Practically every night when I go to bed, I will call out to Jumper and the others, "lets go to bed, cats". He comes running upon the bed, and instead of laying down for the night, he gets wired for "220 volts" and begins a show of antics that makes me laugh. Chasing his tail, and hind legs, doing flips, moving at lightening speed, he attacks anything that moves including my hands and feet under the covers. This "clowning" lasts for about 15 minutes every night. I don't know if he is happy that I'm in the bed or whether he is excited because of the approaching sleeptime for me and my furkids. Any ideas?
