See Explanation Below

Explanation:

Question seem incomplete.

However, I'll explain the idiom and also give example.

When the idiom is used, it is used for somebody who always escape even after engaging in a lot of wrong activities without being caught or punished

To have nine lives means to always get out of extreme difficulty and dangerous occurrence without getting hurt and also having the endurance to survive despite having a near encounter with death or disaster.

It can also be said to someone who goes to a near death situation and then survives without much bodily damage.

An example is when you try to tell someone to buckle up for difficult situations as used below;

"a cat has nine lives, but you have only one; so buckle up"
