Kah-ti-rah I realize that there is NO WAY this is the correct pronunciation, but I'm one of those people who glances and then jumps to pronunciation so I thought I'd be honest about what I thought is was. Kah-ti-rah sounds futuristic as you suggeted. I find Kay-trah (as others have pronounced it) sort of hard to say, sort of forced rather than smooth off the tongue. Curious if you are thinking boy or girl for this name?
