Comforting heat and soothing cold do wonders for achy joints, sprains and strains – for you and for your four-footed pals. The Pet Bed Hot-N-Cold Pack makes it easy and safe to treat your pet to hot and cold therapeutic care. Just pop the non-toxic gel pack into the microwave or freezer to heat or cool. Then slip it into the insulated, chew- and scratch-resistant pocket, and place it inside or under your pet's bed. Also ideal for cooling off on a simmering summer day and taking the chill off after a hard winter hunt.
