The simplest things provide such amusement to the two tom-kittens. A piece of orange plastic baling twine with knots at the ends is making Pangur Bán leap and dance in the bed flinging himself into the air. The boys carry it around to where they want to play with it. Sometimes each one operates one end of it, tug of war, or one end on the bed and the other end off it - these are some of the games. A kitten just went crashing off the bed to the floor with a bump. Now dancing on top of Janet’s lap while she is trying to read in bed.
