Chase's POV

I sigh as I finish the machine. I made it to help with my DNA lab work. It had a clear circle on the top for the beam and a computerized control panel on the back so I could safely control the beam.

I aimed the machine's beam at the mouse I was working with and pressed a few buttons. My stomach protested the lack of food for the last couple hours and I set the machine on autopilot before leaving it to do its work and heading up to get some lunch.
'Maybe Oliver made grilled cheese for everyone again. Man, I hope so.'

Reader's POV

I sighed as I skipped into the lab, looking for Chase. I was going to tell him that his new machine parts had come in but he wasn't there. I looked around before spotting a mouse,"awwww! You're so cute!"
I walked over behind the mouse's cage and picked it up, letting it roam on my palm," now what might Chase be doing to you, hm? Is he trying to make you breathe fire or grow massive claws or become super smart like him?"

I giggled as a thought came to mind," Super Chase and Mighty Mouse! The superhero team of the century! No villain escapes their sight!" I gasped as the mouse jumped down and raced away," no! Mousy come back! Chase'll kill me if you disappear!"

I run after said mouse and a machine that I guess Chase had programmed to defend his work shot a ruby red beam out. I scream as it hit my shoulder and I passed out.

I groaned as my eyes opened,' why is everything so big?'
I shakily got to my paws and- wait, PAWS?! I looked down and let out a loud screech," WHAT THE HECK IS GOING ON?!"
A sliding door caught my attention and my ears swiveled to the noise. I turned and saw Chase come in," oh thank goodness. If anyone can help me, its him." I meow to catch his attention and he smiled as he came over," well, would you look at that. It worked! My DNA modifier worked! I changed a mouse into a kitten!"
"Wait. YOU DID THIS ON PURPOSE?! YOU WERE TRYING TO MAKE A MOUSE INTO A CAT?!" All I heard though was a bunch of meowing nonsense. Chase lifted me up and inspected me," huh. I thought I bought a male mouse. Maybe I need to check that out before next time."
I squirmed and his attention was brought back to me," oh well, I'm sure (y/n) will like you. I'll give you to her so she can watch you until it wears off."
He shifted me into a comfortable carrying position and left the lab. I blinked as the harsh sunlight hit my sensitive eyes. I mewled and buried my face in his arm. He chuckled and I felt warm and safe. He started walking to the kitchen,' hey, Bree. Have you seen (y/n) anywhere?"
"Um, maybe. I think I saw her messing with Kaz's stuff a few hours ago."
"(Y/N)!" Kaz's yell caused my ears to flatten as he burst through the door to the boys' room," where is she?! She mixed up all of Oliver's and my video games! And put Pop Rocks in my bed! Where'd the cat come from?" He looked confusedly at me. I lifted my head and mewled again. His eyes softened considerably and he held out his hands," can I?"
Chase nodded and handed me over to Kaz who sat on the couch with me and gently pet my back. I purred as he scratched behind my ears and closed my eyes in pure bliss.
"Who knew Kaz was a cat person?" I heard Bree stifle a laugh.
"What? Can't a guy like something cute without being teased?"
"Nope." Bree laughed as Oliver walked in with the groceries. He set the bags down and Bree ran around, putting them away in seconds. Oliver sat down beside Kaz and glanced over at me before starting to read a comic. I pouted and walked in between the comic and him. I sat down on his leg and mewled," pet me. I'm cute."
He sighed and rubbed my head as he kept reading.

Eventually, Chase took me back and headed up to my room. He knocked before turning the knob," huh. That's funny. She's usually in here (activity)." He chuckled," You know, its cute how determined she can get when she doesn't get it right. She sometimes spends days in here by herself practicing until she gets it right."
My eyes widened,' did he just call me cute?!' He looked down and we made eye contact. He smiled before closing the door and heading somewhere else," oh well. I guess I'll watch you until she gets back." He opened another door and I immediately noticed how clean it was. The exact opposite of my room.

He closed the door and dropped me on the bed, sitting beside me. I mewled and crawled onto his lap, bumping my head against his hand. I saw the smile on his face as he stroked my (length), (natural color) fur. I purred and relaxed under his touch. 'He's good at this...' I thought as I curled up and closed my eyes, purring until I fell asleep.

I woke up and noticed I was alone. In Chase's room. With no one watching me. Alone. Time for mischief. I hopped down and padded around before coming to his bathroom.
'Why does he even have this stuff when his tube provides all of it?' I shook me head as I messed with the tap until it turned on. I left it on and went to the toilet area. The paper caught my attention and I jumped, clawing at it as it unrolled onto the floor. I step back to admire my work and step up to the sink. I nudge it open and mess around with all the chemicals. The door shut behind me as I curled up behind cleaners and soaps. I heard the door to the hallway open and Chase walking around, probably looking for me. He yelled out,' there's him finding the water from the fish tank.'
The door to the bathroom opened and he yelled out,' overflowing bathtub'
"That cat!" 'The toilet paper'
I accidentally knocked a spray bottle over and everything was dead silent until he opened the door to the cupboard. My ears flattened and I shied away from the light. His hands wrap around my middle and lift me out," did you do this?"
I mewed
"Naughty kitten." He laughed and dropped me back onto the bed," almost as naughty as (y/n). But I guess that's one reason I love her."
I felt sleepy and curled into his side, falling asleep to the sunset's light.

-next morning-

I yawned and stretched. I smiled when I saw fingers and nails instead of paws and claws. I looked to the side when I noticed the arms around my waist. I blushed when Chase's sleeping face met my eyes. I gently tried removing his arms but he groaned and held me tighter.

Next, I tried waking him up," Chase, Chase, wake up. I need to go."
He grumble before he opened his eyes and jumped away," WHAT THE HECK?! (Y/N), what are you doing in my bed?! And where's my cat?"
I smirked," why, she's right here, Chase."
I laughed at his shocked expression," you mean to tell me that YOU are my CAT?!"
"That's one way to put it." I giggled.
"How?!"
"A machine in the lab shot a beam and it hit my shoulder instead of the mouse. Then I fainted and woke up as a cat."
"Oh. Well, at least you were my kitten for a day." He leaned over and took my hands.
I blushed as he leaned closer," y-your kitten?"
"Mine~" he pressed his lips to mine and pulled away a little bit later, smirking at my red face. He stood up and tossed me a shirt of his, winking.
I blinked.

"CHASE DAVENPORT!"
