Hello! I am a new member and wanted to see what advise I can get about my male cat Oliver who has been spraying a lot lately. He is doing well by at least spraying inside the litter box, but it leaks out onto the floor and into the baseboard of the wall. I have an odor neautralizer that I have sprayed where it has soaked into the baseboard, but it still smells in there. And I can't figure out any tricks to keep the spray from coming out onto the floor. The little box has a cover - and it is a large size box. Any suggestions? Thank you so much for your help.
