Q. Female cat lifting her butt/twitching while in litter box, pee goes out onto the floor. Urine sample clean vet can't tell me why she does it.Thoughts?

A. This twitching and peeing behavior sounds like your cat is spraying. This can be a behavioral thing. I would recommend a different type of litterbox with a front door so that she doesn't miss and potentially get urine on the floor. As long as she is trying to go in the litterbox you can try to see if a change in litterbox will suffice. However, there are medications to help with spraying behavior, I like Clomicalm and Fluoxetine for medical therapy. For more natural products you can try Feliway plug-ins placed near the litterbox.
Try this litterbox, this works great for my female cat who sometimes goes a little too high- http://www.amazon.com/Catit-Jumbo-Hooded-Cat-Litter/dp/B003RQVGKC
