We gave one of our boys the title 'Dr' after he repeatedly and vigorously inspected sensitive body parts and openings including but not limited to: mouths, ears, belly buttons, groins, arm pits. He does not seem to be looking for anything specific either, he just likes doing check ups! haha. Our other boy Elijah loves my mouth. He will try to split my lips open with his sharp little claws and it is quite a fun activity constantly dragging him away.
