<human>: Can you summarize the given text in a few sentences?

While walking to class today I found a stray that I'm pretty sure was just hit by a car and has a broken rear left leg. I didn't see any blood and it's not like dangling or anything, nor is the bone protruding, but I could tell by the way he was trying to put pressure on it that it's broken. I tried calling our local animal control but "all the lines were busy" and their mailbox was full, so I couldn't leave a message. I'd really like to try to get it somewhere that won't just put it down though, since it's a younger cat and I don't think it's a terrible, messy, nonfixable break. The thing is, I don't think the shelters around here (Pittsburgh area) would do surgery on a stray and I really don't have the money to take it to an emergency vet. I'm not against paying something small for it, but as a broke college student, I don't think I can afford surgery. Any ideas of what I can do or any places I could take it would be great! Thanks!
