Why is my cat suddenly refusing to use its litter box?

Cats refuse their litter box for several reasons. The reason why your cat chooses not to use the litter box depends on where they are opting to go instead. Cats who start to relieve themselves just outside the litter box are trying to signal you to clean the box. No pet likes to step in their own waste so perhaps the litter box is too full for your cat to comfortably “go” in. If your cat is seemingly having accidents around the entire house, they may have a urinary tract infection and will need immediate veterinary assistance. If you are unsure why your cat is refusing their litter box, it’s best to schedule a veterinary exam to be sure the problem isn’t caused by a serious medical issue.
