Pandas always live in cold, wet climates. They therefore give birth to their young in places such as caves. Their cubs, which are like tiny, cute toys are blind and toothless when first born. The cubs are usually born around September and are 10 cm long and weigh just 142 grams. Eight hundred times smaller than their mothers when first born, they grow very quickly, reaching 27 kilos in just nine months, whereas it takes us at least six years to reach 27 kilos.
