My cat Chloe is 5 years old. For the past 4 months she has been periodically unrinating on my bed. I have taken her to my vet where a urinalysis was performed. The results were negative, however my vet still perscribed Chloe Chlavamox, "just in case." It seemed to work for about three weeks. Chloe urinates on my bed less often than she did 4 months ago, but it still happens about every month. When she urinates on my bed, I spray the area with solution that supposedly takes the scent away, and wash my bedding. Three days ago she also unrinated on a plastic bag that was on the floor. I am freaking out and would love to hear a new approach to this problem.
