Experts say that panda babies being born so tiny is caused by evolution that they underwent million years ago. The experts also believe that the giant pandas change themselves from the typical bears that eat meat to the bears that eat bamboo.

Furthermore, the lack of nutrients in bamboo causes a delay in the growth of the baby. The nutrients are only enough for the mother panda to keep going on a daily basis. Therefore, only a small amount of nutrients goes for the baby.

Yes, perhaps we can say that a newborn giant panda is smaller than a full-grown mouse. However, there is more to know about it. So, let’s have an overview of the size of these animals.

The newborn baby panda is around 15 to 17 cm, while a full-grown mouse is around 20 cm. So, if we will compare both in newborn conditions, we can say that the baby mouse is smaller than a baby panda. The same is true if we will compare both in terms of full-grown condition.
