Carrie, how great to see you! And as usual, a wonderfully informative reply.

Lefty licks the rugs, the floor, the couch cushions, his bed, etc. He usually stops when I tell him to. However, I have switched several cleaning products because of his little "habit"--plain water for the floor, in a steam cleaner, and a mixture of baking soda and cornstarch for the rugs! I figure it's better for us humans, too.
