Left-handed pets....

SCIENTISTS have discovered that most pets — including cats, dogs, parrots and even fish — are right or left-”handed”. They prefer using one paw, foot or eye over the other.

Researchers previously assumed that the trait of being left or right-handed — known as lateralisation — was confined to humans, and that animals were ambidextrous. They have now found that nearly every creature has evolved to specialise in using one side over the other.

In cats, scientists have concluded that females tend to favour their right paw when trying to extract a treat from a jar, while toms favour their left. The same gender divide applies in dogs.

Fish tend to have a dominant eye when looking at potential predators. Right-eyed fish circle threats clockwise and left-eyed fish move anti-clockwise.
