The Mlem, Boop, And Blep: What Your Pets Are Really Doing

Understanding animals takes a language of its own. The weird and wonderful behaviors they exhibit from time to time are a large part of why we love them. There just aren't human words to cover them, so we are required to make some. In case you aren't up on the current popular vernacular, we're here to give you a handy visual aid!

What’s the difference between a blep and a mlem?
