Make sure your cat behaves as if you were standing right there. The PetSafe Wireless Indoor Cat Barrier is safe, easy to set up and very effective.
Just place the small, disk-shaped transmitter (about the size of a Frisbee) near the area you want to protect. Then adjust the range from as little as 2 feet to up to 10 feet.
When your pet gets near the signal a warning beep sounds on the receiver/collar. If he continues to approach the protected area, a mild correction is given. You can increase or decrease the correction to meet your cat's training needs.
You can protect multiple areas and cats with additional transmitters or collars. The receiver/collar is light and durable and specifically designed for cats with an elastic safety strip that will stretch in those instances where your cat is exploring in a tight place.
