The hedgehog (Erinaceidae), the mongoose (Herpestidae), the honey badger (Mellivora capensis) and the opossum are known to be immune to a dose of snake venom.
The Virginia opossum (pictured in Monterey Bay, California) has a natural immunity to snake venom.
The body's immune responses to snake venom may contribute to the severity of these symptoms but have not been well characterized in humans. Treatment with antivenom is potentially lifesaving, but also carries risk, as severe allergic reactions (anaphylaxis) are common.
“It is important to note that this resistance is not absolute – we are not immune to cobra venom, just much less likely to die than other primates.” Resistance to cobra venom has a cost – receptors that are resistant to cobra venom don't work quite as well.
In the mammalian realm, hedgehogs, skunks, ground squirrels, and pigs have shown resistance to venom. Some scientists even believe the lowly opossum, which wields a venom-neutralizing peptide in its blood, may hold the key to developing a universal antivenom.

Their resistance is to the a-neurotoxin in snake venom, specifically. Domestic pigs have a genetic mutation in their cell receptors that prevents binding of the a-neurotoxin, rendering the venom useless. The resistance doesn't occur in most pigs until they are adults, so small pigs are still vulnerable.
The researchers found adaptations in Komodo dragon genes involved in coagulation that make these lizards immune from the venom anti-coagulant, protecting them from bleeding to death when attacked by another of their own species.
Sheep have a natural immunity to pit viper venom! The anti-venom you would take if you got bit by a rattler was made inside of a sheep! Luna was perfectly fine from the bite after three days!
Dogs do NOT build an immunity to snake venom NOR does having had antivenin treatment give your dog any protection against future envenomations.
Snakes will usually avoid people and bite only if they feel threatened. Most snakes are fairly harmless (not poisonous/not venomous). Even so, if you're bitten by any kind of snake, you should take it seriously.
While humans have no such natural protection, it is possible for us to build up a tolerance to snake venom.
Dry bites: These occur when a snake doesn't release any venom with its bite. As you'd expect, these are mostly seen with non-venomous snakes. Venomous bites: These are much more dangerous. They occur when a snake transmits venom during a bite.
No, cats have no immunity to venomous bites. It's an old wive's tale. Over the years, we've had mountain lions, bobcats, wolves, coyote, dogs and horses bitten by rattlesnakes and they all get sick. Antivenom is given, if it's caught early enough, within 2 hours of the bite.
The effect of venom is based on the target's weight. Cows are rarely injected with just enough venom to cause their death. Animals like this one are too large compared with snakes and their venom glands' capacity.
But, aside from young foal, adult horses do not typically die from the toxic venom from a snake bite. Your horse's Veterinarian will be more concerned with asphyxiation due to swelling, infection and secondary disease that can result from a bite.
Horses and cattle, though very sensitive, seldom die as a result of snakebites. A lethal dose of venom is based on body weight and fortunately most horses and cows are simply too large for snakes to kill. A large animal will generally survive the bite unless infection develops or the bite is on the muzzle.
Unfortunately, in the end, the python's power was no match for the cobra's venom. “It would kill the python pretty quickly,” Sheehy says.
Snake Bite. Snakebite from any snake can be life threatening to a goat. Do not worry about the kind of snake that did the biting. Treat every snakebite as if it came from the most poisonous of snakes.
A black mamba would win a fight against an inland taipan because it's larger and far more aggressive than the other snake. Still, when we talk about the “winner” of a fight between two of the deadliest animals alive, we can't truly say one will survive and the other won't.
Adults are top predators but juvenile dragons are preyed upon by adult dragons, feral dogs, wild boars, civet cats and snakes. Komodo dragons are solitary animal except during breeding although groups of dragons may gather to feed at a kill.
Mongooses have mutated cells that block the mambas' neurotoxins from entering their bloodstream. This makes them capable of surviving the venomous snake's deadly bite. (See how a mongoose fends off a lion.)
The sheep's body creates antibodies to fight the poison. The antibodies are extracted from the sheep, purified and used to create CroFab, also known as Ovine. Previously, venom was injected into horses, and their antibodies were used for antivenin.
Anti-venom is most often made from sheep's blood. The sheep swelled for about 2 days but the blood of the lamb destroyed the venom of the serpent.
Twenty minutes after being bitten you may be lose the ability to talk. After one hour you're probably comatose, and by six hours, without an antidote, you are dead. A person will experience "pain, paralysis and then death within six hours," says Damaris Rotich, the curator for the snake park in Nairobi.
