A chunky kitty who captured hearts on the Michigan Humane Society’s social media has been adopted.

Zack, a 30-pound cat, was adopted on Jan. 3, the humane society posted on Twitter.

At 30 pounds, Zach is about three times the size of the most common type of house cat, the domestic shorthair, said a veterinarian technician at Kalvig and Shorter, an animal hospital in New York City.

This absolute unit of a cat is Zack. He's available to adopt at our Howell shelter but needs a parent who will help him slim down. He's currently over 30 pounds and our medical staff is trying to get him to a healthier weight. https://bit.ly/2u7Ktad

His new family will help him on his weight-loss journey, reported ABC News’ Detroit affiliate WXYZ.

Overweight cats are susceptible to a host of diseases including diabetes, tumors and urinary tract infections. They also have problems grooming themselves.
