Giving away a helpful homemade wooden screen that can cover the lower shelf of a cabinet or closet to allow a cat to use the litter box, without litter spraying, or dogs or toddlers getting in! We have used it in the past to block the cat's food from the dog as well, and put it in the window to make a cat door. It has a hinge in the middle, and the 2 panels slide out to reposition as needed.
DM with questions!
