Help finding a name

In my book my character is a beast-like boy. He has sharp golden eyes and black hair, he is lean and strong. He isn't human, but he isn't technically a monster either.

I have a couple of names for him but I like to have a lot of options. I was thinking of have 'kat' somewhere in his name, since he is cat-like, but I don't care if you don't do that.

Here's the names I've come up with:

Kaizen
Katsu
Katsumi
Laethyn
Nezera
Zehel

Like I said, I like to have a lot of options when it comes to character names. After all what names I don't choose I will save for my next character.

Thank you for your help. :)
