The idea in this design of the final project was to make a sleeve to cover the existing mat in the bottom of the crate. I added padding as well. The idea is that if the sleeve was tight enough, he wouldn’t be able to get his teeth around it and because it was around the existing mat, it would take up the entire space of the crate and he wouldn’t be able to move it around or get his mouth on the edge of it. Also, I made it removable so that if it were to get messy, I could easily take it off and clean it in the clothes washer.
I think he likes it!
