Here is a guy that seems to have let his guard down and paid the price.
From the article:
"The poor man, he loved his animals," (Deputy Coroner) Straka said. "They were his pets."The guy forgot that large animals can easily kill or maim you, on purpose or by accident. I know a guy that raises cattle and he was almost killed when a cow suddenly moved sideways and pinned him against a fence in his feedlot and almost squished him through the fence. He wasn't sure if she was pushed out of the way by a more aggressive cow or if she decided to scratch herself on the fence. Either way he could have ended up badly injured or killed. After that he decided to always carry a cattle prod with him when he worked in a close area with his cattle.
Be especially cautious if an animal is injured or is a mother with little ones. Mothers sometimes decide they don't want you too close to their young and a cow or pig is big enough to do something about it.
When my dad was a boy he went with his dad to pick up a bull. Grandpa towed an open-top cattle trailer over to the place behind his car and backed the trailer up to a chute so they could load the bull. My dad will playing in the back seat of the car. At first the bull decided that he didn't want to go into the chute. That provided some moments of excitement for Grandpa and the seller, but since my dad was inside the car my grandpa wasn't worried about him. Finally, after some effort on the part of the men the bull decided he would go into the chute after all. He was so enthusiastic that he charged through the chute onto the trailer and then jumped over the front end of the trailer and onto the trunk of the car.
My dad recommends against sitting in the back seat of a car when a bull jumps onto the trunk. Of course if the bull had covered a few more feet in the air before he landed then I might not be here to type this drivel.
The moral of the story: Barnyard animals are unpredictable.
It doesn't matter if you think they are pets. They can still kill you.
