Our kitten is peeing on our bed
We adopted a female kitten, Bella, 2 1/2 weeks ago (she is about 3 months old). According to the Cat Rescue place, she was born approximately 1 May 2009. Bella and her litter mates were found around 5 Jun 2009, supposedly abandoned by their mother. I realize kittens shouldn't be separated from their mother that early, but my wife and I decided that we should adopt a rescued cat just to do our part ;) . When we got her home, she stayed more or less hidden for about three days. We finally coaxed her out of hiding, and she has since then become the sweetest, most loveable cat I've ever had. She seems to be very comfortable sleeping with me and my wife, so we have let her. One other note, my wife and I have a downstairs bedroom suite which is quite large, and the kitten stays in that suite. One of our sons has moved back home, and he has a 10 year-old cat that stays upstairs and outdoors. I haven't introduced them as of yet. Bella does not share this area with any other pets.
My wife and I have completely fallen in love with Bella. For the first 9 days, she used the litter box every time without any accidents. On the evening of the 10th day, I was laying on my bed watching TV, when I suddenly felt something warm on my arm. I looked and saw that Bella had urinated on the bed right next to my arm. The next day, she peed on our comforter twice (it was washed in between). It was a down quilt. The next day, she peed on the quilt again. Thinking that perhaps she was attracted by the feathers, I removed it from our room. We put a new blanket on our bed, and everything was fine for a few days. Then 2 days ago, she peed on the new blanket. I washed it, and that evening, she peed on it again. Yesterday, we used a bedspread on our bed. She didn't pee on it for the entire day. This morning, I woke up to see her peeing on the bedspread. I washed it, and now this evening, she just peed on it again. Oh, and one of the times she peed on the bed, I actually saw her urinating in her litter box not 5 minutes before peeing on the bed.
We took her to the vet about 5 days ago, and she has no UTI. We are never the slight bit mean to her. We were told to try spraying her with a water bottle, but I don't really want to try that. My wife and I never fight and we keep her area completely calm. She still uses the litter box every time for poop, and for urine most of the time. It can't have anything to do with the cleanliness of the litter box, as I am obsessive about cleaning the litter box, because I hate the smell of urine and poop (I scoop it at least 3 times a day). Unfortunately, Bella's litter box now smells way better than my bed. At the rate we're going, I am going to have to start buying new blankets twice a week, not to mention a new washer and dryer when they wear out. In fact, I am most likely going to have to buy a new mattress now. Please HELP! I love her so much and I can't see myself getting rid of her.
