Thanks a lot everyone! Ebony still hasn't settled down yet, in between her spouts of vigourous wheel-running, she entertains herself by jumping on her sisters who are trying to sleep! Needless to say, they squeak a lot at her

Ebony's also the bravest one, I've had my hand in the cage for a few minutes and she's quite happy to jump all over it, whereas Twilight and Nightshade need a little coaxing.

And, of course, Tia is pretty horrified!!! I took her into my brother's room so she could just look at them, and she froze, then gave me this look which clearly said, ' Oh my gosh, HOW COULD YOU?' She's giving me the cold shoulder a little and gnaws my knuckles as if she's teaching me a lesson. I'm sure she'll come round in time.

Oh, I also forgot to mention how to tell them apart, other than their personalities. Twilight has one white front paw and a smudge of white on her nose and under her chin. Ebony's front paws are both half-white and she has a lot more white under her chin. Nightshade has one front paw half-white, whilst the other paw has an unusual circle-like pattern of white, and she has a perfect line of white under her chin.
