Baby, it’s cold outside! But what to do if your furbabies are saying “Brrr” when they’re indoors?

Mischa Barton swaddles her two pooches in their own heating mats from Pet-Zzz-Pad, a warmer that heats up to 102 degrees. It activates when it feels weight, molds to an animal’s body and surrounds with toastiness.

“You’ll often notice dogs with muscle or joint pain seeking out sun spots,” says Christopher Hallihan, DVM, in a press release. “You may also want to use it for dogs that shiver, as well as puppies and kittens that need extra warmth.”

The Pet-Zzz-Pad ($19.99) comes in three sizes – 12-in., 16-in. and 20-in. pads – depending on your pet’s size. It includes a fleece cover that’s machine-washable and that can be embroidered with your pet’s name. Find the warmers on petzzzpad.com.
