I want to switch my hedgie's food from Purina Pro Plan Savor Adult Chicken & Rice Formula Dry Cat Food to Natural Balance Original Ultra Whole Body Health Cat Food because it seems a lot healthier than the one I'm feeding her now. But she just gave birth to four hoglets. When should I start switching her food? Should I start a little bit now so by the time the hoglets start weaning they'll be eating the new food? Or is it going to mess up with how the moms currently feeding the hoglets? I just need to know the best and healthiest way to go about this, please help!!
