When we lived in a house with a pool, the cats hung out around it constantly. They discovered that they could go up the ladder and slide down, and jump off at the curve before they went in the water. Occasionally one would miss, hit the water, and have to swim to the other end to the steps. Fred was sleeping on the diving board, sunning his tummy, and rolled off in his sleep. I was glad I was there, I fished him out with the pool net. Even the neighbor's cats like hanging out there, and they were always falling in. Silly creatures!
