Instinct Original coats each kibble piece with freeze-dried raw chicken, adding enzymes and probiotics that high-heat extrusion destroys. It's the best bridge between dry food and raw for cat owners.

The full review

Cats Are Obligate Carnivores

Unlike dogs (omnivores), cats can't produce taurine or convert beta-carotene. They require animal-sourced nutrition. Instinct's 81% animal ingredients align with feline nutritional biology better than most mainstream cat foods, which use significant plant-based carbohydrates.

Raw Coating Benefits

Freeze-drying preserves enzymes that support digestion and immune function. The coating also dramatically improves palatability — cats consistently prefer raw-coated kibble in palatability trials over standard dry food.

Common questions

Is freeze-dried raw safe for cats?
Yes — freeze-drying eliminates pathogens while preserving nutrients. Instinct sources from USDA-inspected facilities.
How should I transition my cat?
Mix 25% Instinct with 75% current food for week 1. Increase gradually over 2 weeks. Cats switching from cheap dry food may initially resist the change in smell.
