My neighbor does not have internet access so I thought I would ask for her. Her 5 year old cat is flinging litter all over the place. Makes no difference what brand, used or fresh litter, or type of box. She has multiple cats each with their own box so she can't be sweeping up litter all over. The boxes range from kitten size to the largest for adult. I looked online and can't find the exact name. Isn't there a mat to place under the boxes or would that help at all? Cat was just at the vets going to same place I took Phantom and the cat is healthy. No emergency just want some information to relay back to her. And thank you.
