Aspen Pet® Self-Warming Bolster Kennel Mats are constructed using space
blanket technology. A Mylar interior layer creates a safe, convenient way for
cats or dogs to stay warmer by reflecting a pet's body heat and retaining that
radiated body heat. No electricity is required. Made with contrasting corduroy
and supple comfy faux lambswool with plush sides for pets that like to burrow.
Also will fit into a 24" plastic or wire kennel to provide extra comfort.
Anti-skid fabric on the bottom. Lightweight for easy transport makes it perfect
for vacations and road trips. Machine washable.
