Just adjust the range from as little as 2 feet to up to 10 feet. Your pet then wears the same receiver that is used for Underground Electronic Cat Fence. If you have more than one cat, or more than one area to protect, you can do so by ordering additional Indoor Cat Barrier's or additional cat fence collars and cat fence transmitters.
When your pet gets near the signal a warning beep sounds on the receiver. If he continues to approach the protected area, a mild correction is given. The PetSafe Wireless Cat Fence can be used for as many pets as you have! Each pet needs to wear a receiver collar which can be purchased separately.
With the PetSafe Indoor Cat Barrier you can increase or decrease the correction to meet your cat's training needs. The PetSafe Wireless; Indoor Cat Barrier allows you to contain cats of all sizes within the same fence. The Indoor Cat Barrier can be used with several cats with the purchase of additional receiver collars. The receiver is light and durable - perfect for a older or smaller cat, and when set at a correction level 4, strong enough for the largest and most stubborn cat.
The specially designed Cat Safety Collar features Nylon web construction with an elastic safety strip that will stretch in those instances where your cat is exploring in a tight place.
