When I was operating heavy equip. in the eighties a dump truck driver showed up on the job and during a brief BS session another crew member told me to go look in his truck cab at his cat inside. I stepped up on the running board figuring to see a Persian or something but when I looked down there was a full grown 160lb. mountain lion curled up asleep on the seat below...Whoa. He rode around in that crazy [beeep]'s truck with him until he ripped mouthfuls of foam out of the seat one day. We went over to his house once after work and his big cat named Apache was in a chain link pen in the backyard. As a prank we didn't tell another crew member about the cat and the owner brought him in the house on a leash and that lion let loose the classic 'crazy woman' scream. The target of the joke went over the coffee table and took the front screen door with him running out of the house. Off the leash that cat then proceeded to run horizonatally along the walls screaming, like a daredevil motor cyclist inside the 'wall of death', happy to come in. Even though he was declawed I remember I sat down on the couch trying to be inconspicuos (sp)and he finally came up and hissed in my face. He didn't like being ignored. I sparred with him and he hit hard, but when he realized you weren't afraid of him it confused him. He was cool. He left perfect wet tracks on the hardwood floor as the owner explained big cats perspire through their feet. He said he got loose once and ran down and killed a domestic cat in a heartbeat. That instincts probably carried over from the wild when they encounter a bobcat.
I also had a pet boar 'coon named Jesse as a kid. An hysterical neighbor lady called one evening asking if I would come get my pet 'raccoon'. When I got there there was a formal cocktail party going on and Jesse was on a wrecked buffet table with food all over the floor, washing his hands in the punch bowl as terrified guests stood at a distance. He never did like to share. Some drunk woman thought he was cute begging at the back patio door and had let him in.
