Hi Hope 2020
There are lots of topics about rats. I’m not sure whether there was mention of pepermint oil in any of them, but you can find a list of them within this topic:

You might find you need to adapt what you’re feeding to something which the rats don’t like. i.e. some don’t like dried cat food (although others will cache it). But you could also try wet cat/dog food. But they might become accustomed to the smell of peppermit oil anyway after a bit, if they are hungry.
