Recently abandoned kitties need a home

Hey everyone, I work by Morgan State University and happened upon this pair of kitties (they're not baby kittens but fairly young) that were recently abandoned by some douchebag chick who abruptly moved out. I've been trying to look for a good home for them, they're really nice and they really want a home, especially before the cold majorly hits.

It's a brother-sister pair. The boy is orange-ish, super cute and super affectionate. The sister is grey with slight orange patches and is shy but warms up to people. Both are orginally housecats. Right now, they still live outdoors near where they used to live and that's where I've been feeding them and giving them water. I can't take em in because I already have a cat. The shelters are full and I don't want to separate them. They're very healthy and love each other very much. I really wanna see these kitties have a home so I'll help out for healthcare should anything come up, even pay in full.

I'll post up pictures later, they're very adorable!
