way i got my garters when i kept them off worms and fish was scenting the mice with a worm and that got them eating 100% all the time. i slowly used less worm scent on the mice till the point of no scent.

I once in a while gave them fresh fish fillets from the market when i was making fish. But if you can get them on mice from scenting stick with that and youll be well on your way.

Heres a video of a gravid female i had who only ate mice.
