Hi Marilyn,
My husband and I have four cats: 8-yo male Bengal, 3-yo male F4 Savannah, 9-month female Savannah, and 7-month rescue kitten. The F4 boy, Tafi, has had issues with peeing in the house - on rugs originally, and now on cat beds in the front window. He *occasionally* also pees down the kitchen sink drain - but that doesn't bother us much, as it's easy to clean.
His peeing seems to be set off by dissatisfaction with his litter box. Then once he has marked a spot, he re-marks it. I got rid of a shag rug that probably had traces of smell in it, despite my attempts at cleaning (with Anti-Icky Poo and Woolite Pet carpet cleaner). Originally I think he was peeing on a rug because one litter box was an automatic one that he didn't like. Finally we found a system that everyone liked: Two large, simple litter bins, one up and one downstairs. Both are enclosed in custom-made wood boxes. Litter type is consistent, and we keep them full and clean every day.
Things were great for a few months, until I found out I was pregnant, and my husband took over cat box duties. My husband moved a Litter Locker into the potty area (big wood box). When we ran out of the odor-sealed bags for Litter Locker, he temporarily put in a regular plastic bag. I could tell that the area smelled different. Suddenly I started finding cat pee soaking the cat beds in our front living room window. I cleaned with Anti Icky Poo and bleach, but perhaps the smell didn't come all the way out - ? Even though the beds smell clean to me, and the litter box is back to normal, Tafi has continued peeing in the beds.
I tried getting rid of all the existing cat beds, and putting out a completely new blanket. He peed on that too, after a couple of days.
Behaviorally, all 4 cats get along. The oldest (Tigger) was jealous for awhile because Tafi had bonded with the kittens, but Tigger and Tafi seem to have re-bonded now. There is sometimes mild irritation when a kitten wants to play and an adult cat doesn't, but generally there is harmony. All cats do play together sometimes.
I don't know how else to figure out why Tafi keeps peeing on those beds, and how to stop it! Another thing that occurred to me is that maybe he senses change in me (I'm pregnant) - ??
Thank you so much for any advice you have!
