When it comes to tigers, many people are afraid of the wind, but there is a lot less fear of tigers in zoos. Because they have been locked up for a long time, some of their habits have been tempered.
For tigers, food and drink in zoos, but it's boring. Look at this little story shared by the next Internet player. It's amazing.

The tiger in this zoo may be locked up for a long time, so it's not mean at all. It's like a big cat, and it's bad for its physical and mental well-being.
So, in order to keep the tiger alive and inspire the beast on its body, the breeder threw a dog into the tiger's garden to feed it, thinking that the tiger would be able to rejuvenate itself with the provocation of the dog.
But when the breeders read it the next day, the ending turned, and the scene seemed a little confused: what is this? Only the dog was alive and beaten down. Tigers lie on the ground and they're smug, like begging for mercy.
Ming, the veterinarian, thought the tiger was playing with the dog. He was locked up in a cage every day.

In fact, humans can't judge right or wrong by keeping animals locked up for objective reward. On the one hand, for animals that are not normally visible, and on the other, for their safety, many animals are now endangered species and could be extinct if they are not protected.
But for animals, they're locked up every day. Why don't they just eat and die? In particular, animals such as tigers and lions, which were at the top of the food chain, enjoyed hunting and freedom, but could not do anything after being locked up and could only grow old alone.
