Review on 🐱 Kitty Sift Disposable Cat Litter Box, Large Size 13.8 x 17.8 x 4 inches (Pack of 12) - Eco-Friendly, Plastic Free, Made from 100% Post Consumer Waste Recycled Cardboard by Joyce Keesling

I tried the Kitty Sift litter box and loved it - in my review I said it was good for travel. When I ordered it, I didn't realize that they were only part of the system and not the grid layers above. But my original assessment still stands. They're great for travel - lightweight and disposable, but durable enough to be reused, at least for a short time. (The full Kitty Sift system soaked up some urine after a while when I used it.) If you're buying these for travel or general use, you'll need a scoop, but that doesn't seem like a huge inconvenience to me. , as I would still prefer a scoop over a kitty sift system.
