THE world’s biggest bunny is preparing to see his heavyweight title challenged — by his giant son.

    Darius, who measures over 4 feet (122 cm) long and weighs in at a whopping 3.5 stone (22.2 kg), is officially the world’s biggest rabbit.

    But his title is now being contended by his son Jeff, who already measures 3ft 8in (111 cm) — with six months left of growing to do.

    The rabbits’ owner, Annette Edwards, 63, from Bromsgrove, in Britain, said she looks forward to the day when Jeff dwarfs his father.

    It costs her £5,000 (US$7,441) a year to feed her giant bunnies as they munch their way through 2,000 carrots and 700 apples.

    The pair both also eat a huge dog bowl full of specialist rabbit food every day, and a bale of hay a week.

    Edwards said: “Although the pair of them are huge, they’re the best animal friends I could ask for.

    “As soon as I think he’s made it, he’ll be measured by his vet and then Guinness will certify that he is the biggest rabbit in the world.

    “Even though they’re so big, they are very low upkeep. They really do look after themselves most of the time. They run free in the garden during the day and at night go to sleep in their cozy crates.”(SD-Agencies)
