I'm guessing that means pounce and bounce? (And the binary opposite - pass out entirely.)

Someplace, at a previous boyfriend's house, there are pictures of what one can do with kittens who are passed out entirely. Think kitten-sammitches.

I like reading about your fosters (and other stuff, too). I'm not sure if I have the strength to give up kittens I fostered, nor am I sure that the reigning feline would permit me to have them. She firmly opposes quadrapeds of any flavor.
