The cursed cat

The timeline takes place in the far future where war had influenced scientists to make killing powered machines out of cats(not actual machines).They placed elemental powers in they're blood so the cats could have a power of fire,ice,water,lightning, air, or even the forgotten shadow power. But not all get a power some grow wings, some have the power of shapeshifting, and some lose their mind in the process causing them to lose their memory and their feelings.
