I'd be getting scared when a cat reaches the 20kg threshold. I'm about 90kg, so thats a 4.5x ratio :)
Cats are the perfect killing machines (apart from maybe sharks) :)
>"I'd be getting scared when a cat reaches the 20kg threshold" - most likely even 10kg cat will shred you before you could blink. They're insanely fast and surprisingly strong for size. Furry explosives they are
There's a bobcat that lives around here. He's on my porch now and then, and I also see its tracks in the snow.
It doesn't look like it wants to be petted. I stay clear.
