Q. My cat just peed on my bfs & my wall in our apartment. She has never done this before. Could it possibly be cause her litter box had stuff?
A. Litter box issues can be caused by many things: marking territory, behavioral, because their box is full/dirty/don't like the type of litter or style of box, etc but you should always rule out a medical reason first, before exploring these other triggers. Cats are prone to urinary crystals, bladder stones and UTI. I would have her checked by the vet to rule this out before considering why else she may be doing this.
