Ziggy has been peeing in my room in random places and occasionally in other areas of the basement. She just turned 3 and had her first UTI a month ago that was treated with antibiotics. I took her back in for a follow-up last week and they checked her pee and she was given a clean bill of health. I haven't changed her litter or introduced anything new that I can think of into the home. Her eating and drinking habits haven't changed. I'm at a complete loss with her recent behavior please help
