We have two cats who share a little box. They have shared this little box no problem for nearly a year (both cats are nearly a year old). Lately, the male has been leaving nasties on the floor in front of the litter box. I caught him doing it once and punished him for it that time. I don't want to punish him for it if I don't catch him "red handed" since he may not understand the punishment. I have no idea what could be causing this. We give both cats equal and LOTS of attention and play with them all the time. The litter box is always clean and they always have fresh food and water.
Help??
