While bow hunting:
Sitting on a stump cow calling and had one stalk up on me about 15 feet away. I had no idea how long it stared at the back of my head, no clue it was there until I stood up and it bounded off through the brush. There was a small drainage I was sitting right near so it used that to put the sneak on me. If it wanted me I'd have been toast, but like most archery hunters the cat didn't know what it was looking at when it snuck in expecting to find an Elk and instead found a human oblivious to it's presence. I use walkers game ears now, would have been nice to hear it sneaking in and got ready for a shot - opportunity to take a cat was lost.
Another was berry picking with 2 kids and a grandpa and a bird dog. had to ditch the atv's and decided to hoof it the rest of the way. Got about a 1/2 mile in (we underestimated the distance) and came across a big tom that must have just sprayed a tree. You could smell the cat piss wafting in the wind and sticking to your tongue - nasty!
My little Britt had no clue she was about to get eaten as she was heading up towards the cat, I had a tough time recalling her but she eventually came to me then I used a belt for a leash. We expected the cat to take off but instead it just sat there hidden behind a log. none of us were armed
We decided to head back to the Atv's and this cat stalked us the entire way, you could hear it just above us on a rocky ridge with brush breaks, occasionally it would break a branch giving away it's position as it kept pace with us. Eventually it went away (we thought) instead it had run ahead of us and set up an ambush on the trail we were using. it popped its head up out of the bushes just uphill from us. I rared back with a big stick getting ready to clobber it over the head, but it sat back down in the bushes and we eased past it (about 10 feet away)
I went back up the next morning with a ruger 44 carbine, it shat right in our tracks but didn't show itself.
I never go unarmed now. Irresponsible to do so now. I used to tromp through the woods pretty much every day as a kid, but there were no wolves and the bears/cats were chased with houndsmen so I was pretty safe if I didn't injure myself. Not so much now we have uneducated wolves, bears and cats and more grizz than ever.
I think you'd all be shocked if you knew how many grizz there are now.
