Pouncer, Pouncer, Pouncer! You are forever worrying your poor meowmie.
I'm thinking that if it were broken he probably wouldn't want to put a lot of weight on it and wouldn't want to do much jumping. Of course, this is Pouncer we are talking about! Hopefully it's nothing serious and he will be up and running soon. I would just keep an eye out and make sure no infection develops if he does have something stuck in there.

I hope you feel better soon Kim. I know you have been miserable lately. That flu is nasty stuff.
