Both kittens show strong arboreal tendencies. Sputnik, pictured here, is much more adept at it, being lighter and more agile. However, ever since he fell into a hot bath, which probably burned him a bit, poor thing, he has been afraid of water. He therefore approaches the pond with great caution. Telstar, on the other hand, is aquatic as well as arboreal. He's a big fan of pond-skating, which he's had ample opportunity to indulge in since the pond has been frozen since early December. He never seems to get any better at it, thereby demonstrating that practice doesn't make perfect.
