Just got hamster, and already there's a problem... +rep
Hi all :)
Well I just got a dwarf hamster from my friend. I paid £20 for the hamster and a complete cage setup. The hamster is around 2 years old, but I have only just noticed something. It has this huge lump on its behind. Honestly, its almost the size of his tummy, shaped like a large nut. Its a boy so it cannot be pregnant. What could it be? Has anyone had something like this before on their hamster?
All good answers receive +rep :)
