PLEASE HELP CAT CAME HOME INJURED

I have a 1 year old male who came home last night in real bad shape.his nose was bleeding his eyes were rolling back in his head he was drooling severely his mouth would not shut and he was trembling.I though he was poisoned cuz I lost another male cat two years ago with almost the same symptoms, just no bloody nose.this morning I was very relieved to find him still alive and very alert.but it seems like his nose is broken. I am almost certain he can't smell and an worried he will starve to death because it seems so far like if he can't smell it he won't eat it.he is a hungry little devil and never refuses food until this happened.I really REALLY don't want to lose him, he is the youngest and third generation of my main cat(he would be the grandson) his mom was just hit and killed by a car a week ago in front of my house,I can't lose him too. I would appreciate any and all advice or experience with this sort of thing.thank you.

It sounds like he had some sort of traumatic injury, If I were you I would get him checked out by a vet ASAP. 

I don't think there's anything you can do for a broken nose at home. He may also have internal injuries, so I second a vet visit as soon as possible. If he's not eating, you may need to syringe feed him until his nose has healed, but without knowing what, if any, other injuries he may have, I hesitate to recommend this because some cats fight it and he could injure himself more. So definitely vet visit before anything else.

I can only second what others have said.  It is essential that your cat see a vet as soon as possible.  I know it is Sunday, but emergency vets should be open, or you can see if your normal vet has an after hours number you can call.  Please don't delay/  It sounds like your kitty is very seriously hurt.
