We have cats, just like you. We recognized that our cats love the boxes their toys come in better than the toys themselves. We thought Why fight it? and set out to build a better box. Catty Stacks are the best boxes you can buy! (Say that 5 times fast.) Our proprietary cardboard is made just for us, just for this purpose. Think fold-able wood, but just as eco-friendly as regular cardboard.
Great for other small pets too, like bunnies and dogs.
