Cats or dogs, cats or dogs, cats or dogs ... can't we all just get along?

A new documentary, appropriately titled "Cat v. Dog,' gives us good news if you're dog lover, but not so much if you're a cat lover.

One neuroscientist reached deep down into the brains of each species to find our barky friends beat out their meowing foes when forced to battle it out.

Good thing I love both! That's just extra love for me!

To get those results, Doctor Paul Zak let cats and dogs play with their humans and then took blood samples.

After, he tested their oxytocin, which is a chemical produced "in the brain when we care about someone."

Dr. Z's analysis showed dogs produced more than four times the chemical than cats, AND only half the cats evaluated made it at all.

He reassures cat ladies and gents this is because tabbies are less social and more territorial, going on to say the exams were done in an area unfamiliar to both, but was probably more stressful on the felines.

So, another point for the pups, just goes to show it's a "ruff" dog eat dog world out there.
