You’ve been warned. At least there aren’t any pictures.
Most experts say there should be one more litter box than you have cats. I’ve almost never done that and, fortunately, I’ve never had a problem. I’ve been blessed with tolerant cats. But I do increase the number when there are additional cats in residence. Right now, with five cats, there’s one in the bedroom, one in the den, one in the bathroom and I’ve had to put a litter box in the living room. It’s out of sight, but still.
I’ve also read that many cats will urinate in one litter box and defecate in another. Mine have never really done that, either.
Recently though, someone has decided to “assign” the boxes. Ok, whatever. But why, oh why, have they decided that the living room box is the one for pooping!! Pee-ew.
