There is actually some research on this and yes cats and dogs often have a preference for which side they favor. The distribution is far more even than it is with humans and many more are ambilateral and work well with either side without showing a strong preference.
More interesting than cats and dogs are chickens and pigs. Most chickens don’t have a strong preference but those that do have a dominant eye tend to react to visual stimuli faster than other chickens. Pigs often have a dominant side of their about and it often corresponds with the direction their tails spiral.
