Review on 🐱 PetSafe In-Ground Cat Fence: Waterproof, Tone & Static Correction, Safe Stretch-Section Collar for Cats 6 lb & Above by Shannon Sims

Best money I've ever spent on my cats' peace of mind. I lost two to coyotes, but now there's an invisible wire attached to the base of our wooden fence. All cats stay within the perimeter. I wish I had found this sooner. There was some trial and error that got everything working properly. At first the collar dangled a little around the cat's neck. We also ran the wire straight over the top of the fence. When they got up, he just squeaked and they flew over the fence. It now works up and down the loop so it warns them when they get close to the perimeter. We had to tighten the collars to make sure they worked properly. Now it works like clockwork :)
