Shannon loves to lick people who’ve just had a shower. Catz don’t smell like soap!
I had a dog that did that. They do it because you don't smell like yourself after a shower (soap, shampoo, lotion...) and they want you to smell "normal."
My poor dog barked at me when I got out of the shower and dried off. He sniffed my legs in that "Whoa! What's this new smell?" pose, and decided I wasn't Mom.
