for the prompt: pet, Haibara.
It's a perfectly normal afternoon in Agasa's house when it happens.
Conan's reading a book (one with actual kanji instead of pictures, thank heavens), when the background noise of Haibara's typing and Agasa's... whatever contraption the professor's working on gets a new addition.
One that sounds suspiciously like meowing.
By the time Conan looks up, there's a small ball of fluff working its way rather determinedly from the seat of Haibara's swivel chair (how had it even gotten up there in the first place?) up her labcoat, tiny claws hooked in the white fabric.
Haibara doesn't even twitch in the slightest when it reaches her shoulder and reveals itself to be a very contented-looking feline, purring loud enough to rival a hand-held vacuum cleaner twice its size.
"Haibara," Conan says, because he knows that she likes animals but this is frankly ridiculous, "there's a cat on your shoulder."
"Why, thank you for pointing that out, Kudo-kun, I would hardly have noticed it myself," she says, turning her chair to face him, voice even drier than usual. "Also, she's a kitten. Aren't you, Irene?"
Except that her voice goes warmer at the last part. Because apparently a cat – sorry, kitten – gets nicer treatment than him now, of course.
Not to mention... "You named it Irene? Seriously?"
Both cat and human give him unimpressed looks, appearing for all the world to be the most bizarre pirate-and-parrot duo in existence.
"Not everything is about Sherlock Holmes, Kudo-kun," Haibara says as she stands up, the cat somehow managing to keep its balance perfectly fine on her shoulder despite the movement.
"It's all right, someone's just jealous your name is better than his," he hears as she walks off towards the kitchen. "Come on, let's get you some milk."
Conan's still staring in disbelief when Agasa walks past with a box of bolts and sets it down on his work table with a clatter. "Haibara has a cat now?"
"Oh, you mean Irene-chan? Ai-kun found her in the yard a few weeks ago – she was soaking wet, the poor thing must've fallen into a drain." Agasa pauses in his search of the box to look up at Conan. "I'm surprised she came out while you were around, though, she always hides when Genta-kun and the others come over."
"Yes, because Genta is much more terrifying than Haibara in one of her moods, I bet," Conan mutters half under his breath.
"I heard that!" comes the distinctly annoyed voice from the kitchen.
