In my youth I witnessed a smallish adult puma (mountain lion) successfully harvest a nearly adult cow elk while I was hiding. I was also hunting, but focused on a bull elk somewhat further from me. It was astonishing the speed and total quantity of violence that an 80-100lb cat delivered in only a few seconds on nearly 500lbs of prey. The cat had an alomost perfect attack angle, and the combination of slash, grip, puncture, and throttle toppled the cow elk, and it ran out of resistance in very short order. I had not even seen the puma before the attack started, and I expect a trained attack housecat would practically appear out of nowhere - from behind a couch or a curtain or off the top of a refrigerator, and it would become an 'I need stitches' situation too easily.
Its probably a good thing that most housecats are pretty much impossible to train beyond 'use a litterbox' and 'stay off the kitchen counters', if even that.
My cat is very well trained to have his harness put on, since he knows it means going outside. He'll jump on the stool and give me a "hurry up already" look and a meow if I don't move fast enough.
The first time I put it on was not so... inviting, though it was a great impression of a Tasmanian devil.
lol moment was when we with a girlfriend playfully fell down on sofa, but the then master-of-house siberian 6kg cat considered that a threat to me.
he jumped ~3m claws open, smashed a desk top lamp, shredded the gfs' top and basically opened up her back before I could stop him.
If you choose to trail run in mountain lion country, a bell may scare off bears, but may have the opposite effect for mountain lions. Stay aware, don't wear headphones or zone out on the trail.
I have seen three separate stalk and harvest events, the cow elk was my first and closest. My second was a wild burro colt. The the third was an old javelina (collared peccary). The second was by far the scariest, as the puma actually bit over the mouth and nose of the colt and suffocated it.
Fear is the correct emotion with regards to these wild animals. If you want to see one, the Arizona Sonora Desert Museum (really a zoo, in spite of the name) is the best and safest way I know about. I would never willingly try to find one in the wild unless i had a hunting permit for one, and I'm not inclined to do that.

Getting old now, so walking in the woods alone is something I don't do anymore, even though things are a lot more developed nearby.
