Animal Testing

Vanessa was just putting the crushed powder from one of the pills under her microscope when a loud meow startled her, making her spill the powder all over her desk. "Princess! Can't you see I'm busy?"

Her 20-year-old, mangy white rug of a cat glared back at her. She pawed at Vanessa's feet.

"You're hungry, are you? Well too bad, I'm not... feeding... you..." She paused, an idea sparking. "Actually, Princess, come here."

She quickly hefted up the scrawny thing and held her tight as she grabbed one of the pills and shoved it down her gullet, massaging Princess' throat so she would swallow. When Vanessa knew she had, she quickly put the cat down and shut the door, trapping her and her experiment together in her room.

At first Princess showed no signs of changing, she simply glared and scampered away to a corner, far from Vanessa. Then, there was a groan. Her stomach rumbled and her fur puffed out. Her pupils dilated as her body trembled. And then the growth began.

First, the cat began to grow larger and larger, her fur receding as she did. Then, her arms and legs began to grow out, shedding their animalistic paw pads but keeping the retractable claws, just peeking from her fingertips. Her body stretched as her torso stood upright upon her now-human legs, trading her whiskers for a more recognisable face. Her fangs and slitted pupils stayed the same, however, as did the cat ears on her head, even as her white fur became a long silky waterfall of hair running down her naked back. Lastly, eight teats began to grow out on her chest, each of the four pairs becoming huge double ds that made even Vanessa jealous to their incredible, gravity-defying perkiness. Princess shivered as her soft tail curled around to rest within her cleavage.
