Yes, though it is an uncertain thing, but in general, I believe that they do. Arthritis that comes with age causes the bones to ache, and maybe even to swell, and I believe that the knuckles are not an exception.
Whether certain people's knuckles swell/grow larger is relative one's personal lifestyle, but cracking them may very well increase the size of your knuckles later on, if not just hasten the arthritis in them alone.
Some people say that it can cause arthritis, but this is untrue. Cracking your knuckles can cause your knuckles to grow larger though.

There is no relationship between knucle craking and RA.

No bats do not have knuckles, they have no hands, so therefore no knuckles.
