Rosewood Natural Eats Ferret Bites Chicken & Liver. Ferrets have specific dietary and care demands, and their owners are passionate about ensuring they use the best products, made specifically for their pets. There are many good main diets for ferrets, but the few treats that are available are typically poor quality due to the use of high amounts of vegetable-based and sugar-rich ingredients, dairy products and added salt. Our new Chicken & Liver Bites are the first UK branded treats to remedy this with 69% of the treat being chicken meat, fat, liver and egg. These are irresistibly tasty, semi-moist treats that ferrets and their owners will keep coming back for.
