In-Ground Cat Fence - Create Safe Outdoor Roaming Zones - Waterproof & Battery-Operated Collar - Covers Up to 1/3 Acre with 500 ft of Wire - for Cats Older Than 6 Months, Weighing Over 6 lbs

The PetSafe In-Ground Cat Fence allows cats the freedom to be outside within customized boundaries set by the pet parent. A radio signal travels through a buried wire, marking the boundaries you wish to set for our cat. Your cat wears a receiver collar with contact points that touch her neck. The receiver collar detects the signal at the boundary. As your cat approaches the boundary, the receiver issues a warning tone. If she proceeds further, she receives a safe but startling static correction. While harmless, the correction will persuade her to stay in the established containment area. With 4 levels of static correction plus a tone only mode, you will be able to select the right level for your cat. The collar strap includes a stretch section designed for cat's safety.
