my family owns a 6f cat that was pretty normal and nice but lately strange behavior has been occurring and my mom wants to get rid of her now she used to always use her litter box casually but now she wouldn’t get near it she pees and defecats almost everywhere in the closet on the carpet behind the fridge it is starting to annoy my mother and the smell is horrible how do I fix this or get her used to her litter box again? I dont want to lose her any tips on how to convince my mom to let her stay longer?
