My old cat was bitten by a snake I believe.we didn't see her for a couple days until my mom did.For almost a week the poor cat couldn't move her back legs and she drug her self around.a day or two later she was sitting in our yard and she smelled like death and had ooze coming from her mouth.It hurt her to touch her.The place where she was bitten got worse and worse.Flies were every where on her wound and around her body.she smelled worse and she layed in the one place for a day.I don't know if the would happen to your cat,but my parents think that the snake that bit her was like as long as maybe 6 inches.after my dad killed the snake,he thinks she may have eaten too.
