I think my poor kitty broke his ankle :'(

I came home from town to find Harry, my Siamese kitty, on the back porch. His ankle is all swollen up and looks like it might be broken or something. Poot thing is all unhappy. He's curled up now in the desk chair he stole from me and sleeping. Demoting me to the less comfortable of the desk chairs. I don't mind though, my poor Harry kitty can have the other comfy chair if it makes him feel better. He is sleeping better in it. I meanwhile am surfing the internet looking for anything on what a cat can have for pain.
