Find a herp/exotics vet near your area. Cats have a whole spectrum of bacteria in their mouths/on their claws. Infection can start very quickly and should be one of the first things treated for the snake to have any chance of survival.
Also, if living in a house with a cat(s) and snake(s), there should be extra measures taken to keep snakes in their enclosures, or cats out of the enclosure. I haven't seen a cat yet that hasn't gone into "predator/defensive fear/aggressive curiosity mode" once a snake is spotted.
