Poor Blondie-Boy

My cat has a gimp. I stepped on him last night (he got under my feet in the kitchen and I didn't know it), and he started limping a few hours later. He doesn't, apparently, hurt badly enough to jump on my desk, scratch at my furniture, or hang from window ledges and door (and for this reason, the vet said I probably didn't need to take him in, unless his limp got worse or he started acting visibly sick). But still, he's my kitteh-baby, and I worry. But really, does this look like a hurt-kitty?
