I can't Misty is 14 years old. About a year ago she started urinating outside her box, but she also uses her box as well. It's odd because I've tried other litters and she still prefers the one I use, and she doesn't urinate outside of it all the time and we keep it clean. Plus another thing she does is she gets out of the box, and then she scratches on the ground around the box like she's trying to cover her waste, but she's no longer in the box. Has anyone else heard of this? Also she's been checked out by the vet and all is fine so he is recommending amitriptyline. Anyone have success with it? Thank you!!
