-----Question-----
My dwarf hamster is about a year and 3 months old. Over the past two months he has lost quite a lot of weight as he was a bit chubby. He isn't eating or drinking much and whenever i pick him up he isn't cold but is always shaking, but he is always running on his wheel. What is wrong with him?

Dear Sophii,

Please get your hamster to a vet! The sooner the better. I am not sure exactyly what is wrong, being that I would really have to see it to tell, but a vet will be able to give a proper diagnosis. This sound pretty serious, so make an appontment for the vet a.s.a.p.
If you still ahve any questions, e-mail me back!
Sincerely,
Sarah

Is it just because he is getting old? Also my other hamster has no fur on her arms and it seems very sore as she sqeaks when i touch it, what could be wrong?

Answer
It is possible that age is the problem, but since your other hamster isnt doing well either, I really dont know what to say. It may be too cold/hot/humid/dry for them, it could be their food, or water. I really don't know, but please talk to a vet about it.
I am sorry i can't help you, but i don't want to make an incorrect diagnosis. just try to keep them comfortable and safe, and talk to a vet.
Sorry, again.
Sincerely,
Sarah
