Why animals should be kept in cages?

In some cases, it is for the animals protection. For example, if they have caught a tiger that they wish to move to a safer habitat, having the tiger in a cage makes it safe for both the animal and people. Or if it is injured, and should be kept still as possible for healing purposes, it is better they have a confined area. But this should not be for the rest of the animals life. Animals were never meant to be in cages, they were meant to live on earth as humans are.

i completely disagree i think animals should run free without fences or people live a life freedom
