Most Chinese cities like Shanghai sell these outside train stations.

There have been reports of animals being killed inside animal keychains.
For a seller referenced how people have to remove animals from the bag after 3 days if they want them to survive. Therefore, they couldn’t simply handle being full into a little plastic with no way of food and air. The majority of the squishy toys are creatures of land and water. So, they need equivalent time on the land as they do in the water.

Despite the fact that there are a few petitions proceeding to stop this heartless practice, these animal keychains continue getting sold all over. This has been viewed as a significant fever among young people. Also, there isn’t a lot of chance that this activity would be banned.
Dr. Sam Walton from the Universiti Malaysia Terengganu explained how the excretions and the breath of the animals itself can kill them. He told The Star Online, that despite the fact that there may be satisfactory oxygen in the plastic, the animals are going to harm themselves with smelling salts. Such sea-going animals are very vulnerable to temperature changes. As it implies that being in a bag like this is most likely equivalent to being in a nursery for them. The animal keychain is just going to shake them around so much, that they will kick the bucket before starvation or suffocation becomes an integral factor.
Interestingly, China did sign a draft in 2009 that proposed animal security.
However, it has not been executed with full power. Thus, very little has been accomplished from that point forward. However, there is a relentless ascent for animal rights over the most recent couple of years. And plenty of animal shelters being taken up to spare animals like dogs and cats.
The Shanghaiist claims that they provide the animals with food that can make them survive for 3 months. However, is it not ensured that the animal would handle 3 months in those keychains.
