Marshall Senior Ferret Diet (4 lb) – A 4-pound bag of premium ferret food formulated for older ferrets (around 4 years and up) or those who are less active. This senior diet is slightly lower in fat and protein than the regular formula, to help prevent weight gain in slower-metabolism ferrets, while still providing plenty of nutrition. It includes added ingredients to support joint health and antioxidant vitamins for immune support. The kibble is highly digestible and easy on sensitive stomachs. By feeding this to your senior ferret, you help them maintain a healthy weight and energy level, and support their overall health as they age.
