Why is my dwarf hamster sleeping all day, hiding, and not active?

No, I would not be overly worried. He may just be tired from stress. Just keep an eye on him and if he isn't better in 24 hours you should take him to a vet for an exam. He may be coming down with an illness; very common, especially if purchased at a pet store.

Pompie is probably not as active as usual because of his new surroundings. Hamsters can be very prone to stress when their environment abruptly changes. He is most likely being more active when he is home alone and at night time because he feels safer. Since he is eating and drinking normally, I would not be too concerned. I hope this helps.

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.

I am sorry that Snowy is hiding under the running wheel. This can be a normal behaviour if something has spooked her. However, it can also be a first sign of a sickness. I would monitor closey for signs of illness. This would include changes to appetite, energy levels, or any changes to her fecal movements. If you suspect she is ill I would take her to a veterinarian for a check-up. Best of luck and I hope Snowy is her normal self again soon.

Its hard to say if Pepper is sick without more information. You are correct that most hamsters are active at night time. They usually like to run in their little wheels and scurry about the cage. You need to watch for any signs of diarrhea or wetness around the rectum. When Pepper is awake, are his eyes open or half closed? Is the food being moved around? Many hamsters pack the food to their nest to eat later. Also, offer the pellets as well as the seed mixture. When he is awake, is he active? Most pet stores have a health warranty on their little critters. If you are seeing signs of illness, call the store to ask about having Pepper checked out.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. There could be many possible causes of these symptoms. I worry about a systemic infection or illness. I would recommend taking Dave in to be seen by a veterinarian so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

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.
