Disturbing Trends in Kitten Behaviour

OK, the kittens, Jerome/Hockey-Sock and Sophie are downstairs because when I type, Hockey plays with the curser. Now they are taking running leaps against the basement door, crashing and banging and crying. They need a home. Not my home, because Coco is wildly jealous of them and has taken to yowling, something she has never done before. I am turning into a completely cat-absorbed person. Help!
