What It Is and Key Specs
Wysong Ferret Epigen 90 is a 5.63-pound bag of extruded dry kibble marketed as the first starch-free ferret diet of its kind. The "90" in the name refers to the brand's claim that roughly 90% of the formula's caloric contribution comes from meat and fat sources. According to the Wysong product page (wysong.net), the ingredient list opens with Chicken Meal, Organic Chicken, and Meat Protein Isolate, followed by Chicken Fat (preserved with Mixed Tocopherols), Gelatin, Natural Flavor, Coconut Oil, Dried Natural Meat Broth, Chia Seeds, Calcium Carbonate, Taurine, and Calcium Propionate as a preservative.
Wysong positions the formula against "grain-free" competitors, arguing that grain-free does not necessarily mean starch-free, and that Epigen goes further by removing starches — the carbohydrates that extrusion typically requires — altogether. The brand describes this as making the food more closely resemble what ferrets are biologically designed to consume.
The standard Epigen 90 is the more nutrient-dense version in the lineup. Wysong also offers a Ferret Epigen 90 Digestive Support variant, which the company describes as "slightly less concentrated," carrying 62% protein and 16% fat (wysong.net/products/ferret-epigen-90-digestive-support).
Beyond the protein-forward base, Wysong states the food includes probiotics, prebiotics, enzymes, phytonutrients, nutraceuticals, natural-form antioxidants, vitamins, and minerals, as well as omega-3 fatty acids and other essential fatty acids. Taurine — an amino acid critical to ferret cardiac and retinal health — appears explicitly on the ingredient panel. Chia seeds contribute an additional plant-based omega-3 source.
An independent analysis at
ferret.love notes that the combined protein and fat content reaches approximately 80%, which the site characterizes as notably higher than typical kibbles that usually land in the 50–60% range (

Build Quality and Safety
The kibble is produced by Wysong, a manufacturer with a long-standing focus on carnivore-appropriate pet nutrition. No product recalls or CPSC safety actions are referenced in the available sources for this specific product. Calcium Propionate is listed as a preservative — a synthetic additive, though it is widely used and recognized as safe in pet foods. Owners introducing the food for the first time are directed by Wysong to follow transition instructions on the product label, which is standard guidance for any dietary change.
Real-World Fit: Who It Suits, Who Should Skip
This food is best suited to ferret owners who prioritize a meat-first, low-carbohydrate diet and are comfortable with a premium kibble price point. The high nutrient density means ferrets may consume smaller portions by volume, which some owners find economical over time. The 4.6/5 aggregate from 1,729 Amazon readers suggests broad satisfaction, with owners citing palatability and digestibility as positives.
However, community-level discussion tells a more nuanced story. The Holistic Ferret Forum includes documented cases of ferrets — particularly those with sensitive or compromised digestive systems such as IBS — experiencing loose or liquid stool on the standard Epigen 90 formulation (
holisticferret60.proboards.com). The
ferret.love analysis echoes this, noting that some ferrets have been known to have issues digesting Wysong, especially the regular Epigen 90 variant. Ferrets with known gastrointestinal sensitivities may fare better on the Digestive Support version or an alternative format such as freeze-dried or canned foods.
Honest Limitations
- Digestive sensitivity risk: A subset of ferrets, particularly those with IBS or sensitive stomachs, have reported soft or liquid stool on the standard formula. A slow transition period and close monitoring are advisable.
- Single protein source dominance: The formula is heavily chicken-based. Ferret owners practicing dietary variety or managing chicken sensitivities will need to rotate with other proteins.
- Synthetic preservative: Calcium Propionate is present; owners preferring preservative-free diets may prefer formats like freeze-dried raw.
- Kibble format limitations: Even the most meat-dense extruded kibble is still a processed food. Owners seeking the least-processed option may find freeze-dried or raw diets a closer match to whole-prey feeding.
