Good fn grief.....shut the door and let the cats outside! She has the money, get the room cleaned! Build a room for them if you don’t want them out.
I really hope she doesn’t want me to feel sorry for her...idiot.
Other than the outside idea, I agree. I am amazed at the number of people who have several cats and only 1 or 2 litter boxes. If you don't have at least as many litter boxes as you have cats, you are flirting with disaster. Especially if there is stress in the house, which is sounds like there is with Mayim.
