Lucca, a blue patched tabby and white cat, licks a sheepskin rug as she cleans her front legs with her eyes closed. In this image she's just starting to lick a long strand of the rug, and her tongue is stretched out with rug strands on it. Her tongue is extended, showing the filiform papillae (spines or barbs) on the top surface of the tongue. See the next image for some tongue acrobatics!
