Both of mine started off when my wife "fostercared" for a couple kittens from the Animal Protective League. Alot has happened during the past 16 to 17 years, but the cats are still here. They still act like a couple of kittens, playing and fighting with each other. They even swat at my son's dog when he's over at the house. I keep expecting to find one laid out on the floor when I get home from work but they've thus far managed to survive.
