No pets at the moment but planning to get another bitsa when the kids can look after it.
I'm with you 'Flippedy'. Some people just don't get it with cats.
When I was a kid my old man started feeding this feral tabby that was hanging around. After a while it became tame enough to handle. It was very big. It got to 10kg (not fat) and when curled up on my dads favourite chair, occupied the whole seat.
I used to play rough with it and it would respond in kind. If you played nice, it would bite without breaking the skin and kick with claws withdrawn but if you hurt it it, it would hurt you. I trained it to attack me and it would jump up as high as it could, latch onto my leg and kick with no claws, then run away to regroup and do it all again. This evolved into it hiding in the garden then stalking and attacking any family member that went out to garden. It caught my mum unprepared a couple of times.
One day a mate of my dads came over and the cat was sitting in the driveway. I had been rumbling the cat for a while and it was pretty aggro. He saw me rumbling the cat as he arrived and decided to have a go. I warned him that it might not be a good idea, but I was just a kid. If he could have read cat body language he wouldn't have gone near it. The cat didn't know him that well and as he leaned over and reached out, the cat leaped up, teeth, claws and all, latched on and ripped his arm. 10kg of angry cat hanging off him. He didn't ever try that again.
