Once cats start using a garden bed or a child's sandbox as a litter box, it can be very difficult to get them to stop.
Using a heat-sensor trigger, CatStop emits a burst of ultrasonic sound to repel cats that come within a localized area. The heat sensor covers about 300 sq.ft. in an 105° arc in front of the unit, with a range of about 20'. The noise frequency sweeps from 21 to 25 KHz, a range audible to cats but not to humans. At 124 decibels, it will startle a cat, scaring it away from the area.
Keyhole slots allow fence or wall mounting, or it can be set in the ground using the included stake. (Some white cats, older cats and exotic breeds cannot hear higher frequencies and may not be affected.) 9V battery not included. For outdoor use only. Weatherproof ABS housing.
