I recently posted about thinking my female unspayed cat was peeing in clean laundry. I took her to be tested for a UTI and it came back negative. Then today while I was in the closet I saw my male cat squat and pee in my boyfriends basket of socks. This is only the second time he's done this and while I had the closet closed he didn't pee anywhere else. Could this be behavioral or is it possibly a UTI?
