Mary felt something bump against her body. She snapped awake, hissing and ready to fight whatever had disturbed her. Once she was at attention, she found it was simply a large ball of yarn.
"I got your toy," Jess said.
Mary testily batted the yarn with a hand/paw. She pulled at the loose string, wanting to dig her claws into the material. Soon she was batting it across the room and scampering after it, pouncing on it and rolling around clutching it in her claws and teeth.
"Got you a few more things, too," Jess said, putting a plush mouse doll on a chair and holding out a small red knit ball. Mary's nose suddenly perked up. She looked at the ball in Jess' hand.
"That. What is that? That ball." She seemed almost in a crazed trance as she carefully walked up to Jess, standing back on two legs. "Give it to me."
"You want this?" Jess raised it higher. Mary instinctively leapt up and swung a paw at it, missing by a couple feet. Jess was almost two feet taller than her cat form, and easily held it out of reach.
"Give!" Mary demanded, continuing to jump. Its scent was invading her mind. She didn't think she had felt so intense about anything before now. She absolutely had to have that ball so she could lose herself in its intoxicating air forever.
Just as Mary was beginning to seriously consider clawing her best friend to pieces in order to get the ball, Jess tossed it across the room. Mary darted like lightning to where it fell, bowling over it and slamming against the wall. She frantically nibbled at it with her small fangs, ecstatic.
"I had a feeling you'd go for some catnip," Jess laughed. She walked up to the cat-woman, bending down to pet her on the head. Mary purred loudly as she continued clawing at the ball. She spat out some of its fabric, but continued nibbling away.
All of a sudden, she felt a tightening around her neck and something wet in her mouth. The ball of catnip became squishy in her jaw and its odor lessened. Mary dropped it, wondering what was going on. She brought her hands to her neck and felt something there...a collar?
"J--Jess?" she asked, looking up at her tall friend...who was apparently getting taller!
"You're so cute, I decided to keep you as a pet!" Jess said down to the regressing creature, now more a cat-girl than a cat-woman. "I just spilled the age regression vial and the cat vial onto that ball of catnip." She giggled as she watched her friend shrink in size. Her blond hair completely shrank into her head, leaving her with perfect orange and white feline fur. Her whiskers grew out several inches and her fingers became a little shorter, though still partly human. Her fangs lengthened as her body became younger. Her shirt was draped like a robe over her entire body, hanging down to her ankles. Mary was only two and a half feet tall now. Her body had changed to the equivalent of a sixteen-year-old. She still had her six breasts, though slightly smaller in proportion to her body. She whimpered, attempting to pull her large collar up so her upper row of breasts weren't exposed. She fingered her red collar with a gold tag hanging from it.
"Mrrwhy did youw do this?" Mary asked, a definite cat timbre making its way into her voice.
"Oh it'll be fun! You get to do all the things pets do! Just relax around the house and forget about work and stress and paying bills! I'll even let you outside, if you promise not to be seen by anyone."
Jess did have a point. Before today, Mary didn't have many opportunities to relax and cut loose. Would being a pet cat for a little while really be that bad?
