My 2 year old spayed cat has had some urinary tract problems for 7 months now and has been urinating on carpet, rugs, clothes, etc. My younger 8 month old cat (who is not spayed and has no urinary tract problems) has just recently started copying the behavior. I have bought sprays that are said to keep cats from soiling certain areas, but they aren't working. I know there is not much I can do about my older cat except antibiotics to treat the recurring infection (which haven't helped thus far, and I'm very poor and can't afford so much to take her to the vet every two weeks just to be diagnosed with the same thing and given the same antibiotic), but is there anything I can do about my younger cat's behavior? Also, any other advice would be greatly appreciated!
