I'm sure, having pets is rather like having kids. I mean, they are cute and cuddly but have a will of their own. When you want to play, they would rather sleep, but when it is your turn to rest, they want to play. Plus, the inevitable heartache when they fall ill.
Alas, poor little PipSqueak. She had to go to the vet because there was a tiny lump on her foot. We were horrified! It was diagnosed as an abscess, and the vet squeezed it out. And the naughty hamster gave the vet a good nip *ouch* :P At least, it isn't a tumour. Sigh, we have to clean the wound on our own until she is well. It is dreadfully difficult to forcefeed her antibiotics.
TwinSqueaks gave me a fright when I noticed some wet erm...animal litter in their cage. Hauled them from their beds to check their tails, just in case.
It isn't always a bed of roses, this pet-owning affair.
