Oh yeah, my two kittens (and any kittens for that matter) were notorious in this matter. Play like nothing matters for half an hour, run, jump, sprint, crawl, scratch, everything like your life depends on it. And then just fall down on the spot for like an hour or two, followed up by a repeat of the same cycle. It's cute to watch, but also kind of scary. They just look _empty_ after that intense a playtime.
