What are the pros / cons of keeping wild animals as domestic animals?
I think keeping wild animals as pets has many pros. I think that wild animals can become domesticated. Cats and dogs were also wild animals before, but became pets. I like to take home wild animals that are not very big. I can keep a lizard at home because its small. I can keep a small spider in the terarium at home.
I think keeping wild animals as pets has many cons. The main disadvantage is that the animal can attack. The case was when the tiger grew up and consumed the owners. A poisonous spider or snake can bite. A wild animal can not always live at home.
