Mario, a cat from Green Falls, WI, has been trying for the past few months to lose a bit of holiday weight that he put on at the end of last year. According to friends, he’s been singularly dedicated to the task.

“I’ve never seen him so committed,” said one source close to the cat. “He’s basically cut out processed foods, he has a kale and goji berry smoothie every morning, and he’s even set up a gym in his basement.”

Friends report that Mario is seeing his weight tick down at a reasonable pace, but that he’s been frustrated by his workout routine.

“A trainer initially recommended spending some time on an exercise bike every day,” said the friend, “but Mario bought a top-of-the-line bike and sits on it daily. So far, though, it hasn’t had nearly as much effect as his healthy diet and daily walks.”
