No! I shouldn't laugh but I did.
I once saw our cat jump from a wall over six foot high out and upwards to a metal bar 2 to3ins wide at the most. This was part of the frame supporting the fire escape ladder which went up to our third floor flat.
There was a large cat he did not like, sitting at the bottom.
I could see Frank (Our cat) eying up the jump, preparing to go for it in that wiggly cat bottom way they do. I was terrified but did not want to put him off his aim.
He made it onto the bar! Walked round the side very nonchalantly and trotted up the steps. I think we both lost a life there.
