Since I got help here for my cat, thought I would ask about my mom's cat. Before anybody says anything, NO, I am not getting rid of the cat. Mom's cat is about 18. He's never used a litter box,...
I have several dogs and over the years have bought some of the dog beds that contain redwood chips. I have had to throw all of them out. My cat likes the redwood beds better than the litter box. You might buy some redwood landscaping chips and try some of them in the litter box with the litter. If it doesn't work you will only be out the cost of the redwood chips.
