So cat lovers, riddle me this...

[fleur-de-lisa]

1. Vets recommend one litter box per cat, plus one extra.

The boxes should be in multiple locations around the house, not all together in the same spot.

If a cat isn't using the box, she needs a vet visit to make sure there isn't a medical issue. I had a cat who lived to be 18. He would often poop on the bed. We found out that he had a version of kitty IBS. Medication resolved the issue.

If there is no medical issue but the problem persists, make sure the boxes are located so that the cat can access it from more than one direction. If the box is in a tiny room (closet or bathroom), the cat may feel trapped while using it, especially if another cat likes to attack. Leaving the box in an open room, adjacent to a wall, may help.
