One ScatMat with use instructions. Requires one 9v battery, not included. I ordered a Scat Mat about a month ago to cure our poodle of the habit of using the carpet for a bathroom. In just two days my headaches are over. It sure worked in our situation and my only regret is that I never found out about it sooner.
