Two legged cat is very special

Two-legged cat
I know this is a very short video but it shows an adaptation to two hind legs. She or he walks like a flightless bird almost. That’s not meant to sound insulting or derogatory. It is just the way she looks in the video. She makes that beautifully flighted jump with precision so that she lands with little forward momentum and softly.
How can a cat (approx. 5Kg) jump on my lap so gently that I donโt notice her arrival?
