Hello all! My female cat Izzy has starting doing something strange out of the blue. She has started peeing and pooping on my brother's bed. We thought it was because she was upset about the fleas, so we treated her fleas. And treated the house for fleas. But, she did it again this morning. This is about the 3rd time she has done this. We have been discouraging our male cat from using her litter because we think it's part of the problem. But I wanted to get some insight from others. Has anyone else dealt with this issue? I don't want to have to put her on meds but if this continues she may need it. I have thought about replacing the litterboxes themselves and starting new.
