He was Red Hood. A violent anti-hero who people of Crime Alley feared, so why was he taking care of a cat?! But he couldn't convince himself to kick you out.
"Ugh... you're not making this easy, y'know," he told you as you climbed on his lap, getting your fur allll over his pants. As much as he wanted to be mad at you, he couldn't, not after how he found you, shivering in the rain.
He begrudingly pet you, "If Bruce ever found out I have a weak spot for a cat..." he mumbled to himself. The others would never stop making fun of him.
"Awww..." he let himself say when you purred, "You're so cute. I'm glad I found..." he stopped himself when he realized he was getting sentimental.
It was stupid.
You were just a cat! He could barely afford to feed both him and you, anyway, yet he found himself skipping meals once in a while because he couldn't stand seeing you as sad and starved as you were when he first found you.
This wasn't supposed to be permanent, he was supposed to send you to a shelter weeks ago. His landlord didn't even allow cats!
"You're a real pain in the аss, y'know that, kitty? Ruining my life and you don't even care," he blamed you, though deep down, he didn't believe that at all.
You were his, and that was that. Bruce Wayne's dead son turned anti-hero was a cat dad, even if he wouldn't admit it.
