Hi there. Please help I am out of options. My 3 year old male cat Sigmund (siggy) has completely stopped peeing in his litterbox. He is fixed and has never had this problem until about 2 months ago. We had recently moved in with my fiance who does have a dog about 3 months before this began. He was fine for those 3 months and has cohabitated with the dog very well. I took him to the vet who did say he has crystals in his urine and that we should begin medicated food (hills prescription urinary care) which we begin a bit over a month ago. It hasn't helped at all and he is still refusing to pee in his litterbox. He does still use them to poop, but he pees anywhere he feels like it. He has three uncovered litterboxes, one on each level of the house. I have tried different all different litters and am currently using a "cat attract" litter and it hasn't helped. I have also started using feliaway plug in stress relievers in cast he was doing it out of anxiety. He doesn't act like he is stressed out at all. He cuddles and plays and eats and drinks regularly. He isn't peeing in one specific spot either its all over our basement, on our clothes, on our bed it really doesn't matter. I don't know if this is still a problem with the medical issue he has or if it is behavioral at this point. If anyone has any advice I would really appreciate it. I am so very frustrated because I truly have never met a better, more sweet boy in my life and I love him so much. I just don't know what to do.
