Hit by car

My cat was hit by a truck 4 hours later he returned. With a bump on his head a little bit of blood on nose,and blood all over his mouth.He got lost that same day (December 22).He returned on christmas eve with no more bump but jaw was broken and he cant close his mouth or eat. Puss is in his mouth and it smells ugly like dead animal.He drank water that day but cant eat.His mouth is like broken and wont close it .I see it and its like his chin got unattached from skin.What can i feed him??? I cant take him to vet because im a daughter of an illegal alien we are poor and cant afford it.He has no nails and is neutered.He weighed 12 pounds at the time of accident.

this kitty needs to be seen by a Vet and as soon as possible...do the humane thing for goodness sake, even aliens take care of their animals...

I'm sorry I see this is a stray not your own pet...please take it to a Vet Clinic or humane society I'm afraid the poor little thing will need to be put down, please don't let it suffer like this...take it where it will be attended too...
