My oldest cat, Snowball, is 15 years old and she has always been very agile. Because of her age, I can't help wondering from time to time how much longer she will be with us, but she has never shown signs of any infirmity, until today. It always seems like Snowball never changes or ages. I keep their food and water on the counter because of the dogs. Snowball attempted to jump from the counter to the kitchen table, which is only about a foot and a half; she missed and fell to the floor! I've never seen her miss before. I picked her up and cuddled her and sympathized and she seemed to be ok. But, for me, it was one of those compelling moments that you never forget. I do keep a chair there so they can get up to the counter easily, but that was really for Spooky who is overweight more than Snowball.
