Dear Dhruv
 
lets take an example of  ball hitting the door – 
 
if you treat the ball+door as an isolated system. The angular momentum of that system must be preserved as well. If a system is not rigid you can have: -
  1. Non zero net angular momentum without rotation (as the ball+door shows) -
  2. Rotation with zero net angular momentum (as the falling cat shows)
