My male cat continually sprays on everything, i.e., under bed, under dresser, on couch, blakets and on me when I don't get up in the morning when he starts to cry. He's been to the vet and they say there is nothing wrong with him. I do notice that, even when he does use the litter pan, he doesn't squart - he stands. Therefore, when he does that under the bed it hits the box springs. What can I do to provent him from doing this? He is a Ragdoll and we have four other cats. Help!!
