My sisters cat is about 12 or 13 years old and he has started peeing on pillows, blankets and clothes. we have 4 litter boxes for him in the house that are always kept clean. We started feeding him 9 lives urinary track control cat food that's what the vet recommended. He is also on medicine for acute Kidney failure but is doing really good now. I just can't get him to stop peeing everywhere he isn't supposed to.
