Severus stays near the twins away from Black as they walk through diagon ally. The twins smile and takes his hands ignoring him trying to pull away. He eventually stops and stays close to them not wanying to be near the black dog.

Srius moves around and runs between him and the twins making severys jump and draw his wand. The twins quickly grab it not wanting him to get into a fight. "No sev."

"Are you afriad of dogs?" Fred asks.

"No! Why would i be afraid if a dog? Dont be stupid."

Fred looks at Goerge who shrugs.

Severus takes them to the robe shop.

"We dont need new robes." They say.

"Yes you do." Severus says and makes them stand on the stools.

They get sized and buy the robes themselves even though Severus wanted to buy it for them.

When they finish with that and rejoin the group the twins sneak off to the pet store even though they know Severus dosnt want to be left with Sirius.

then a few minutes later them twins go back to the group with a small box with holes in it and give it to Severus.

Severus opens the box confused and sees a black kitten with one yellow-green eye and one blue eye. "Shed so pretty." Severus says picking the kitten up.

Fred and George smile. "Were glad you like her."

"Ill name her étrange."

(An - french for strange according to google translate)

"Interesting." Fred says.

"We like it." George adds

Severus smiles and cuddles the kitten to his chest. 

The twins kiss his cheek and they continue to shop.

When they get back to Grimuals place Severus quickly takes the kitten upstairs as though he wants to hide ètrange.

The twins follow and pack there trunks watchung severus play with the kitten.

Severus looks at them and holds the kitten close. And she meows purring and starts to lick at his neck.

"We are not going to hurt her Sev."

Severis bites his lip glancing at the small kitten.

"Why would we get you something, a animal no less just to hurt her?"

He shrugs and pets the kitten as it licks his chin.

"Must think your its mummy." George says and sits at severus feet.

Severus grins and cuddles it more curling up.

She meows and curls to his chest.

Fred and George slolwy cuddle to severus so that way they wont scare him and smile when he lets them.

Severus relaxs slightly and lets the kitten walk around on the bed and smell the twins. The twins reach out to pet her but Severus stops them. The twins cuddle him confused. "We are not going to hurt her."

"I know." He mumbles.

The twins kiss his cheek as ètrange cuddles back to Severus and licks his neck. Severus smiles and lets her. The twins watch smiling thinking that its adorable. 

A little bit later Molly walks in. "Boys its time for dinner."

Severus holds the kitten more to him glaring at Molly. She just walks out and the twins watch as he goes downstairs still holding the kitten. "Do you think his pet he had for school was hurt by some one?" George asks

"Maybe Sirius and James?" Fred says

George shrugs and they go to follow Severus. They sit on either side of him and sees that the kitten is curled up on his lap. 

"So your going to carry that kitten around to now?" Remus says rolling his eyes. 

Severus just glares at him as he pets the kitten. 

"He can do as he wants with the kitten its his." Fred says defensively. 

Remus rolls his eyes, and Sirius says. "He carried the one he had for Hogwarts around to tell it mysteriously disappeared. Bet he used it for potions."

"I did not!" Severus snaps. 

"Oh then what happened to it?" Sirius says. 

Severus rolls his eyes. "I hope you get demon pox."

"What is demon pox?" Harry says. 

"Demon pox on all your houses." Hermione mumbles.

Fred looks at George. "Muggle thing?"

"Probably."

Hermione looks at them in fake surprise. "You two never heard the demon pox song?"

"Demon pox song?" Ron says confused.

"Yeah everyone knows the demon pox song." Severus says rolling his eyes.

"Demon pox isn't even real." Sirius says.

"Yes it is." Severus and Hermione said. 

"All of you eat. No more talk about demon pox or about Severus' pets." Molly says in her mother tone.

Severus smiles as Hermione laughs quietly to herself as they eat.
