Well, the ultrasound showed no stones but we are still waiting for the urine result. He had a shot of antibiotic as well. I covered the bed with a shower curtain. Yesterday was okay but today he peed right on the curtain. It really puzzles me. He is a very smart cat, not bullied, very loved. I even got 3 more new litter boxes. The vet had not behavioral advice.... he is a new vet, my old one retired.
I can't lock him up, he is very alert, social and playful, it would be very hard for him. And he does use the litter boxes, I saw him there. He just randomly decides to pee on my bed. Why???
