The larval form of cats.

Kittens have a satanic power to enchant the females of the human species. While the level-headed male will envision the day the kitten becomes a cat, the females somehow believe that the kitten will remain a kitten forever. This is the genesis of the hatred for cats that the majority of the male section of the human species has.

Puppies will grow up to be dogs, but whatever traits drew you to the puppy (trust, loyalty, stupidity, etc.) will only grow stronger with age.

The kitten will look at you one day, when it becomes a cat, and you will be clearly able to hear a fuck you deftly hidden just underneath the meow.
