So my boyfriend's mother and her husband separated sometime last year and he finally moved off somewhere and dumped all four of his cats on her to take care of, in addition to the two she already had. They all know each other so other than the fact that there are five males and one little female cat and they rape the shit out of her, they get along.

But all of a sudden they've just stopped using the litterbox. It gets cleaned daily. They used it just fine for the first two weeks, but now they're shitting and pissing all over the house with the exception of two of them. Last night one of them hopped up on the couch, started meowing in a really weird tone and pissed all over the pillow.

What the fuck is going on?

Pic isn't them, just random shit from google.
