My cat has a problem that when she pees in her litter box she raises her butt out the door and gets it all over the floor and not in the litter box. I hav tried a litter box with a door but she leaves the door on her back and still pees out of it. I have had previous cats in the past and they all have squatted when they pee. My cat now starts squatting and then raises her butt. Can anyone recomend a litter box deep enough or does anyone know how to help me change this. Thanks
