penny has sad legs

Sad knees, to be exact. She has been diagnosed with luxating patellas, which basically means that her kneecaps are slippery. She has it in both of her back legs, though it seems to be worse in her right leg. It's very very sad to see when both of her legs slip and she has to sit down because they won't hold her up. So sad. Look how sad she is.

I'm heading to the vet tomorrow with her to find out just how bad it is, and if she will need this terribly expensive surgery. Cross your fingers!

Update to come regarding my week of physical fitness.
