So this was a request from PotterFanRosalinda , who is actually also writing an adaptation of this idea. Go check them out guys! I think the ending is just a little different than you said but I still hope you like this chapter!

"Mr. Stark! What in Obi Wan's name is that!?, Peter screeched as he stared, horrified, at black creature that was now meowing contently in Tony's arms.
"Peter, kid, I want you to meet Delilah", Tony looked at the feline adoringly as he stroked her back.
"W..What? You adopted a cat!?", Peter spat out the word cat, like it was a curse word or something.
"Yes, of course, what's wrong with that?", Tony almost actually looked hurt that Peter said that.
"Oh, I don't know, maybe because cats eat spiders!", Peter spat out.
"So?", Tony honestly looked confused, or just was really good at acting.
"Have you forgotten that I am Spiderman!? That...that creature", Peter pointed an accusing finger to Delilah with a betrayed look on his face, "eats my sort!"
"C'mon kid, don't be so dramatic, Delilah wouldn't hurt a fly", Tony smiled sunnily at Peter, and then turned to Delilah, "would you? No you wouldn't", Tony crooned at her as he tickled Delilah's chin, Delilah just purred back at him, but as soon as Tony looked any other way, Peter could swear she smirked at him, Peter glared back.
"Stupid Delilah", Peter muttered under his breath, glaring at the cat, who glared back, well, as far that cats could glare.
"Are you hungry baby?", Tony asked Delilah, and Peter had barely enough time to express his horror about the nickname before Tony was carrying Delilah out of the room like she was some cat royalty or something, which was ridiculous, since Peter was sure that creatures as vile as cats (who ate spiders!?) wouldn't have royalty.
"FRIDAY? Where is Tony taking the cat?", Peter was curious, since he was pretty sure yesterday there hadn't been a single piece of cat care stuff in the penthouse.
"To Delilah's room of course Peter", even FRIDAY sounded besotted by the cat, saying Delilah's name like some prayer.
"Ugh, stupid cat"
°————-°
To Peter's horror, Delilah was definitely staying, Tony loved her, even though she was as arrogant as one could be, she strutted around the penthouse as if she owned the place and sometimes when she was getting pet by Tony she would smirk some weird cat smirk at Peter.
"Delilah, honey, time for your walk", Tony insisted on walking Delilah personally every day at least once, and even though Peter moaned frequently to him that cats didn't need walks and that it was weird Tony kept saying that it was good for Delilah and he wanted her to be healthy and strong.
"Ughhhh", Peter groaned out loud but didn't have enough energy to actively whine about the walks, so Tony just gave him a warning look in passing, Delilah strutting behind him, her perfect tail swishing after her.
And the cat didn't even have any use, at first Peter thought Tony was building a robot cat or something and needed Delilah as model, or maybe Tony suddenly wanted to compete in those best cat competitions, but he didn't build some new robot or came home with any prices (because Peter grudgingly admitted that Delilah indeed was a well groomed cat and listened well, so she would totally win those), so there was only one conclusion left: that Tony actually liked to spend time with that stupid fur ball.
