Hamster Sore...?

Question

My hamster has a lump on one of his fingers on his right hand. He's had it for a while now. Anyone know what this is?

Answer 1

Does it look like a tiny sore or a substantial size lump?

It it is tiny sore, it could be an allergic reaction to the bedding. Try to use only aspen shavings or carefresh since most of the other beddings tend to cause allergy to hamster paws when they walk on them.

Hamsters are also very prone to tumours and cancers, so if it is significant sized lump, I would advise you to take him to a vet immediately to rule out the same / undertake treatment.
