Sure, there's the downward dog. And there's even the cat pose. But names aside, why is it that when you unfurl your yoga mat, your pets come running?

There are a lot of reasons your furry BFF might want to participate in your yoga routine. First, there's the simple idea of quality bonding time. Where you are, your dog (and sometimes cat) wants to be, too. Even if that means contorted positions on the floor.

Plus, that spongy mat is really appealing. It's soft and squishy and, for dogs especially, it has a tempting odor: you.

"You lay down on it, you sweat on it, you rub your body along it as you do cobra and upward dog," writes Lexi Pandell in Wired. "And, most likely, you don’t wipe it down after every single yoga session. For a dog, it is a smelly, hormone-drenched B.O. sponge. And, because they love you, they love your stank."

Cat rescue founder and blogger Pamela Merritt explains the appeal of yoga to feline practitioners, "What is it with cats and floor exercises? It’s pretty simple. We get down on the floor and we act like cats. No wonder we become so completely and utterly irresistible."

Here's a look at some yoga partners who made the practice a little more difficult, but definitely a lot more interesting. Like this dog, who really seems to know what he's doing.

Just like the rest of your family, your pets want to encourage healthy behavior — so keep up the yoga!

Dogs and cats can't help themselves when you unroll the yoga mat. They either participate or just get in the way.
