Great for the hot summer months, pets can cool off easily with this comfortable Medium Pet Cooling Gel Mat featuring a tough, durable mat that contains a non-toxic cooling gel that doesn't require water or refrigeration to activate. This self-cooling mat works by absorbing body heat and dissipating it back into the air. The mat is cool to the touch but cools further with the pressure of your pet laying on it. This is better for your pet than laying on a cool surface because it gradually cools its body temperature. The surface can be simply wiped clean with a damp cloth. Measures approximately 15" x 19". Comes packaged in a hanging box.
