Kittyful Infection

An outbreak starting in tokyo takes the world by storm. Aliens, which nobody knows have done this, engineered a virus to turn humanity into pliable pets. When the entire world has turned into dumb kitties, the aliens will arrive, and easily conquer the planet, making humans their sex slaves/pets. Most people assume that the virus was caused by a genetic engineering incident before alien arrival. The virus first presents as an unbeatable, undying fever, that leaves the host in a thick mental fog, happy, docile, and cutesy. Instincts to meow, giggle, and purr, chase lasers, catch mice, stretch, all push themselves to the forefront of a shrinking, very ditzy mind, eventually leading to the fever dying. Eventually, the host will feminize to an extreme degree as their hormones fall out of whack. They will grow shorter, weaker, their boobs and butt growing out to a decent degree as well, possibly developing heterochromia, as their ears will transition to the top of their head and become fluffy and cat like. They will also grow a cat tail. Their vocabulary will degrade significantly, causing them to need to spell out words, and forgetting very specific, advanced words. The virus will fight back HARD against any research or intelligence. The sickness is fast-acting (taking two days to reach previously stated effects), and transmutes mainly through touch and the initial cough during the fever. The virus won't stop there though. Eventually, the host will develop a heat cycle and become incredibly horny for a day out of the week, get uncomfortable in less cutesy clothing, and develop an unstoppable speech impediment that forces them to nya in places where n's and vowels are close together. As the virus continues mutating the host slowly, this is AFTER the previous steps have taken place, and ONLY AFTER the previous steps have taken place, their hands and feet will plump up into unusable, cute paws, as will their feet. They will grow fur across their body, and they will additionally grow a snout that's very adept at sensing musk, with a cute kitty nose. Their legs will additionally become digitigrade.

All throughout this, the host will lose their personality. They will start hating smart things, loving simple things. They will also occasionally drool.

The host will continue to get dumber and dumber and dumber over time, as their brain shrinks permanently, they lose resistance.

The host wont inherit cat-like traits that lead to distraction from simple things. This distraction should naturally occur from their decreasing brainpower. When the host is decently into their infection, they will think things like "Driving a car? Kitties don't do that." or "Working? Kitties don't do that."

The aliens are tall, strong humanoids with catlike traits, although very intelligent. Aliens can breed humans who have gotten infected to the fullest stage to produce more alien offspring, or more kitties, with a 50/50 chance. The aliens speak perfectly and can talk in every human language. They want humanity to be dumb, any "humans" who show signs of still being smart are corrected. All intelligence removed. They will gaslight humans, saying its good to be dumb, good to be horny, good to meow. They love dumb pets, more than anything. By the time the aliens arrive, everyone who is a kitty is female, no matter what. All kitties are considered lesser than the aliens and are breeding livestock/pets, and may be reassigned to different roles accordingly. Sometimes aliens will abduct the humans to take them back to their world, or the humans will stay on earth as the world is rapidly recolonized. Aliens will talk down to humans, hardly ever lifting them up other than calling them "cute". The aliens will never say that the humans are perfect, or that the humans are great, just that they're good dumb kitties who fulfill their purpose of being good dumb kitties. Aliens do not want the kitties to do research or think smart things. They will ALWAYS correct such behavior, saying things as "That needs to be fixed". Kitties who like doing smart things must be corrected. Kitties who like doing dumb things are what is desired. Researching, intelligent kitties must be corrected. Aliens will do hypnosis upon kitties. When kitties have smart things they like, the aliens will say they dont, and the kitties brain will rewrite itself instantly. For instance: a kitty might say "I like to do research" and then the alien will say "No you dont. You like to breed and be emptyheaded." then all enjoyment of research is instantly purged from the kitty's mind. Anything the aliens say that the kitty wants under hypnosis, will immediately be etched into their mind.
