My dwarf hamster is lethargic, won't eat or drink, and just sleeps.

Updated on September 23rd, 2025

My hamster is a Russian dwarf hamster. She has always been very active. She is about sixteen months old. When I was went downstairs I noticed that she’s incredibly lethargic, won’t eat or drink. Not even taking her favourite treats. She just wants to sleep, and just slumped on her side with her eyes closed.

I'm sorry she isn't feeling well! A good first step would be to make sure the environment she is is warm enough as hamsters can go into hibernation if their environment is too cold. Making sure she has plenty of access to fresh clean water and food, and fresh bedding may also help.

If she still doesn't perk up after these changes, a vet visit to rule out any health issues is best.

I am so sorry that your hamster isn’t feeling well. There are many possible causes including injury, dental disease, organ failure, heart disease, and cancer. Is she eating? If she is not eating then the is at high risk for this being a fatal event. Hamsters can not go long without food. I would encourage you to have her evaluated by your veterinarian as soon as possible. Look her all over to look for any injury. Make sure she can get to food and water without having to move much. Best of luck and I hope she improves soon. Thank you for using Pet Coach.

I am sorry to hear about your hamster. This behavior (or lack of behavior) is quite concerning. You could try scooping her up with a cub or bowl if you are afraid to touch her. If it is cold where you are you can also put her into a warmer room. In very rare instances hamster can go into a hibernation type state but this is not common at all. If she is still alive/responds to touch but is weak then unfortunately there isn't much you can do at home, so I would try to get her into the vet for an exam as soon as possible. Unfortunately some of these little guys only live 1 to 2 years.

My hamster is lethargic, tired, and dragging her legs. Is she sick?

She may not be dying, but she looks and is behaving as if she is seriously ill. You'll need to have Latte physically examined by your veterinarian to diagnose illness or injury though. In the tank, clean and sanitize her cage, bowls, toys and hides. Discard anything that cannot be sanitized. Keep her warm and as stress free as possible until she sees the vet. Offer small amounts of water or unflavored PediaLyte and moisten pelleted food to make eating easier.

My hamster is lethargic and not drinking. Does he need a vet?

Thanks for reaching out about Travis. It is highly recommended that you take Travis to the veterinarian. With him being lethargic, not eating much and not drinking well, it sounds as if she is very sick. Trying to get her to drink some water might attempt to re-hydrate her. Good luck.

Why is my hamster sleeping so much and dragging her back legs?

If she will allow, check her teeth for overgrowth or misalignment. Make sure her cage is warm enough and away from high traffic areas, strong drafts/vibrations and loud noises. Monitor for loose droppings, lethargy and a decreased appetite. Although most hamsters are more active at night, this may simply be her personality. An exam with your veterinarian is always recommended to make sure she isn't sick or injured.

Why is my new hamster sick? She won't eat, move, or open her eye.

This sounds like Peanut may be very ill or in distress. I would bring her to your vet as soon as possible. Until you can get to a vet, keeping her in a quiet, warm, darkened area with plenty of food and water may help her to relax enough to settle some.

Why is my hamster sleeping and drinking too much? Is he sick?

Hello, I'm sorry to hear that KitKat hasn't been acting like himself recently. Anytime an animal has a change in appetite or thirst and is acting lethargic, I recommend a physical exam from a veterinarian. Increased thirst may be a sign of an endocrine disorder, kidney disease, or a reproductive tract disease. Lethargy and inactivity is often a sign of pain and feeling ill. I hope this is helpful.

Why is my new hamster sleeping all day and not eating or drinking?

Thank you for using PetCoach. It is important to remember that hamsters are nocturnal animals. That means the majority of eating drinking and activity will be done at night. She is also stressed by the change in habitat and abnormal activity. Try to minimize handling for the next few days, especially during the day time when she should be asleep. Here are some articles that may give you some more information. If she is not active at night or eating or drinking, then I would recommend a veterinary visit tomorrow. https://vcahospitals.com/know-your-pet/owning-a-pet-hamster https://vcahospitals.com/know-your-pet/owning-a-pet-hamster https://bellevueanimalhospital.com/veterinary-services/exotic-avian/hamsters/ https://lafeber.com/vet/basic-information-for-hamsters/ https://lafeber.com/vet/wp-content/uploads/hamster-basic-info-sheet.pdf
