I assume you mean gauranlen moss, which has no nutrition, so no, they cant eat moss, and yes, you should auto cut it if you want nutrition on those tiles..

....or he could mean the moss in jungle or cloud forest terrain to which the answer is the same.
Moss is edible but provide very little increase in the food bar.
