Veterinary Diets EN Gastroenteric Naturals Feline Formula Dry Cat Food
Verified Jun 8, 2026
This is a high-protein veterinary dry cat food designed for kittens and adult cats that need gastrointestinal support. It uses chicken meal, soy protein, egg, and rice as key protein and energy sources, with added prebiotic fiber and pumpkin to help support digestive health. The formula is complete and balanced for growth and adult maintenance and is made without corn, wheat, or artificial colors or flavors.
Nutritionally, this is a thoughtfully formulated gastrointestinal diet with very high protein and moderate fat, appropriate for cats that need easily digestible nutrition. The combination of animal and plant proteins, rice, and egg helps support digestion while keeping the fiber level fairly low, which many cats with GI issues tolerate well. It is complete and balanced for both kittens and adults, but because it is a prescription formula, it’s best used specifically for cats with digestive concerns under a vet’s direction.

At a Glance
KibbleLab Review
Strengths
- Very high protein at 46% from chicken meal, soy, egg, and pea protein supports cat’s natural protein needs.
- Moderate fat level at 16% with added fish oil provides energy and beneficial omega-3 fatty acids.
- Formulated to AAFCO standards for both kitten growth and adult maintenance, so it can be used long term if needed.
- Includes pumpkin, prebiotic yeast ingredients, and controlled fiber to help support digestive health.
Considerations
- Contains multiple common allergens, including chicken, egg, soy, and dairy components, so it is not ideal for cats with food allergies.
- High protein and calorie density mean portions must be measured carefully for cats prone to weight gain.
- Uses a mix of animal and plant proteins, which some very sensitive cats may tolerate differently than single‑protein diets.
- This is a specialized veterinary diet, so it should be fed under guidance from your veterinarian.

Top 5 Ingredients Explained
01
Chicken
Chicken is a common animal-based protein in dog and cat foods, supplying essential amino acids, B vitamins, and energy-dense fats that support muscle maintenance, growth, and overall health; for cats it also contributes toward dietary taurine but must be present in sufficient amounts or provided via supplementation. It is prized for its digestibility and palatability, though some pets develop sensitivities or allergies to chicken, and nutritional value and safety depend on ingredient quality and processing—raw chicken carries pathogen risks and whole bones can pose choking or GI hazards.
02
Soy Protein
Soy protein is a concentrated plant-based protein commonly used in pet foods to boost protein content, improve texture and binding, and provide a cost-effective alternative to animal proteins. It supplies substantial protein for dogs and can be used in cat diets when formulas are properly balanced, but its amino-acid profile and digestibility are generally lower than animal proteins (often requiring supplementation such as taurine for cats), and some pets may have soy sensitivities or be affected by soy compounds, so diets with soy should be formulated and processed appropriately.
03
Brewer's Rice
Brewer’s rice is a milling byproduct of rice processing made up of small broken white rice kernels commonly used in pet foods as a highly digestible carbohydrate source, filler and binder that provides readily available energy for dogs and cats while contributing little protein, fat or fiber. It is generally gentle on the stomach and cost‑effective, but diets using it must supply other ingredients for essential nutrients; pet owners should note its relatively high glycemic load (relevant for weight or diabetic pets), the potential for trace environmental contaminants associated with rice, and not confuse it with brewer’s yeast.
04
Egg Product
Egg product is used in pet foods as a high-quality, highly digestible animal protein and palatability enhancer, providing complete essential amino acids, fats, vitamins (such as A, D and B12), minerals and choline, and it often serves as a binder or emulsifier when included as whole, dried or concentrated egg. It supplies bioavailable nutrients for dogs and cats but can be a food allergen for some individuals, may be higher in fat depending on yolk content, and should be properly processed (pasteurized or cooked) to reduce microbial risk.
05
Animal Fat
Animal fat is used in pet foods as a concentrated energy source and palatability enhancer, and can provide fat-soluble vitamin absorption and essential fatty acids (including arachidonic and linoleic acids, depending on the source) that support skin, coat and overall cellular function—particularly important for obligate carnivores like cats. Because it is calorie-dense and prone to oxidation, fats are typically rendered and stabilized; owners should be aware that high-fat diets can contribute to obesity and may trigger pancreatitis in susceptible dogs, so quality, source, and total dietary fat should be considered.
