Bima   : What animal is it, Dad?
Mr.Tio : It is a panda.
Bima   : Wow! It can climb and walk trees.
Mr.Tio : Yes. Some pandas are good tree climbers. They can climb trees from 7 months old.
Bima   : Wow! Why are they so big? Are they big eaters, Dad?
Mr.Tio : Yes, that's right. They can eat twelve kilos of bamboos every day.
Bima   : It is amazing. Do they live in groups, Dad?
Mr.Tio : No, they don't. They are solitary. Males generally live apart, except for in the short breeding season (March to May), when they compete for female attention. Females raise the cubs alone.
Bima   : Oh I see. I think both males and females raise their cubs together.
