Summary
Up rises Kacchan’s slinky form, thick loaf slimming into his lean body as he walks with easy steps up into Deku’s space. Innocently, he pushes forward to let their noses touch, their whiskers mingle, and although it tickles Deku to no end, he absolutely does not pull back.
Not when Kacchan is this close.

Summary
Shinsou once told Izuku that he wanted to become a cat. His existence would be carefree, all his needs would be met. He would be fed, he could sleep half the day with impunity, and he would get free scratches. He wouldn't have wished for a more relaxing life.
Izuku, who now had first-hand experience, couldn't agree with him in the slightest.
He didn't feel relaxed at all.Or: Midoriya Izuku disappears unexpectedly, Eri finds a green and very friendly cat, and Aizawa... Aizawa changes his mind. His students are angels, actually. This creature... is a menace.

Summary
“Calm down,” Aizawa murmured, his voice low and soothing. “You’re safe here.”
'Safe?!' Izuku thought wildly, his ears flattening again as he stared up at the two pro heroes, who were now watching him with curiosity and concern. 'How am I supposed to be calm when I’m literally in the house of two pro heroes?!'
--
Izuku has a quirk that allows him to turn into a cat, but as of now...He's kind of stuck like this, like a cat, for /months/. It's fine, though, it means that now he can't be chased by Eraser-Head! After months of running away from that man, he would never suspect he was a cat! He thought he cheated the system, except that being a cat—a kitten—is harder than being a human. And so he got pretty roughed up when a rock was thrown at him, and many other things piled up the same way snow or trash piles up on the street.
After an altercation with a dog that left him on the brink of death, a cat dragged him to the house of a human
Out of all the faces on this planet, why Aizawa's? -

Summary
Quirk discrimination does not only apply to those who don't have one at all. In a world where a simple cat quirk cause Midoriya Izuku to be seen as weak and cutesy, he decides to prove to as many people as possible that he can be better than them all. Will he end up a hero who runs on spite and anger, a villain who thrives on it, or something right in the middle?
I orphaned this fic because I was embarrassed about how bad I believed my writing was. reading it back now, I think its salvageable and with time will reupload all thats written so far, write new chapters, and edit old ones! sorry to all my old readers, but I hope my writing is still liked!!

Summary
Hizashi has always been an upbeat cat; vocal, loud, energetic, and always eager to wake up his owner early in the morning for breakfast. Despite his past experiences with a bad owner, he trusts his new one, Nemuri, with his safety and his life. She gives him love, care, food, and water, so why would he need anything else? His life is perfect. But then… Nemuri comes back home with a new cat, and Hizashi has no clue what to do.
Shouta has been a street cat his whole life, constantly avoiding humans because that’s what his mother told him to do before she was taken away. She always told him that humans were monsters, drilling this fact into his brain so many times that any time he caught a glimpse of one in his alleyway, he’d find shelter in another one. He has to be logical and rational to survive, or else he’ll get killed. But once he finds himself injured and freezing to death after a storm, he has no fight in him when human hands pick him off the ground and bring him somewhere new.
~Or~
Hizashi and Shouta are cats, and Shouta has to adjust to living the life of a housecat while Hizashi has to befriend the most antisocial and aggressive feline he’s ever met.

Summary
Izuku’s quirk is called catform.
They have three forms.
The first is their base form, it’s the most humanoid. They are perfectly normal except for cat ears, a cat tail, paw pads on their fingers and toes, and enhanced reflexes.
Their second form is hybrid. It is more cat like. Their eyes change shape and they grow whiskers. Their hand morphs into paws with claws as sharp as knives. Their legs grow more powerful and coordinated, their tail grows longer and whiplike. They can use it as a weapon in a pinch. And their reflexes are heightened even further.
They can just morph their hands into paws if he wants to.
Their third form is just cat form. They can transform into any house cat. Clothing and objects they carry morph with him.
Also they meow at random when they talk. I had a lot of fun with that.
