My sphynx is VERY inbred and has astronomical anxiety. I try to make sure he is loved enough, has access to his water fountain, good food quality and variety, and is entertained. Throughout his life he had struggled with peeing in his litter box. I've tried everything. I test his urine, no infection, I moved his food to the place he peed (he just peed in a new place), new litter (no difference), different litterboxes (nothing). I also clean them 2x a day (2 cats now, but even whrn I just had him). The problem is he just gets worse and worse. We have moved a couple times and every time he adopts good bathroom behavior. But slowly he will start peeing next to the litterbox. I used to keep a crate floor insert under the litterbox to cut down on mess, he started peeing on that and wouldn't stop. So I got resigned to cleaning that all the time. Eventually, however, he just started peeing everywhere. This move he did fine for a week. Lots of love, settled in nice, no big issues. The litter box is the kind that is a dome with a ramp entry (I keep the top off), well week 2 I notice he's peeing in the ramp. So last week I went away on business, and I know this is stressful, but he is being watched and cared for. When I come back he's being peeing I the ramp, and I suspect everything else as he attempted to just squat and pee in the middle of the floor. I'm at my wits end. One could say it's stress, but this is consistently happening without stress. I know it is somehow behavioral because he repeatedly develops good behavior that worsens. I've adopted pee pads which work for awhile, but he always just ends up peeing everywhere. Insight is appreciated. I partially believe this is part of his inbreeding. I'm planning on getting anxiety cbd oil tomorrow for cats. Anybody know if this is effective? I'm debating between sprays, wall emitters, kitty prozac, and edibles/drops. Or a combination. I really want to work this out. Thank you guys!
