"Pets?"
Harley thought about it. Hermione really hadn't had any pets up until now.
So she suggested, "There's a Magical Menagerie nearby. Why don't we take a look?
A while ago, I found a dog with a Fantastic Beasts bloodline. He's at that shop now, getting checked out."
Hermione happily agreed, and the two of them crossed the street toward the Magical Menagerie.
When they arrived, they found the shop empty.
The Witch from that morning wasn't behind the counter. All she'd left was a note saying, "The owner is out on business. Back soon."
Sirius was curled up in a temporary dog bed in the corner, with Crookshanks sprawled across his back.

The moment Harley and Hermione walked in, the cat and dog both woke with a start, their keen animal instincts alerting them. They lifted their heads together and looked toward the entrance.
When he saw Harley with an unfamiliar young Witch, Sirius got so excited that he sprang to his feet.
Crookshanks, caught completely off guard on his back, smacked his head against the cage beside him, then tumbled to the floor.
The little white rabbit inside the cage was so frightened that it passed out without making a sound.

It didn't hurt, but it was humiliating! He would have his revenge!
He let out an angry yowl, baring his gleaming teeth. "Meow! Meow! Meowww!"
"Ruff?" Sirius let out a low, confused bark, then realized what he'd just done.
"Woof, woof, woof!" Sirius barked softly, and at last managed to calm Crookshanks down.
Then Sirius scampered over to Harley's legs like a real dog, sat obediently, and stuck out his tongue.
"Good boy, Black." Harley
