I'm not here to ignite any kind of "cats are better than dogs" debate, but you know who would probably ascribe to that line of thinking? Mark Ruffalo [1]. Unlike his fellow Avenger, noted Dog Person Chris Evans [2], Ruffalo's Instagram grid is filled with kitties. Over the years, he's posted various pics of current and past feline friends Biscotti, Magnus, Hansel, Felix, and Inky. He's even credited daughter Odette [3] with some of the still photography!

Read on to see some of Ruffalo's greatest cat moments, and when you're done, introduce yourself to Henry Cavill's giant dog, Kal [4]. (There is room to like cats and dogs, people!)
