Blue Buffalo BLUE Natural Veterinary Diet – GI Gastrointestinal Support is a dry adult formula developed to promote digestive comfort and regularity in cats.

The first ingredient is deboned chicken, supplying animal-based protein as the primary building block for lean muscle maintenance.

Additional concentrated poultry proteins (chicken meal and turkey meal) plus dried egg product boost amino acid density and digestibility, which matters when digestive efficiency may be compromised.

The recipe lists 36% crude protein and 14% fat, providing ample protein with moderate fat to meet adult maintenance needs.

Carbohydrates are listed at 28 and come from ingredients like tapioca starch and peas, offering readily digestible energy along with some fiber.

A fiber-focused approach is evident with 5% crude fiber and at least 1.0% soluble fiber, supported by pea fiber and flaxseed to help form consistent stools and support gut motility.

Omega-6 and omega-3 fatty acids are provided at 2.5 and 0.5 respectively, with chicken fat and flaxseed as sources that aid skin and coat health while contributing to a balanced inflammatory response.

Antioxidant support includes vitamin E at a minimum 300 IU/kg and ascorbic acid at 100 mg/kg, while mixed tocopherols also act as natural preservatives for fats.

Taurine at a minimum 0.2% supports normal heart function and vision, and the listed metabolizable energy (3622) offers a clear reference point for planning portions and monitoring weight trends.

Pros:

• Animal-first protein profile: Deboned chicken leads the ingredient list, providing highly digestible, species-appropriate protein for muscle maintenance.

• High overall protein: At 36% crude protein with chicken meal, turkey meal, and dried egg product, the formula delivers robust amino acid support.

• Targeted fiber support: 5% crude fiber with at least 1.0% soluble fiber, plus pea fiber and flaxseed, helps promote stool quality and regular bowel movements.

• Beneficial fatty acids: Omega-6 (2.5) and omega-3 (0.5) from chicken fat and flaxseed support skin barrier function and coat sheen.

• Antioxidant fortification: Vitamin E (300 IU/kg min) and ascorbic acid (100 mg/kg min) help neutralize oxidative stress while mixed tocopherols protect fats from oxidation.

• Essential taurine: A minimum 0.2% taurine supports cardiac function and retinal health in adult cats.

Cons:

• Legume and plant-protein inclusion: Peas and pea protein increase the share of plant-derived protein, which may not align with owners seeking exclusively animal-based protein sources.

• Refined carbohydrate source: Tapioca starch provides digestible energy but contributes limited micronutrients and may not suit very low-carb feeding preferences.

• Lower omega-3 relative to omega-6: Omega-3 (0.5) is notably lower than omega-6 (2.5), which could offer less anti-inflammatory support than diets with higher omega-3 inclusion.

• Dry format moisture: At 10% moisture, this kibble relies on adequate water intake or wet food pairing to support hydration and urinary health.

• Multiple animal proteins: Chicken, turkey, and egg may complicate elimination trials for cats needing single-protein diets.

• No probiotics listed: The provided information does not include live probiotic cultures, so microbiome support appears to rely on fiber rather than direct beneficial bacteria.
