If you are having a problem with cats, foxes and even rabbits in your garden then the Pest XT ultrasonic battery powered cat repeller will provide you with the perfect solution. Completely harmless, the repeller senses larger mammals and emits a high frequency sound that they immediately find uncomfortable and so avoid your garden. The device does not affect birds, so if you also want to keep your bird feeding station free from feline predators then this is perfect for you too! Features: Covering a large area, the repeller operates using a PIR motion sensor with a 110 degree detection arc and will sense animals up to 26 feet away, giving you a total unobstructed working area of 286 sq ft (70 sq m). Simply position it in the ground using the stake provided, or fix it to a wall or fence to cover the maximum area Dimensions: L109 x W63 x H147mm | Weight: 203.4g | 4 x AA batteries (not included) | Frequency: 19-45KHz | Area: 70m² | Coverage: 8 metres, 110 degrees Specifications: Dimensions
