On TV, animals with cute appearances and funny behaviors are always loved by everyone. However, few people have noticed that their homes are shrinking rapidly. This is why zoos need to exist-conservation, research, and the transmission of educational knowledge through entertainment. But if animals are kept for a long time, they will get depression! The team uses waste utilization and environmental sustainability to create toys that conform to animal instincts and habits, enrich animal behaviors and prevent stereotyped behaviors (depression). . In addition to improving the stereotyped behavior of animals, it also avoids negative ecological education. At the same time, because the zoo carries the conservation function, it enriches animal behaviors, reduces illness and death due to depression, and can also achieve the function of protecting biodiversity. We are not only creating toys for animals, we are also creating a suitable environment for animals to achieve ecological education. The value of education and environmental sustainability!
