While watching my cat engaging in yet another battle with my shoelace, I noticed that he seemed mainly to use his left front paw. Do animals have a more dextrous side that they favor for particular tasks, just like humans? – Mike, Perth.
The short answer is: yes they do! Like humans, many animals tend to use one side of the body more than the other. This innate handedness (or footedness) is called behavioral or motor laterality.
The term laterality also refers to the primary use of the left or right hemispheres of the brain. The two halves of the animal brain are not exactly alike, and each hemisphere differs in function and anatomy. In general terms, the left hemisphere controls the right side of the body and the right hemisphere controls the left side.
