Ralph, a four-year-old Continental Giant rabbit from Sussex, has been named the world's largest bunny by Guinness World Records - a title which he also held in 2010 until a rabbit named Darius, of the same breed, outweighed him. Ralph comes from a long line of record-holders.
Size. While many people think rabbits are about the size of a cat, some rabbit species, such as the jackrabbit, can grow to be as big as a small child. Small rabbit species can be as little as 8 inches(20 centimeters) in length and weigh less than a pound. Larger rabbits grow to 20 inches (50 cm) and more than 4 pounds(1.8 kilograms). The world's largest rabbit clocked in at 4 feet 3 inches (129.54 cm) and 49 pounds (22 kg). The largest rabbit breeds are checkered giant, Flemish giant, French lop and giant chinchilla.
