What is stimulation for a panda?

As with other bears, a female would be a sow, a male is a boar, and a baby is a cub. But the male and female terms are less used than just the terms "male bear" and "female bear."

yes they do

Well... If it is a family then no. but if they hate each other then maybe they will just be careful when your hunting animals because some pandas are fighting and they might see you.. So they get too...

they communicate by poopin and pee'in on trees to say,"this is my territory" to other pandas, like dogs do

There are usually only about 2, 3, or 4. Mother, cub (1 or 2 of them), and the father(usually doesn't hang out with the mother and cub)
