My cat brother Kyle has started peeing outside the box At first they thought it was me doing it but then they caught him in the act. Nothing has really changed around here so we don't think it's stress of any kind. Today they're taking him to the vet to get tested for a urinary tract infection. If it's a UTI will he go back to using the box after it's cleared up? If it's not a UTI then what could it be and how hard will it be to train him back? I sure hope Kyle's okay and that we can get things back to normal around here. Any ideas, insights or words of encouragement are welcome.
