Luckily we don't get rattlers over my way, just some of most venomous snake in the world instead and they are silent.

Rattlesnakes aren't always deadly of course. Neither are black widows, tarantulas, most scorpions or Gila monsters. Several people I know have dogs who've been snake bit on the nose.

I got stung by a scorpion myself once on the 1st overnight of a two week vacation. A sting or bite just tends to be painful and unpleasant. And the mouth and teeth of a Gila monster are so small about the only way they could get you is by grabbing the flap of skin at the base of your thumb and chewing. No awake person is in serious danger. Ha, ha.

About the only person I know of to die from a local animal bite was the father of a Navajo friend who died of Bubonic plague from a flea bite -- a different threat altogether.

My friend died of COVID last year, BTW. He spent time on a ventilator, thought he'd recovered, then died of a heart attack about a week later. There are many things that can kill you that are much harder to see coming (Captain Obvious speaking).

@RichCC Well don't get bitten by any of our venomous snakes then, chance are if you are more than 30 minutes from Medical help you'd best be planning your funeral.
As for our spiders, the Sydney Funnel is a nasty little eight legged beastie with a venomous bite and attitude to boot, the Aussie Red-back Spider, the FEMALE is the one to watch out for, her bite may not kill but, trust, it WILL make wish it had.
