Chapter 1

The night had been quiet, with only the soft snores made by the crew members as they slept. They were all dreaming of adventures and reaching the goals that they wanted to achieve in life. There were no nightmares, simply wonderful stories of what each person imagined and hoped would be in their future.

The seven friends had partied all night, celebrating the finding of a large amount of treasure. They had happened to come across a pirate ship that was sinking, most likely defeated by an enemy that had more powerful. It was full of many different animals, and a lot of gold.

Since no one had been there, they were able to just take it all. Nami had been extremely excited about this, and insisted that they have a party.

No one objected to this, so they had a feast, competitions, and told each other stories. Everyone enjoyed it, looking forward to the next time they could do it.

When Robin had finally pointed out that they should probably go to bed to be well rested for their next day, they had all reluctantly agreed. But they had been really tired, and fell asleep as soon as they hit their beds, forgetting to have someone take the watch.

Sanji was the first wake up, he often was because he was dedicated to having breakfast at least started when everyone else got up. He walked to the kitchen, planning on what he would create for Nami and Robin.

His movements woke one of the other boys and the reindeer. Usopp yawned, rubbing his eyes as he almost fell out of his hammock.

"I'm so exhausted…" Chopper said as he looked at the sniper, knowing he would be the same way.

"Yeah… Last night was so fun, I think everyone will be tired today." Usopp said.

…

Nami and Robin were in the girls quarters, getting dressed, though Nami was struggling with this. She had challenged Zoro to a drinking duel, both of them betting the portion of the treasure they were going to receive, and neither of them had given in, resulting in a draw due to the fact that they ran out of sake.

She was still dizzy from that, even after sleeping.

Both of the girls soon walked to the kitchen, greeted the cook, and sat at the table. Usopp and Chopper soon entered as well, talking about what had been the best part of the party.

"I think it was when we ran out of food, Luffy looked so disappointed! It was hilarious!" Chopper squealed.

"No, I think it was when Sanji tried to dance with Nami!" Usopp laughed, "She got so angry at him for that!"

They continued their conversation as they sat down across from the girls.

Sanji turned, "Its ready! Hey where are Luffy and Zoro?"

Nami sighed, "They're probably still sleeping, too tired to get up I guess."

"Well, if they don't eat now, Luffy will just demand way more food later. Can you go get them Chopper?"

"Sure Sanji!"

Chopper hopped out of his chair and ran to the men's quarters, his hoofs clopping softly on the wood. He entered the room and looked around for his two friends, but couldn't see them in their beds.

But he did see something in them. All of their clothes were laying in a pile on the hammocks.

Chopper rushed back to the room where the others were waiting patiently, and he told them in a panicked voice, "Guys! They're missing! The only thing they left behind is their clothes!"

"What? They're gone, and they left their clothes?" Usopp said as he looked at Choppers worried face.

They all calmly went back to where Chopper had seen this, thinking that Chopper's eyes had tricked him, and he had overreacted. But when they got there, they saw that his words were true.

"Why would they leave? And without their clothes too?" Nami wondered, trying to understand.

"Look! Luffy's pile of clothes are moving!" Usopp exclaimed.

Robin walked forward slowly, reached into the hammock, and pulled some of the clothing away.

She was slightly surprised by what she saw, and seeing her expression, the others came forward as well to have a look at what it was.

There lay a extremely cute black cat. It's tail flicked back in forth as it continued sleep soundly. It's paws twitched slightly, and it's head turned a bit, moving the straw hat that say upon its small head. Though hard to see, they could make out a scar beneath its left eye.

"Oh no." Nami put a palm to her face.

"Wait, is that Luffy?!" Usopp yelled, very confused.

This made the cat wake up, opening its eyes and stretching its mouth into a large yawn, its sharp white teeth gleaming. It looked around at the group of people standing around it.

The cat tried to speak, but instead it let out a small meow.

It looked surprised when this happened and it stared at the crew members as if they knew why this happened, and wanted them share the answer with it.

"Luffy?... You are Luffy… Right?" Chopper squeaked nervously.

The cat looked at him strangely, and then nodded it's head.

"Ahh! Luffy's been turned into a cat!" He started to run around in circles.

"If this is what happened to Luffy, I wonder if…?" Robin stared towards Zoro's pile of clothes.

She went over to it, and did the same as she had before, pulling some of the clothing aside. Underneath was another cat, but this one had green fur. He was curled up, the three earnings attached to his triangular ears moving slightly as he breathed in and out.

"Zoro is a cat too." Robin told her friends as they stared in her direction.

"What…? How…? Why…?" Nami questioned slowly.

Luffy once again tried to speak, this time being able to control his vocal chords better, though you could still hear the meow in it, "We're cats? Me and Zoro?"

They returned their gaze to him, glad that he was still able to talk.

"Yes, that's how it seems to be captain." Robin responded to him.

Zoro opened his eyes a little. What was this talk about them being cats? He looked down at his hands- No wait! They were paws!

He leaped upwards in shock, his tail puffed up and fur on end. He flew through the air, only to fall back down and hit the ground with a crash.

"Oww…" He groaned with his face in the floor.

"Are you ok Zoro?" Luffy asked as he jumped out of his own hammock, trying to make his way to the green cat.

But when he tried to walk on his paws, he just tripped over himself ended up in a pile of fur beside Zoro.

"How do you use these things?!" He waved his tiny paws in the air.

"How should I know!" Zoro hissed in aggravation.

Robin giggled softly at the sight of the two cute cats as they started to tumble over top each other trying to fight, but failing miserably.

Luffy let out a yowl, breaking away from Zoro, "Ow! What was that?!"

There was a small scratch along his right side that was bleeding slightly.

"You have claws now, so you're going to have to be more careful. Zoro must have caught you with one of his."

"Ahh! Luffy you're bleeding I'll help you!" Chopper panicked, looking around for his medical bag.

"Calm down Chopper, Luffy can just lick it and it will be fine." Robin explained.

"Lick it? Why would I touch myself with my tongue?" Luffy didn't understand at all.

He looked into Robin's eyes, which seemed to just repeat what she had said to him. So he decided to try it.

He stuck out his now spiky tongue and ran it across the scratch. It felt pretty natural, so luffy repeated this, again and again, which made his fur become slightly slippery and wet. The blood had soon stopped, and it didn't sting as much.

Zoro had seen this weird thing that Luffy was doing, and decided to try it, even without any wound of his own. He was soon rhythmically licking himself, which felt nice on his soft pelt.

"This is just strange…" Sanji commented as they watched the two cats.

"If you have to watch your claws, you should probably watch your teeth as well. Those things sure can hurt…" Usopp added as he remembered times he'd been bitten by different creatures.

Luffy finally stopped his grooming and looked up at his friends.

He then demanded, "I want meat!"

Note: My name is a good enough reason for me to write this.

See what I did there with the title? Cat-ain Luffy and Swords-cat Zoro

Also, I imagine these two as being very cute cats.
