But there's indeed a big problem.
First of all, those golden cats are not pure wild animals. They have already adapted to captivity and artificial feeding. Bringing them into the wild, whether or not they'll unleash their instincts is uncertain, but they'll definitely feel scared.
Moreover, the place to build the animal shed must have a water source and enough facilities for sewage treatment and disinfection.
The emergency station is not as strict because most of the animals there are temporary residents. They'll be transferred to the animal shed area of the protection station for further treatment after surgery.
The animal sheds of the protection station had these issues considered during the initial design.
As for Jinya and them, the mountains and forests are so vast; everywhere could serve as their litter box, so Chen Ying doesn't need to worry about this issue.
