Kefir is not even two years old yet, but he already looks like he could eat a horse for dinner every day, and we can only imagine what it must feel like for his owner to anger this beast. In reality, this giant fluffball is just a tender cuddle monster. Even as a kitten, he was larger than an ordinary domestic cat. Now he weighs over 30 lbs, and there’s still time to grow! An adult Maine Coon grows up to 4 ft in length, including the fluffy tail, and Kefir is up there already.
