Helps train your pet indoors. The spray contains a harmless substance that cats and dogs find unpleasant, and your pets are thus discouraged from scratching or chewing anything that is sprayed with Pet Behave. Popular with home-owners for use on household furnishings, woodwork, doors, curtains, baskets, carpets, rugs, slippers, etc. Repeat the spraying every 2 to 3 days, until your pet has learned to leave the desired item alone.
