Based on the scene from Sabrina the Teenage Witch, between Salem and Aaron.

"Are you sure you can do this?"

"Yes, of course! Animals love me! I ventured into the deep of the Amazon rainforest and played with lions, jackals and panthers!"

"Well, Plagg is not a panther but he is a handful. I can't leave him on his own for more than a day, he'll wreck the place. Nino is busy, so is Alya, Marinette is with me. Plagg hates kennels and hiring a random pet sitter is out of the question."

"I told you, I can do it while you go with Spain with that Mari-loser."

"She's my designer. I can't model naked."

"I'll like it if you would..."

Adrien stepped out of Lila's clingy grasp, heading out of the door. Before he left, he turned to his pet black cat lying lazily on the white couch.

"Plagg, behave."

Then he was gone for the weekend.

Lila made a brief glance to Plagg and then walked away to the kitchen.

Plagg moved around to face the TV. With remarkable ability, he pressed the red button on the remote controller and a documentary on Nazi-occupied Italy popped up on the screen of the 60-inch TV.

Plagg opened his mouth. However, instead of a cat's meow, a lazy, deep voice came out. "Oh, good old Mussolini. He put the fashion in fascist."

"How did the TV get turn on?"

Lila entered the living room, holding a plate containing a sandwich and a glass of water in both hands. She glanced to Plagg and frowned. "Fur ball must've rolled onto the remote. Lazy feline."

She plopped on the couch, propped her feet up, and pressed a button on the reporter, the TV now presenting a cheesy Soap Opera.

Too cheesy even for him, Plagg's paw pressed the button again, switching back to his documentary.

"Hey, paws off. Kitty off the couch." Lila reached over the arm of the couch and pulled out a water spray to which she happily used it on Plagg, sending him jumping and running away with a cry.

Lila smirked with sick delight to herself. She grabbed the remote, going back to her soap opera.

"The brain the size of a marble." She said before she took a bite of her sandwich.

Plagg glared at her from the counter.

"Listen here, pretty girl, you do not wanna start a war with me. I started World War I and II. Why do you think Hitler was scared of cats?"

A day passed and Lila proved to be the worst cat sitter ever.

She slept in till 12, spent an hour of a hot shower and hadn't even fed Plagg once.

Luckily Plagg had easily get his camembert cheese out of the fridge.

The phone rang. Lila ran for it, wearing Adrien's cosy white bathrobe.

"Hello?"

"Hey, Lila. How are you doing?"

"Oh, Adrien! So good to hear from you again!"

"How's Plagg?"

"Oh, he's fine! He ate all the tuna in one day! You need to childproof your home. He keeps pawing at the cupboards."

"...can I talk to Plagg?"

"What? Did you just say you wanna talk to your housecat?"

"He's gets aggravated if he doesn't hear my voice."

Lila raised an eye at Plagg and placed the phone on the table right under the cat's chin. "He wants to talk to you."

Plagg looked at the phone. "Meow?"

Just then, the doorbell rang, and Lila left to answer it.

"Ok, Plagg, something is definitely wrong. You don't eat tuna fish or any normal cat food except cheese for mice. And I don't keep food for you in the cupboards! Say one meow for hungry but can get food, two meows for starving to death."

"Could've been worse." Plagg said. "Liar cheeks is getting pizza with the money you gave her."

"What? I gave her that money for emergency!"

"I told you she's bad news from the start, but you insisted that there's some good in her."

"There could be!"

"The only good she has in her is in her butt and even that is no good."

"Ok, Lila is not the best sitter but there's no one else! Plagg, there is a reason why you need supervision. You have no conscience, no common sense, no discipline. The last time I left you alone for two days, you trashed my place!"

"There was no more cheese left."

"Ah, God! Why can't you be more like Tikki?"

"Your girlfriend leaves Tikki with her baker parents who tend to her every need. Next time, leave me with them!"

"Marinette is not my girlfriend!"

"Adrien, come on!"

"Coming, Mari! I gotta go. Talk to you later."

"Whatever. Have fun with your girlfriend."

"For the last time, she's not my girlfriend!"

And the conservation ended.

Lila came back with a box of pizza, giggling. "That delivery boy was practically drooling over me." She swiped the phone. "Adrien?"

Hearing nothing but the dial tone, she put the phone back and glared at Plagg. "When Adrien and I move in together, we are so getting a dog."

Plagg hissed.

And when she turned her back on him, he spotted an orange sweater handing carelessly on a chair.

His eyes twinkled.

Plagg worked on destroying the garment.

He tore and ripped and bit and pulled and snatched and ruined it.

Lila screamed when she walked in on him. Her expensive cashmere sweater threaded to ribbons.

Lila wails "My favourite sweater!" She wailed, gathering the clothing in her hands. She looked up, downright furious with Plagg. "Alright, I had it with you, you mangy furball!"

From underneath the table, she whipped out a car carrier. She quickly grabbed Plagg and stuffed him inside, slamming the door shut and walked away, giggling gleefully.

"Okay...maybe I didn't think all the way through…"

Plagg wasn't one to give up.

"Almost...there…"

He was using his collar and the key to unlock the lock holding the door shut.

"Oh, man. Why didn't I learn levitation?"

Just then Lila entered, forcing him to hide his intelligence by zipping his collar back and causing the key to fly across the room.

Lila paid no attention until she got to the fridge and took out a plastic container.

"I cannot believe he's giving you the leftover cheesecake!"

A twinkle caught her eye.

She bent down, picking up the key and dangled it teasingly in front of the captured cat.

"Don't wanna lose this, do we kitty?"

She sauntered away.

The cat carrier went silent.

…

…

…

…

…

"This...means...WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAARRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR!"

Lila returned three hours later, licking the remains of the cheesecake on her thin lips.

She briefly glanced to the cat carried but stopped in her tracks when she saw Plagg's long black tail sticking out as still as a statue.

The cat wasn't moving.

"Dio mio!"

She fumbled with the key.

"No, no, no! No, no, no, no! Adrien is gonna kill me!"

After much fumbling that would make Marinette look graceful, Lila got the door open so she carefully took Plagg's still body out. She gently rolled the cat, desperate to get a reaction.

"Wake up, kitty! Come on, kitty! Kitty? Kitty?"

Nothing.

"Dio mio! What I do? What do I do?"

Plagg sniggered and quickly went back to playing dead. Lila let go of him and looked around.

"I have to…uh…bury it! I uh…bags! Freezer! Tell Adrien he ran away!"

She swung around in her panicking, seeing Plagg alive and running away.

She seethed. "Oh, I'm so gonna kill that cat!"

She raced after him but lost him in the hall. She knelt down, creeping like a cat herself. A breeze touched her face, making her whipped her head around to the front door swinging open.

"Uh oh. I'm pretty sure Adrien said don't let Plagg out."

Without a second thought, she hurried out.

And the door was shut.

And it closed on her bathrobe.

Lila tried to get the door open but couldn't.

"No problem. I'll go around the back."

She walked forward.

Her bathrobe ripped.

She ended up butt naked.

"…Dio mio."

It didn't help that Adrien lived in a high-end detached house in a secured estate completed with security.

In no time, the neighbours called security about a raving naked woman.

"Did that model bring home a hooker?"

"No, Adrien would never do that. Besides, he's gone to Spain."

"That girl is downright crazy."

"No, wait! I am not crazy! He's my boyfriend!"

"Adrien never said he said a girlfriend.

"He has stalkers.

"I am not a stalker! I'm house-sitting!"

"Adrien hadn't said anything about having a house-sitter."

Too bad Adrien was so busy with getting to work in Spain and worrying about finding Plagg a sitter, he forgot to tell security that Lila was staying!

So, she had no evidence she was supposed to be here.

"Just call him!"

The officers did but Adrien wasn't answering. Several calls were made but each time the model didn't pick up.

Lila looked less of a legitimate caretaker and more of an unlawful squatter.

"It was that stupid cat!"

"His cat? Plagg?"

"Plagg is so lazy, he wouldn't even lick himself."

"He's not lazy, he's EVIL!"

Green eyes peeked through the mail slot, watching an angry Italian woman wearing a rubbish big getting dragged away by security guards.

"It's a little early for a full moon."

Plagg crackled with wicked laughter.

"I'm home!"

Adrien entered his home, looking pleased with himself, even more so at clean his home looked.

"Good, you haven't destroyed the place again."

Plagg yawned.

"Lila? Where are you?"

Plagg looked away, almost looking guilty.

"Where is she? I have to meet Marinette at the office for lunch."

"Gonna have fun with your girlfriend?" Plagg asked.

Surprisingly, Adrien smiled as he blushed. "Well, I'm not gonna deny that."

Plagg perked up. "You and Marinette are dating? I knew it!"

"Yesterday, we finished early so Marinette and I went to my room to celebrate, we ordered room service, we drank too much apple cider and…slept together. Now we're dating."

The phone rang.

"Hang on, I'll get it."

Adrien left the living room. Plagg looked at his paw, seeing flicks of fur sticking out of place but decided not to groom himself.

A minute passed and Adrien returned, not happy with Plagg.

"Plagg, did you know that Lila was arrested for public indecency and squatting?"

"Lila in jail? The brain the size of a marble."

Adrien glared at him.

"When Mari and I move in together, we are so getting a dog."

Plagg gulped.
