Grey-tailed voles are very timid rodents. We must be careful not to scare the grey-tailed voles in our usual training, and we must have a certain amount of patience.

Give the grey-tailed vole a simple name, then give it a simple name every time it feeds Call out its name, and when it responds to you, feed it to the grey-tailed vole, and the grey-tailed vole will gradually become familiar with you.

After you get used to it, train the grey-tailed voles to lie on their hands. Lay the grey-tailed vole in the palm of your hand, then give it the snack, turn over and stop giving it, repeat it several times, so that the grey-tailed vole knows that you can eat the snack while lying down, so it just lays down obediently.
