Kitty Slash sounds like an attack name or a game title, not a monster name. Reversing it to Slash Kitty makes it more like a name for a kitty that slashes.
The pixelling looks good, but the pose is dull. For enemies, I think it's good to start with an attack or movement pose, since those are what the player will see most often. The idle should probably be a pose that can lead easily into one of those.
