(Oster) It’s a well known fact that pets do not like aluminum foil. The Whoa Buddy! Blanket contains one side that mimics the sound and feel of aluminum foil. This acts as a natural deterrent for your dog or cat, helping you to keep them off your furniture and counter tops or like a barrier between rooms. When not in use, the blanket folds down into a soft, attractive fleece. Spot clean only.
