The little piggies weigh just over half a pound at birth and only grow to 12 to 16 inches high, topping out at about 65 pounds - rather svelte in the pig world.
A cross between pot-bellied pigs and other breeds, these pigs are not cheap. One breeder sells pairs of them for $1100 each. As of now, teacup pigs are only sold in Britain.
