PetSafe Extra Wire & Flag Kit

I moved from 10 acres in the county to a small unfenced yard next to a busy highway about 10 months ago (renting). My two cats (ages 4 and 2) were used to freely roaming the countryside. I bought the PetSafe electronic fence and it taught my cats their boundaries with only 2 ZAPs each. The zap does not kill them, but it sure as heck does startle them! The youngest cat did a back flip and a half the first time he got it. After that, the tone keeps them with in the boundary. They never wore a collar before, but got used to it real fast. I love my cats and was worried sick about them going onto the highway and being killed, but this product does what it says and my cats are still living today. I replaced batteries once in 10 months. Great Product, a real God send. Rent an "edger" from home improvement store for fast and easy digging, and read the directions well on how to install. It seemed complicated at the time, but looking back, it really was simple. As far as training the cats goes...I got a harness and leash, and they would just plop over and lie there when I put it on them. It was quite comical-they would just plop over and lie still. If I got the cats on their feet, they dug in and would not move...I had to pull and drag them. I felt it cruel to drag them across the yard to the flags while they were laying on their side only to quickly drag them back away from flags while they were laying on their side. I put up the flags and the cats quickly figured their boundaries out. I supervised them outside for a good week or so, to make sure they did not zip through the boundary during a zap. So don't be dismayed about training your cats, it can be done by letting them figure it out on their own. As I said, they each got 2 different zaps within the first couple days, and that was that. Cats are smart. But by all means, try the training out first. Your cats may be more amenable to the leash. From a happy customer and my 2, still living on the side of the busy highway, cats!
