This 28lbs cat is so big people think it's a dog

A huge two-stone cat from Russia that is thought to be the world's largest is so big it is often confused for a dog. Kefir, named after the fermented milk drink, is an oversized Maine Coon belonging to Yulia Minina in Stary Oskol. She bought Kefir nearly two years ago as a kitten and says the pet is still growing. Kefir even has the same weight as an average two-year-old child. The breed hails from the state of Maine in the US and is considered one of the oldest homegrown breeds in the country. On average, males weigh up to 18lbs while females weigh up to 12lbs.
