Kissing isn't distinct to humans. Tons of animals like to express affection with a peck on the lips…or face…or whatever they can reach, really. It's all good!
“Sit still so I can love you!”
Okay, this is just unbearably cute Feeling mushy yet?
Take note: be less grumpy or you're getting kissed in the eye
Ooh, inter-species smooch
Huh, apparently dogs are irresistible
Who can bend like that? Who cares!
