I don't know about rejeting after gerbils, but after those stinkin chinese mice built a nest in my air cleaner, well, that was the last straw.
Techie Tip; Gerbils love high caffeine/vitamin B energy drinks. Lean out your mixture when providing anything with more than 3 different B vitamins, otherwise the hamster/gerbil wheels bearings are likely to implode.
Also, three mice aren't really too bad, if they are blind. If not, you may have to do the conversion yourself.
I'm recently moved to Wisconsin, you know, the cheese state, so we have an overload of immigrant mice here taking up residence (and sometimes residents too) all over the place.
