I guess my questions are... does you cat drink plenty of water? Why would the vet have an indication of a UTI? One accident outside of the box is not a diagnosis of a UTI in my opinion.My cat shows non of those sign other thatn he peed once that i know of outside the litter box. the vet said he might be getting a UTI but just told me to switch foods. He didn't give me any sort of medication. Is there anything I can do to prevent one other then switching his food?
