I love the fact that these boxes have high backs, are seamless and have changeable liners. They are the best!
For small spaces, ie apartments or condos, Modkat litter boxes are the only way to go. We actually get compliments on our kitty litter area and how nice it looks. I'll never go back to open litter boxes.
Modkat Liners - Type A (3-Pack)
We have 3 big cats and 3 of the Modcat flip top litter boxes throughout the housae. It's been several years since we purchased them with the liners and love them. Tall enough to keep the litter in.
