I have a Himalayan male cat and he seems to have UTI's often and major issues with NOT using the litter box to urinate. He will go all over the floors in certain areas and lately is going excessively. Has anyone had any experience with this or knowledge of what might be going on. He is also diabetic. We have him on a new antibiotic and hopefully this clears him up. He has a vet appointment next Saturday with a new vet that specializes in cats only.
