Hello all! I recently got 2 female 8 week old Sphynx kittens! They are sisters. One of them took to the littler box like a pro. The other is randomly urinating on the floor and once on the couch. They were fixed about a week ago and the incisions sites are healing appropriately. I asked the breeder what she thought it could be and she is not sure either. We use the exact same litter as well. She is painfully shy so I am wondering if this is anxiety related? She naps more than her sister also. She is slowly starting to come out of her shell. We have also put out an additional littler box. Any advice on this would be so helpful, thanks!
