Killer x Cat Reader

"Nightmare can we please have one day that we aren't planning how to get rid of the Star Sanses. We haven't had time to ourselves in months," Killer groaned while he, Nightmare, Horror and Dust we're sitting in the far off corner of a park.

"Your job is to destroy them, if you don't have the ability to do that then just leave," Nightmare growled back. "Whatever, you three have fun I'm going for a walk," Killer said barely catching the others attention.

He sighed annoyed and walked away from the group, following the walkway winding throughout the park.

"I do just as much work as the other two and what do I get. He treats me like I'm some sort of problem," he muttered to himself angrily.

He continued venting to himself, hoping no one heard his ranting, while following the path.

While he was walking he couldn't help but notice the persistent, panicked, meowing. He never could really spot the cat though so he tried his best to block it out.

Although he was torn between looking for the cat or leaving it be, it was probably feral anyway. But he did have a soft spot for cats, though he'd never outright admit it.

So despite how much he knew he should've kept walking he instead began searching around for the cat. He had no luck for minutes and about gave up until he saw the cat bolt out from behind a bush.

He was right it was definitely a stray no question but he could tell it was in distress. "Hey buddy, what's got you all worked up," he said kneeling down to not be as to not scare the cat.

The cat continued meowing, obviously trying to tell him something. He was at the moment looking the cat over to make sure it wasn't injured and noticed that it had recently had kittens.

"Is something wrong with your kittens, is that why you're freaking out," he said standing back up.

She then ran back into the bush with him following behind her. She ran to a small well that had the sound of kittens mews echoing from it.

Killer ran over and saw the two kittens, now immediately knowing why she was trying to get his attention.

He quickly used his magic to lift the kittens out and set them down at their mothers paws. The mother after rubbing her head against them, saying she was happy to have them back, walked over to Killer.

She started rubbing against his ankles as a form of a thank you. "Heh, you're welcome mama. I bet it's hard raising kids out here huh," he said reaching out to pet her.

She backed away a slight bit then slowly leaned into his hand allowing him to gain her trust. "Maybe it'd be best for all of you to come with me,"  he said as the kittens wobbled over to try to get his attention as well.

"That sound good to you," he asked the mom, and to his surprise she happily meowed back. "I'll take that as a yes, c'mon," he said as he picked up the kittens with her following behind him.

He walked back out to the sidewalk only to almost run into Dust. "There you are, we've been looking for y-. Really Killer," Dust said while facepalming at seeing the cats.

"You know Nightmare isn't gonna let you have a cat, let alone three," he said. "Well what he doesn't know won't kill him," Killer replied.

"Besides they don't need to stay out here, I mean I just had to fish them out of a well," he added. "You know what, do what you want, if Nightmare finds out it's your problem," Dust said before teleporting away.

"He's right, if Nightmare finds y'all it won't be good. Guess you'll just have to try to keep them in my room," he said looking down at the mother cat.

"Now c'mon let's get you situated," he said while picking her up and teleporting to his room in Nightmare's castle.

He set the three down on his bed, the kittens immediately began rolling around in the sheets completely unphased by their new location.

"Now I guess you three need names huh," he said petting the mother's (h/c) coat.

"I'll call you Y/n, you'll be Pistol," he said referring to the larger of the two kittens then the other," and you'll be Bullet."

"How do those sound Y/n," he asked getting another pleased mew from her. "Now we just have to make sure you stay away from Nightmare."

"And I need to get some supplies too. You three stay put I'll be back in a bit," he said before teleporting to one of the pet stores in the town near the park.

He grabbed a (f/c) bed for the three of them, a litter box, a ton of kitty litter and dozens of toys to keep the kittens occupied.

He teleported back to his room to see Y/n curled up with her kittens asleep. He couldn't help but smile at that, they were a cute little family.

Months passed and he still managed to keep them hidden from Nightmare, even if Dust and Horror both now knew.

Instead of trying to be annoying and threatening to tell Nightmare, they instead asked if they could have one kitten each, Dust chose Pistol and left Horror to keep Bullet.

Killer was happy that he didn't have to be in charge of them anymore and that the two really seemed to love their new owners.

He was worried that now it would be harder to keep them hidden with the three of them scattered around the castle.

Especially since Y/n seemed to be trying to sneak out of room all the time.

Though he was good about making sure she couldn't get out when he wasn't there, or at least he thought he was.

He went to get more food for her only to come back and see that his bedroom door was wide open. "Oh God," he said to himself as he began running around the castle looking for her.

He looked everywhere, except Nightmare's throne room, she had to be in there.

He tried to sneak in but stopped short when he saw Nightmare sitting at his throne. But that's not what shocked him.

Nightmare was sitting there with Y/n on his left arm rest and petting her. Though he immediately noticed Killer's presence.

"So nice to finally meet her Killer," he said still petting her. "You knew she was here," Killer asked shocked, and relieved.

"I'm no idiot. Though you did a pretty good job of hiding her and her kittens," he answered.

Killer walked over and scooped her up in his arms, to which she immediately began purring.

Without another word he left and went back to his room and laid down relieved that she was safe and he didn't have to worry about the fear of having to give her up anymore.

She quietly climbed on top of him and laid down on his chest. "You know you really had me worried Y/n,", he said reaching up and stroking her back from her neck to the tip of her tail.

She purred loudly and began drifting to sleep.

"Heh, you're right Y/n, some sleep sounds good," he said beginning to fall asleep himself.

"How about a little cat nap."
