I have two cats, one male and one female, brother and sister, neutered and spayed. They’ve been together since we adopted them from a shelter 1 1/2 years ago. I thought one or both were spraying in a corner of an upstairs hallway some months ago, but I treated that and believe it stopped (I put a temporary obstruction there for several weeks). No spraying for several months. But then just the other day, I smelled cat urine in our family room coming from behind four theatre seats we have against a wall. My husband said he didnt smell anything and said it is just the litter box (he’s wrong, why am I the only one who notices these things?). Last nite, I placed a line of foil behind the chairs, hoping to keep the cats away until I can treat it today (cats hate foil, right?). I just moved the chairs away from the wall and saw claw marks and torn foil, along with a puddle of urine on the foil! Ugh! Once I clean this up/treat the carpet, how will I put a stop to this? I know about taking them to the vet...I dont think that is the problem but rather a behavior problem. My cats generally get along, play with each other, sleep together sometimes, and groom each other. Clearly they are bonded. But the male does seem to be a bully at times and plays too roughly (the female growls a lot, but sometimes even hisses). I guess I need to buy the Feliway diffusers, but if anyone has any other ideas re: how I can protect my carpets and my sanity, please tell me. I just want a happy, clean-smelling house without it requiring that I be scrubbing behind them all the time. I love them terribly, but can’t live this way! Please tell me it will stop.
