when I read all the glowing reviews on this self-heating soft bed, I bought it for my little dog, saying he would be warm in this basket. But alas it is not doing case. Maybe this winter will appreciate it more ........ This basket is made with a very soft cloth (suede style) inside the sleeping, edges are reinforced. This pale green should be well messy! It is anti slip. But it's still a bit expensive. Well a few months have passed since the purchase of the basket, and my dog never leaves his cozy bed. Really perfect for a small chien.Je do not regret my purchase.
