Yep, Hydroaxe - Kitty ended up with her name as she was a stray 17+ years ago and that was the only thing she'd answer to - so she pretty much named herself.
And - Sicy - to answer your question...yes and no. I had such great hopes of Lucky hanging out with the family, but at times wondered if it'd ever happen. I think when we got Charm - it really brought Lucky out of her shell (as Kitty still isn't too thrilled to have these other 2 feline creatures around).
But I'm soooo happy she's so friendly now. She'll still get a bit edgy from time to time, but it's shortlived and she gets back into the swing of things. She also enjoys laying in our laps - but only for a few minutes and then she'll go away for a second and be right back - it's like she doesn't want to "give in" to us humans too much.
