Ginger is on a diet

She is about 18 months old and you are meant to breed them well before that, at something like 6-8 months. Otherwise it can become hard for them to get pregnant because they get fat (their bodies count on them pretty much always being pregnant or feeding a litter) and apparently it settles round the reproductive organs. She is feeling quite chunky, so I thought maybe it would help if she was a bit thinner overall. She is not happy, but it is get pregnant or be eaten!
