Do mammals have a handedness preference like humans?

I don't think I wrote the title correctly, so what I mean is, do mammals have a preference on which hand they will use? For example, when cats are touching something, do they have a preference of which hand they're going to use or they use which ever is closer/easier to use?

Paw or hand preference is common.  It seems to appear in pretty much all mammals that use their forelimbs for things other than locomotion.  However the distribution is 50/50, with half being left handed and half right handed.

The only animals known to display a lateral preference at the population level are humans (right handed) and some species of parrots (left footed).  Some theorize that the lateral preference could be caused by language specialization in one hemisphere of the brain.
