Cat grooming her sister
Lucca, a blue patched tabby and white cat, licks Kira, a brown tabby. I love it when cats curl up together on a couch and groom each other! Lucca's eyes are closed while her tongue is extended, which clearly shows the filiform papillae (spines or barbs) on the top surface of the tongue. Her nose, whiskers, fur, and closed eyes are also clearly in focus.
