My daughters hamster fell down the stairs while in his cage... he still comes out of his igloo, walks around and he even climbed onto it at one point before going back into it.. Should he be brought to the vet? What could they do for him??

Hamsters are hard to help medically. If he isn't in pain and moving all limbs I would assume he's ok. If he's not acting his normal self then I would bring him in. There just isn't alot they can do for hamsters. They also have a 2 year life expectancy. If he's hurt or not acting normal the vet will give you the best options to help.

It would be best for you to call the vet and explain the situation. Best wshes, I hope the little guy will be ok
