After three months in residence, the New Kids are definitely two distinct personalities (I almost typed purrsonalities, but decided to spare you the pun).
Sheba is a little pistol; she climbs the curtains, pulls flowers out of vases and scatters them on the tabletop, knocks over pot plants (she smashed Petunia), chews holes in the kitty litter bags, and ambushes the dogs. She also has decided that Reserve Cat is all hat and no trousers, and torments him whenever she gets a chance.
Sheba's favorite pastime is to dash at top speed from the kitchen to the living room without touching the floor. I have no doubt that when summer comes and we start letting them outside, she's going to be the one dragging home rabbits twice her size and still living.
Minnie is whiny, clingy, greedy, and a scaredy-cat. Having said that -- she likes to cuddle and hasn't broken anything.
