What do you all use for crate mats? I realized that our current fleecy ones, that I really liked, are a bit too hole-y for me to want to keep using them for much longer. I'm leaning toward getting fleece mats again, but figured I'd see if there are any new options out there that I should consider. They do need to be durable *and* either easily washable or waterproof (since Z is crated overnight and during the day when unsupervised due to incontinence) and reasonably priced as I might go ahead and buy one for each dog's crate. The car crates have rubber backed bathmats, which work marvelously, but I want something a bit more cushy for the other crates since a couple of the dogs have calluses on their elbows I'm trying to minimize.
