My cat, Tiger, stands to pee in the litter box, and therefore sometimes pee escapes in between the box and its cover and gets on the floor. He doesn't stoop to pee like a regular cat does. He stands, raises his tail and just pees. We have 3 cats (all males and neutered) and Tiger was the last to join the household 2 years ago. He was a small kitten then, and we noticed that he stood up to pee even then. My wife even once saw him raise his back leg like a dog to pee (he also fetches like dog, bringing back his toy for us to throw again...strange). Anyway, we have 3 litter boxes which are always kept clean, and he uses them all. It's always easy to know when he uses a box because it'll have pee on the walls of the box. he doesn't pee outside of the box (thank God), and i can live with him peeing upright. It's just so strange. Anyone ever heard about this?
