Red Heart, Pulsing Heartbeat is soothing and comforting to lonely, afraid, and nervous dogs who don't like to be left behind while their humans are gone. The batteries last up to two weeks of 24/7 use on just one set of AAA alkaline batteries (batteries not included), great for kittens and puppies who use our Franny the Pet Nanny or Mini Franny at night, nap time, or home alone. (mini screwdriver included with heart)
