PS. The morning after I first put our solar blanket on our pool, I had a scare! One of our cats walked on top of it and was sitting out in the middle of our pool on it! Mind you - we have friends who had a cat get in their pool and it tore up the liner trying to get out, so you know what was going through my mind! The blanket didn't even give as I called her over to the side as she walked on it. I took her off- then swatted her and yelled at her to get away from the pool, lol. Last time I seen her on it.
