Your little ones must be "morning kitties" unlike mine who, after they eat, are actually pretty lazy. My boys don't have too many of those dashing/racing/chasing marathon events any more. I guess they are maturing! Sometimes when I come home from work I see little tufts of fur on the carpet and I know they got into one of their rolling matches. It's so funny to watch them go around and around like a big orange and white ball of fluff. Then out of the blue they stop and groom themselves!
