If I were to mix some food up (probably a tofu mix) if the rats like it

would multi vitamins be beneficial or even needed?

From what I've read, if the rat is getting enough of the right kind of foods in their diet, then they shouldn't need the extra vitamins.

Exactly. Not needed. Beyond that, I'd be weary that you may be adding too much of something.

Rats LOVE tofu, btw! Just make sure it's packaged raw tofu and not raw bulk tofu, which can contain bacteria.

If you want to make that food their staple diet then yes. You need to research what the rats daily required amount are in vitamins, minerals, macro minerals, amino acids and so on.
