This isn't a joke:
The cat pictured, a very friendly stray named Manny, has learned to push the shutter release on a GoPro camera, and the resulting selfies tend to be pretty good. I swiped the photo above from an article entitled "This Selfie Taking Cat Takes Better Selfies Than You," which you can find here. It's full of additional cat photography and worth your time.
Apparently the cat likes to take walks with people and dogs. Instagram user @yoremahm is Manny's friend and has posted many more of Manny's photos.
