Are you able to get hold of f/t gerbils as feeders or do you know someone who has a gerbil and will give you some bedding that you can roll an f/t mouse or rat in? Might be an idea before you try feeding live or take hom to the vet... My Royal female (8 yr old, CB) has gone 6 mnths without eating which was a bit worrying (she will often go 2 without eating...) but then one day she started to exhibit feeding behaviour, I offered her a f/t gerbil the next day and she ate it straight away. Just an idea.
