My sphynx is about 4 years old. She is completely lovable and spoiled, definitely no issue with attention. She's started a habit of peeing everywhere. Couch, bed (most frequent), clothes left on the floor, etc. She was taken to the vet, no UTI or anything out of the ordinary. She pees in her litter box still! We've even added a new litter box, removed the top over one, and even switched out her litter but nothing changed. Pooping in the bed under the covers was even an occurrence. She's not allowed in the bedroom unless someone is home with her and sitting with her, for obvious reasons. It was thought that she was urinating in her sleep, that has since proven to be wrong. She is peeing on the furniture every day, sometimes even twice (twice during the night last night), and even started making eye contact when doing it. I am running out of options, sanity, and bed sheets. I don't know what to do to help her. She is fixed so the vet thought MAYBE a bladder issue with that and mentioned medicine, but recent events are leaving me questioning that. Any advice is greatly appreciated as I really don't know what else to do.
