The Crate Mat covers are specially designed for Kangaroo Crate Mats. its sizes are made to fit in all Australian dog crates (Across all manufacturers). It’s made of RipStop fabric which is woven with coarse strong warp and filling yarns at intervals so that tears will not spread. While the cover itself is water-resistant, we have added an additional water-resistant liner to protect the memory foam from liquid damage. The crate mat comes with securing hook and velcro straps so that it can be tightly secured to the crate, and it will deter the dogs from taking it out of the crate or chewing it.
