Thanks for replying. I do have two covered litter boxes, one in each bathroom, I made sure to get another when I got the 2nd cat. My 2 year old (Binks) uses the 7 month olds (Chester) and his own. Chester uses the new one. I could put a litter box in the Florida room, but I don't want one there permanently, am afraid he will train to only want it there. Could Binks be bullying Chester, he does seem to like to stand right outside the box while Chester goes to the bathroom and rush in there once Chester is done! I try to tell Binks no, and move him away from the box while Chester is in there, is that the right thing to do? I have never had two cats before or lived with two cats before.
