Modkat top-entry litter boxes keep litter spray to a minimum, and even though my cats prefer a more traditional box when given the option, they do use the Modkat. Type A Modkat Liners are helpful when it comes time to replace an entire box worth of litter: lift out of the box with the built in handles and directly into the trash. However, the replacements never fit the box as well as the original liner that came with the box (possibly because of how the replacements are folded, rubber-banded, and packed for shipping), and they tend to leak urine through the seams. Overall a solid product, and more or less required for the top-entry Modkat boxes, but definite room for improvement.
