My cat's intestines are hanging out his stomach, help!?

I found my cat in the corner of my bedroom sleeping, I went to pet him and noticed it smelled like feces and something was on his stomach. At first, I thought he had poo stuck to his fur, but it was too big and pale for then, then it struck me : those were his intestines. He then started growling whenever I touched him, so I'm guessing he's in some major pain. I think he got run over by a car, and if this is the case, he may as well have broken bones (ribs, pelvis, etc.). He's on his way to the vet right now, I haven't really seen him in 2 days so it's possible that he's been like this for that long. I'm wondering what are his chances of survival and if so, how much will the surgery cost?
