I've just spoken to the reptile specialist I get my rats from and he has some frozen gerbils that I'm going to try. He also suggested I try a product called Avipro Plus. It's a probiotic that should stimulate appetite. Here's some info on it: https://www.thereptileroom.co.uk/cat...047f84dc866fd0

Has anybody heard of or used anything similar? Anyway, I'm heading in to pick up the Avipro and a gerbil or two.
