost 12 hours without drinking (or maybe not drinking that much to be noticiable) and compared to my other piggie... Well, she ends the bottle in less than 12 hours everyday! She behaves as normal, but I'm a worryesome owner so I couldn't help to google and look at this page hahaha!!

      I just moved my 3 guinea pigs to a new bigger cage (also in a different room). But I’ve been noticing that they haven’t been drinking water and still eat but not as much without me giving it to them. Is that a problem or is it just them getting used to the new area? I also fed them a little more veggies yesterday than normal, do you think that is the case?

      I always buy Oxbow Western Timothy Hay for my guinea pigs. They won't eat anything other than that. I hope that answers your question, Jane and Natalie.

      I have two girls; Connie, quite the personality, was the boss until little Ezzy (Esmeralda) waited about 3 month if extreme underdog, timid submissiveness is now "boss" but in a confident stable mood, relaxed way. Biathlon are just my little loves although I got them fir my 11 year old daughter.

      What is the best Timothy hay? Bought some Carefresh 1st cut and it is awful!!!!

      I got my guinea pig today and when I put him in his cage around 12:00 and now it's 8:35 he has been hiding in his hide house all day. Everytime I go into my room, he runs away so scared. Then when I leave, I peek in the corner and I see him eating his carrots, I'm scared that he is going to be like that all the time and i won't be able to cuddle him and take care of him that much bc he is scared of me. What shall I do?
