Cryptokitties is possible because of ERC 721, which allows for unique tokens to represent individual assets (having an indivisible kitty with its own dna). As far as I'm aware, NEO doesn't yet provide the ability to create individualized tokens that can be stored on the blockchain in a similar way.

ERC 721 just an API standard for non-fungible assets. There's nothing special on inherent to Ethereum that makes Cryptokitties possible.

You can totally build something Cryptokitties with NEO -- the only difference is that because there isn't a standard, there isn't a third-party marketplace for these assets. (i.e., there's nothing inherent about NEO that prevents something like Cryptokitties from being built.)
