He's adorable. All four of my cats love to play. Storm is 7 and is starting to slow down more but he'll still race around the house and play chase every now and then. Sunny will be 3 in late August and he loves to play and run around. Cirrus just turned 1 in June and also loves to play. Sky is also 1 and still acts like a big kitten. Everything is a toy to him. I think that it will take a long time before Sky slows down. I love cats that are playful and full of energy except when I'm trying to sleep. It sounds like Cubby has a great personality.
