Mary noticed the human drawer and it had all kinds of different things. She could increase her bust size, or make herself taller! But the big vial in the human drawer (or at least the first one she notices) just says human. That must be the one that can change me back to normal, she thought. Then her cat walked into the room.
"Hmm...I wonder."
She grabbed a small bowl and poured the entire human vial into it and put the bowl on the floor. Once she placed the human vial back into the case, it refilled itself.
"Here Missy, come try this."
The cat hesitated, but started drinking the contents. It must have delicious, because she licked it up fast and soon it was gone. The cat remained unchanged.
"I should have figured. Nothing like this is even possible." Mary said. But then she noticed something about Missy.
Missy's back legs were growing. As her the legs were growing, her back paws were as well, changing from cat paws into a bipedal human feet! The change continued up Missy's legs and her fur receded and it started to lift her off the ground. Missy meowed in panic, but she didn't move.
Her knees shifted the opposite way so she could walk like a human. As the transformation got to her tail, Mary watched it recede into her backside. Missy's ass also started to plump. Soon it no longer had fur and Missy's hips expanded. Missy's vagina also relocated to her front and became a bigger human pussy (no pun intended). Missy had the bottom half of a human and was standing up on two legs.
The transformation continued to her torso as she her rows of teats disappeared and a belly button formed. Her hands went from paws to hands. Her front legs became human arms. The transformation reached her chest and the only teats remaining started to push out. As the fur receded, Mary noticed the nipples were more human and soon Missy had a beautiful rack! Mary was kinda of jealous. She was jealous her cat has bigger tits than her!
Missy meowing this whole time, soon gained vocal cords and the meowing turned into human moaning. Her head was the last thing to change. It grew to twice its size and hair (the same black color her fur use to be) cascaded down her head. The remaining fur receded as her lips plumped up and her nose became a petite human's nose. Her ears traveled from the top of her head to the side and became more human like. The only thing left was her eyes, as they were still that of a cat. Missy blinked a couple of times and soon she had emerald green eyes. She could also see colors for the first time.
Where Mary's cat once stood was a beautiful 23 year old woman. Now Mary wondered what would happen next.
