In the 44 years I have shared my heart and home with felines, I have been owned by only one intact Russian Blue male who sprayed. This happened once! Algernon was was in the middle of a show career as an adult. He was 14 months old and had never displayed a proclivity to spray. Of course, he was neutered the next day. I would far prefer to show a cat in Premiership classes ( for neutered cats) than have my house reek of cat urine. Neutering was an instant cure. There was never another episode of this undesirable behavior.
Now I am in a total quandary. We have three cats. They are all altered and indoor cats. Trouble, our 8 year old white Oriental shorthair is slightly neurotic so is presently under treatment with the anti-anxiety drug, Buspar. He tends to over-groom, pulling out large chunks of fur, resulting in a motley appearance. His disposition is very sweet and always easy to handle. His favorite past time beside eating is being doted upon with love.
Our lilac-point Oriental shorthair, Hush Puppy, also 8 years-of-age, is the gentlest of cats and loves to play with toys. His favorite activity is crawling under the covers with me, or to sit on my hip while we watch TV. Although he is the shiest of the three, Hush Puppy's purrs can be heard from quite a distance. He loves to bask on the hammock in front of the window in our bedroom, soaking up the sunshine while he naps. His rank in the hierarchy of our feline residents is the bottom of the totem pole.
Lucyfur is the youngster at three years old, in our house. Spayed and microchipped at three months-of-age, she was adopted from our Veterinarian's clinic. Lucyfur has a very strong personality. The word, "determined" comes to mind, in describing her disposition. While she is an affectionate kitty, when she makes up her mind to pursue a project, nothing in the world gets in her way. We think she is the dominant cat in our household, and strongly suspect that she is the culprit in our recent dilemma.
All of a sudden last week, we discovered that one of the cats was spraying the side of the bed, mattress, box spring and its metal frame. The carpet under the bed is impregnated with the pungent stench of cat urine. Our eyes water upon entering the room. We don't have a clue about what is causing this sudden aberrant behavior.
There is nothing new going on in our home. Schedules have not changed. We continue to have regular playtime with the cats and their favorite interactive toys. There have been no variations in feeding schedules or food. Our veterinarian examined the cats this morning so we now await anxiously for urine test results.
We are aware how deeply territorial cats are in nature. Since there have been a few noisy stray cats roaming the neighborhood recently, it is possible that this has triggered territorial marking behavior. Every window in the house is now closed.
And yet the spraying continues in spite of our using a pheromone product designed alleviate this behavior. We are at our wit's end with frustration, and truly hope that the cause is medical.
Update: Veterinary results of urine test: Struvite Crystals (FLUTD) which requires dietary change to higher protein, low carbohydrate ( no grain) food.
Thanks to everyone for the excellent comments and suggestions offered. It really is crucial to check for possible medical problems that may be the cause of inappropriate feline elimination behaviors.
I am so relieved that this is not territorial behavior raising its ugly head. I will post an update following her course of treatment, and results of her follow up exam in two weeks.
