Mites could have gotten into the food. Mites can cause hair loss to hamsters and other small rodents. Also, it could have been old age. Hamsters will live 1-3 years. If you have a 2 or 3 year old hamster, it could loose hair. Especially the males.
It sounds like your hamster has mange. Get him to a vet ASAP
Most males lose hair around their skirt or back half. I wouldn't worry too much.
well my hamster started losing bits of his fur when he was about 2 and he is over 3 years old now. just because its losing fur, doesnt mean it will die soon
because it might be very sick go to a local vet.
In winter my hamster mr.Tinkles would grow long long fur. And when it was getting warmmer he was loosing it. He was a Teddy Bear hamster so im not sure if panda's and Short furred are like that.... I will have to wait ecause I recently got a panda bear and 2 teddy bears
i don't think it's normal. You should take it to a vet.
its very shy and wont come out of its den and its starts losing its fur
Natural talent
It happened to my hamster, he is probably just getting old. If he starts to lose all his fur check his food and bedding, he could have mites. Either way take him to the vet if he loses more fur!
What if your hamster has mange
If a hamster is bald or is losing its fur, it may be rubbing up against something which is causing it to lose fur. Your hamster may be old enough to be losing fur. I have a hamster who is nearly 4 and isn't bald, but i also have a hamster who is nearly 2 and is half bald. She has been confirmed for mites and is being treated with antibiotics. If your hamster might have mites, i would suggest going to a vet. If you haven't cleaned out your hamster in a while do that, and it might grow back. I cleaned my hamster out and it grew back for a while, then went again so i changed her cage with a bigger one, but she was still bald. our hamster might even be stressed so place him/her in a quiet place and place a house inside the cage so she/he can retreat there when stressed. Try and calm him/her hold him/her and talk to them so they know you are there. Hope i helped. [: And good Luck.
Yes, hamsters do have fur.
