I love this design, could become my favorite Pokémon! Fennekin-line was the first step away from the fire/fighting starters but I didn't like how they made it look female as if that's the only way to not look related to fighting.
I'm pretty certain with having a cat now there is little to no chance we'll get a physical fighting-type-looking final evolution. Cats are known to be elegant after all! And that's how Litten looks to me. Clever, sneaky, cute. Because of it's color pattern and the cold expression in it's eyes I think it will be fire/dark and I can imagine it being special. Could be physical and using claws with dark energy. I like cats in general, so don't know about you but my hopes are really high for this starter!
