I've always been puzzled by the way most people name their cats. It's perfectly normal, but naming a cat after a person, or giving them a full name, or a human name, never crosses my mind when I get a new cat. In fact I never name the cat until after I've come to fully understand what they'll definitely respond to. In other words, I let the cats choose their names.

For instance it took an entire month for us to name Specky. Eventually we decided to name her off the speckles on her coat, which she responds to just fine.
Woo took even longer because it was so difficult to get him to like us. Eventually it came down to, whenever I said "woooooooooooooooo" he'd actually come towards me because that was the hint of food.

Zipper was named after the weird sound he made when he mawed, Baby was named for the fact that she was of a single-kitten litter, Missy as because she was a priss, and Alfalfa for the mark on her forehead.
