How high can a cat jump down from?

i dont know how high they can exactly jump from but my cat has got a habbit of jumping out of my bedroom window to the floor with no problem at all so i think they could jump from much higher objects

I really don't know how high a cat can jump down from. However, I do know that one of our cats once jumped out of a window on the second floor - something like 20 - 30 feet on to a stone paved yard. We all rushed outside expecting to find the cat splattered all over the yard, but she was perfectly fine, strolling away down the yard when we all got outside. At another time, another one of our cats, might even have been the same cat, got itself stuck at the top of a telephone pole which must have been at least 40 feet high. My mother's comment was "It got it'self up there, it can get it'self down" Eventually it just jumped off, but not all the way to the ground. There was a hawthorn hedge near the pole and the cat jumped off into the hedge. Considering that hawthorn bristles with thorns, it seemed to be able to do this without getting itself turned into a pincushion - which was a minor miracle in itself.

not because of that, but because they spread out and their skin catchs and slows their fall slightly, then they are very flexable so when they land they often survive, but that the critical word is "survive" they are hurt, often seriously.
