Twilight Sparkle is in her lab, working digilently on her a new potion for Pinkie, with cat infusions. It has DNA from Opal, Rarity's cat. She is working really hard and she's stirring the potion too hard and some of it splashes on her body. She gives a little gasp of surprise.
"Oh, noo.... nya.... nyaaaoww!?"
All of sudden, her voice morphs to a higher register and her hooves turns into paws! Her body is partially becoming like a cat! She feels... weird and frisky. She bats at the potion, knocking it off the table and the puddle spreads all over the floor. One of her many machines starts sparking at the puddle spreads. The real Twilight Sparkle is panicking about the electricity, but there's nothing she can do, she's becoming a cat now.
"Meow!? Meow! Meow meow meow!"
She's hissing at the puddle, and her mouth is full of fangs now. Her eyes are slitted pupils and her cute little pony tail becomes a swishy cat tail. At the end of her new paws are claws. She extends them experimentally, pushing the claws in and out. The last thought of her pony mind was this: Heck, I've got to find Rarity to and see if she can help! Her house is closest!
The machine is broken, by the way. Just if you were wondering. Her cat instincts take over and she just starts playing with bottles! Smash, crash! She swishes her new kitty tail in delight, back and forth, her pupils dilated. Then that memory, that thought takes and she remembers... right, Rarity! I have to find Rarity! The associations are something like Rarity has a cat, she handles cats, and she can help me.
Twilikitty runs out of her lab and bumps into Spike. Spike looks down in surprise at his new master, who is now a cat.
"Oh no, Twilight! What happened!?"
She howls because she's a cat, she can't speak words anymore. "YOWL! YOWL! AWaaaoooOOooo!"
Spike reaches out his hand toward her, but she's already running away down the street, her now-long fur puffed out. Her paws hit the rocks of the path and the town of Ponyville is like a blur. She puts her new cat nose down and sniffs, whiskers twitching. Twitch a twitch! Twitch a twitch!
Her sense of smell is stronger now! Yes! She can smell Rarity, she can even smell Opal. She paws at the ground excitedly, tail whipping back and forth, and starts... well, it would be a gallop if she was a horse. Because she's a cat, it's a brisk run. She knows the way, she remembers it.
She's faster now! Oh, and she can fly! She forgot about that, she was so excited.
Twilikitty flies to Rarity's house and scratches and howls at her front door. It's closed! And she's gotten smaller and she can't open it with her little paws. Then she spots the cat door! She whisks through it in a flash! Yes!
THERE IS YARN IN HERE! Stop the presses, she can find Rarity later, there is yarn!
Five minutes go by as Twilikitty plays with the yarn and makes a huge mess. She's knocking over fabric, and hey! This bolt of fabric rolls! She's got her paws wrapped around it, nomming it, her eyes closed in bliss, and her tail lashing and her ears are little flat airplane ears. She's got it hugged in her paws, purring.
Twilikitty is almost half the size she was before, almost a kitten now that the transformation is ended. There's a surprised squeak as Sweetie Belle comes downstairs and finds her.
"Oh, Twilight, is that you? What happened to you? Was it Pinkie Pie?"
"Mya! Myaaa, mya, mya!"
Twilight tries to explain, but it's not working. Somehow, miraculously, Sweetie Belle seems to understand!
"You want my big sister! I'll go get her!"
A few minutes later, Rarity had a cat dish on the floor with delicious wet cat food in it! Opal was nearby, glaring at her. Twilikitty glared back. This was her territory now! Her food! She better not steal it! She crammed it all into her mouth, gulping it down greedily so the other cat couldn't eat it.
Rarity shook her head back and forth.
"Well, I hope Pinkie knows what to do. You're lucky, dear, I am well-stocked on cat food. You know you are the one who makes Pinkie's potions so we are in a real pickle of a predicament now!"
Rarity bends down to pet Twilikitty with her hoof. She hisses, she's eating! Don't touch me right now! Her fur puffs out into a little ball and her tail straightens out like an exclamation mark! Twilikitty hugs the food dish with her paws. This is mine! Mine!
Rarity backs off, hooves held up. She shares a weird look with Sweetie Belle. Twilight doesn't care, she just wants to eat this damn food. Why can't people leave her alone for like three minutes so she can eat? She's a cat. She just wants to play, eat, and sleep.
Soon, the food dish is empty. Twilikitty puts a paw on her bloated belly, feeling feel full. And tired!
She wants to take a nap. She jumps up onto the top of the refridgerator. It's really warm up here. Twilight instantly falls asleep as a little ball of purry fur on top of Rarity's fridge. Sweetie Belle puts a hoof to her lips, gesturing for Rarity to be quiet and they tiptoe out of the room.
"Let's let her sleep!"
Suddenly, Cryptic rips through the fourth wall, and yells "I HATE PONY LIFE! I HATE PONY LIFE! I HATE PONY LIFE! I HATE PONY LIFE! I HATE PONY LIFE! I HATE PONY LIFE! I HATE PONY LIFE! I HATE PONY LIFE! I HATE PONY LIFE! I HATE PONY LIFE! I HATE PONY LIFE! I HATE PONY LIFE! I HATE PONY LIFE! I HATE PONY LIFE!"
Credits roll.
Nowhere in the credits is the author's name to be found because no one cares. They only clicked on this because it had a cat. The author sighs and goes to get some coffee to write more. Imagine trying to make a hype-wave or fandom trend now that the fandom has died.
She thinks, damn, it's four hundred more days until the Generation 5 movie. That's a lot of time to write more about Twilikitty. Do you think people will like it? Hmm.
She puts the mug under the keurig and it fills with water. Instant coffee, creamer, two scoops of sugar. That'll do, writer. That'll do.
