After a bunch of nuclear power-plants all around the world exploded due to some dumb mistakes, radiation caused mutations in just about all the animals and some plants on planet earth. Especially cats. Now cats are the lifeform above all lifeforms, because for some strange reason, radiation had a veryyy pronounced effect on cats. Now dead-set on vengance, cats are out to get humans for making embarassing dank memes of cats and overall setting dogs as the superior species. This will be really endangering the humankind. Plus the fact that now every single animal on earth is sentient, stronger, and sometimes smarter than humans, humans are now on the bottom of the food-chain.
