 The rattlesnake was poison ya non poisonous

Rattlesnakes are a group of venomous snakes of the genera Crotalus and Sistrurus of the subfamily Crotalinae (the pit vipers). The scientific name Crotalus is derived from the Greek κρόταλον, meaning "castanet".The name Sistrurus is the Latinized form of the Greek word for "tail rattler" (Σείστρουρος, seistrouros) and shares its root with the ancient Egyptian musical instrument the sistrum, a type of rattle. The 36 known species of rattlesnakes have between 65 and 70 subspecies, all native to the Americas, ranging from southern Alberta, Saskatchewan, and southern British Columbia in Canada to central Argentina.

Early spring in Mexico's Sonoran Desert when nature gives diamondback rattlesnakes their wake-up call they've spent the entire winter underground in a cozy layer away from cold and predators now it's time to head outdoors and feel the warmth of the Sun the females are free to bask to their heart's content besides warming their bodies the Sun helps their eggs develop as they get ready to breed speaking of breeding the mature males now have to fight it out to see who gets prime access to the females the male Rattlers perform a weird ritual one-upmanship they stretch themselves to see which one is the biggest tallest and strongest 

this is a fairly civilized ceremony considering time and back venom inflicts everything from extensive tissue damage swelling and bleeding to death the rival doesn't measure up so he has to leave the serpent king to his females the females are rested and ready they're resting together with the male checks him out to see if they're ready to breathe this head rubbing courtship display looks like he not only wants to be Mr.right but Mr. right now male and female can stay locked

 in Congress, for an entire day or more overall, that time neither gets rattled and after all this productive pleasuring it's time for a meal oh yeah why they haven't eaten for five months yeah no wonder they're hungry a squirrel is spotted and the snakes hemotoxic venom instantly poisons the squirrel blood the Diamondback is careful to align itself so it can swallow the headfirst bat wait the limbs fold neatly and the fur rugs the snake's innards the right way the Diamondback unhinges its jaws this way it can swallow animals that are many times bigger than its own skull one final yawn and the rattler resets its jaw
