I gave up in trying to stop the licking because I know it's not hurting me or her physically, although her tongue is one of the roughest I've ever felt in a cat.
It does gross me that cats lick their butts and us too, but being an "OWNER" that's just all part of having a cat. Now I just let her wash me down (except I still refuse to let her lick my face) and then I go wash. I admitted I lost the fight and battle on this one.
The cat was thoroughly checked by a vet to make sure she wasn't lacking vitamins or anything to cause the excessively licking, and all that was fine.
I had posted for any suggestions because I thought someone else might have experienced an excessive licker, and the posting about using hand lotions was something to consider, but that wasn't the problem either.
But, anyhow, things are going very well with our Mystery. We have just come to accept that she is a tongue-aholic and can't control her "licker". NO BID DEAL!
