Cat-and dog-owners already know that their beloved animals are completely different from each other, but scientists now have more evidence that relates to how our furry friends lap up liquids. While dogs plunk their tongues in water to scoop it up and fill their cheeks, cats use two physical forces—gravity and inertia—to delicately suck up liquids with just the tip of their tongue. Much like elephant trunks and octopus arms, cat’s tongues are remarkably agile given the lack of skeletal support. Therefore, the findings may provide new inspiration for soft robotics technology.
