That's the ticket!

Yesterday Mrs. Drang had to take Sparrowbane to the vet. He was obviously limping and in pain in his left hind leg. We were afraid he'd gotten wounded in a fight or something.

Back at home now; no sign of a wound, but his left hind leg seems to had a muscle strain.

Obviously, he needs to stretch more often...

EDIT: Realized that, in my haste to get out the door to work, I included the picture but not the source.
Which is, of course, I Can Haz cheeseburger.
