Nutrition Philosophy

We believe in the strong human-animal bond that has driven us to become the world’s foremost authority on ferret nutrition. We’re constantly pushing for the highest quality ingredients for our diet and are always seeking ways to serve our customers and their pets better. Feeding a ferret a high-quality diet can help extend the life of your ferrets. We’ve seen it first hand because we’ve tried all other brands on the market.

It’s our goal is to provide you and your ferret a high-protein diet that’s easily digestible and delivers the highest amount of nutrition. Each ingredient is sourced in the United States.

How We Do It

We’ve done our research. Our diet was developed by a respected team of veterinarians, nutritionists, and ferret experts. It has a high protein content and ideal balance of essential amino acids, making it the perfect diet for ferrets in all stages of life.

Our diet is hand-crafted in small batches using a patented low heat process that retains vital nutrients that other diets don’t. We also use fresh chicken. In fact, it takes 3 lbs of fresh chicken to make every 4 lb bag.

Did you know?

Did you know that most other ferret food is made in huge batches and stored in warehouses for months at a time? Most of our bags of diet that you find in the store were made within 30 days of the purchase, so freshness is always guaranteed.

Key ingredients that we use in our food and why

Chicken Icon Chicken

Our first three ingredients are chicken. We use chicken by-products (organs only) because the amino acids are more prevalent in the organ meats than any part of the chicken. Organ meats also mimic a ferret’s diet in the wild. Animals of prey usually pick body parts to balance their nutritional intake.

Corn Meal Icon Corn Meal

In long-term studies, corn provides a strong complement to protein sources while also promoting digestive health. We use corn as a binder to keep the pellets from breaking down in the package. It’s a small amount compared to our key ingredient, chicken, and it will not harm your ferret.

Beet Icon Dried Beet Pulp

Beet Pulp is considered to be the finest source of fiber for ferrets. It contains both soluble and insoluble fiber to help support a healthy digestive system.

We know that every ferret is different. That’s why we offer three high-quality foods for complete and balanced nutrition for every stage of your ferret’s life.

We’ve increased the amount of poultry to enhance ferrets’ growth and overall health while limiting concerns about odor. The increased amino acid profile improves digestibility, and the new formula maintains the highest level of quality and freshness that Marshall Pet customers have come to expect.
