I am selling this because I no longer need it at my parents' house. Quoted from the website below: Target Animals: Cats and Dogs Features: ● This is a safe and effective training sheet for pets to prevent mischief. ● The weak stimulation generated when the pet touches the sheet teaches them to avoid restricted areas. (It's a weak electrical current, like static electricity, that is safe for pets.) ● By learning to leave the area and repeating the positive experience of being praised, the effect of preventing mischief is enhanced. ● It can be used in places where you don't want them to make a mess or enter, such as for toilet training, marking behavior, doorways to kitchens and bedrooms, and around furniture and curtains. ● It has a warning sound when passed through and is a safety specification. Also, it can be used for a long time (about 15 days) on a single charge. Included Accessories: ● Power cord (USB-A to USB-C), Tester ※ USB power adapter is not included.
