Red pandas cubs are playful.

After three months of development in their mother, the cubs are born in late spring and early summer in nests made of grass and trees. Newborns typically have their eyes closed, their fur is quite thick, and it is a gray tint all over their bodies.

A red panda has difficulties throughout the first few weeks of life. Red panda pups are born in litters of one to four cubs, although a mother typically bears a pair of offspring. Prior to their eyes opening, newborn red pandas are groomed for weeks. They will begin to take on their distinctive reddish hue and deeper markings at a month of age.

The cubs often remain away from the nest until they are 3 months old, but they do not separate from their mother until the next mating season begins. Around three months old, they first leave the den, and it's not until four or five months old that they really begin to take control of their bodies.

Young pandas pounce and play not just for amusement but also to develop abilities like coordination and balance. Around two years old, red pandas are said to be fully developed and grow to the size of a fluffy house cat.
