How to feed slugs? In the cage, okay? Will it fly away if you let it go?

Whether you can let go depends mainly on whether your slug is wild or artificially propagated.

The iron slug I bought last week is artificially propagated.

Basically stable. Do not jump. Do not jump.

However, because I am used to receiving food from people.

So I basically bite when I touch something. ...

There are photos in my Baidu space. I just took it.

If you feed it, as long as it is food with less water.

You can feed them.

Carrots, melon seeds, peanuts, Tenebrio molitor, crickets, cockroaches, cooked meat.

Sometimes I electrocute a fly with an electric mosquito swatter and give it as a snack.

In short, never feed water or food with high water content.
