I know this subject has been posted everywhere to death, But I am at my wits end now. For over a year, my 10 yr old female cat will urinate on plastic bags if one is on the floor, clothing, sheets used to cover leather furniture, door mats, and the floor itself. We also have a 15 month kitten too, but the kitten is fine, and uses the litter boxes all the time <Thank God the kitten has not picked up the habit of peeing and pooping where it wants to>. Now the 10 yr old did have some blood in her Urine 4 months ago, we took her to the Vet, and he gave us an oral antibiotic to give her. then she seemed fine for a few weeks, but now she is doing this again. I swear I cannot stand cleaning up urine and poop all over the house, or accidently stepping in it anymore. We called the Vet about it occuring again, and now he is telling us (by phone and not seeing her again) that it sounds like a behavior problem. I don't know what to do anymore. I almost feel like trying a new Vet for the 10 yr old cat.
