According to this article cats, dogs, parrots and even fish show a preference for using either their left or right hand (paw or fin). The discovery was made by a team of psychologists who had the great job of playing with 42 pet cats for a couple of weeks. It seems female cats favour their right paw whilst male cats prefer the left. It is suggested that hormones may play a part in the preference as the difference disappears when pets are neutered. It has also been found that parrots like to pick up objects with a dominant foot and fish have a preference to left or right when they dodge a predator. Having several cats I think I will be conducting some tests on their various paw preferences with the results to follow.
