The animal charity, the PDSA, wants to find out how many of the nation's cats, dogs and other pets favour their left limbs while going about their daily business.
According to their recent press release, PDSA senior vet, Sean Wensley, said: "There is evidence of 'handedness' – preferring one side of the body to the other for certain tasks – in chimps, walruses and crows, so it's plausible that the same could be true of our pets."
