He wanted to keep them as pets.
Discussion:
There are new members of my brother’s companion animals. The female’s name is Chila and Chilo is the name of male one. My brother brought them home last week. I thought that they were mice, but he explained that they are not. Perhaps when you see them, you will thank the same way.
The reasons my brother choosing them was because they have the average lifespan of 10 to 15 years and they are quite small. They can be good companions.
