Wysong Epigen 90 is known for its very high protein content and starch-free design. It’s marketed for dogs, cats and ferrets, and ferret owners looking for a lower-carbohydrate kibble often consider it. This review covers what it is, its documented pros and cons, and what to weigh before switching.
The Short Answer: Wysong Epigen 90 is an unusually high-protein, starch-free dry food that many ferret owners choose to reduce carbohydrates. That design aligns with ferrets’ carnivore biology. Its very hard, dense texture, higher cost and the need for a slow transition are common drawbacks. Talk to your vet, especially if your ferret has kidney or other health problems.
Key Details
| Feature | Details |
|---|---|
| Type | Dry food, starch-free |
| Protein | Very high (check current label) |
| Marketed for | Dogs, cats and ferrets |
| Carbohydrates | Formulated without starch |
| Texture | Dense, hard kibble |
What It Is and How It Works
Most dry foods need starch to form kibble. Wysong uses a different process to produce a starch-free kibble with a very high protein level. For ferrets, which are obligate carnivores, lower-carbohydrate diets are often recommended, particularly for those prone to or diagnosed with insulinoma.
Because it’s so protein-dense, it’s not a typical “complete” food for every animal or situation. Check the label for its feeding statement and life-stage claim, and confirm with your vet that it suits your ferret.

How to Transition a Ferret to Epigen 90
Ferrets can be stubborn about new foods, and Epigen’s texture is very different from most kibbles:
- Mix a small amount into your ferret’s current food.
- Increase the proportion slowly over 3 to 4 weeks.
- Try lightly crushing or soaking the kibble in warm water at first.
- Weigh your ferret weekly to make sure it’s eating enough.
- Never let a ferret go without food for long, since ferrets need frequent meals.
If your ferret refuses it entirely, a different high-protein ferret food may be a better choice.
Things to Consider Before Buying
- Ask your vet before switching, especially if your ferret has kidney disease or other conditions.
- Check the label’s life-stage and feeding statement.
- Transition slowly and monitor weight.
- Provide plenty of fresh water.
- Watch stool quality during the switch.

Frequently Asked Questions
Is Epigen 90 good for ferrets with insulinoma?
Many owners use low-carbohydrate foods for insulinoma, but your vet should guide diet and medication.
Why is Epigen 90 so hard?
Its starch-free process creates a dense kibble. Soaking can help.
Can Epigen be the only food?
Check the current label’s feeding statement and talk to your vet.
Is it more expensive?
It often costs more per pound than standard kibbles.
Can I mix it with other ferret foods?
Yes. Many owners feed it as part of a mix.
Is high protein bad for kidneys?
Healthy ferrets need high protein, but animals with kidney disease may need adjustments. Ask your vet.
How much Epigen 90 should I feed my ferret?
Follow the feeding guide on the bag as a starting point, then adjust to your ferret’s weight and body condition. Ferrets eat many small meals, so most owners leave food available throughout the day. Weigh your ferret regularly when you change foods.
Does Epigen 90 cause dental problems?
There’s no strong evidence either way. Ferrets need dental checkups regardless of diet, and some owners offer occasional raw meaty bones under vet guidance. Ask your vet to check your ferret’s teeth at each visit.
Can kits eat Epigen 90?
Check the current label for life stage guidance. Growing kits have high energy needs, so talk to your vet or breeder before choosing a food for a young ferret.
