FAQ
Why does protein matter more for cats? Cats are obligate carnivores with higher protein requirements than dogs. The AAFCO minimum for cats is 26% on dry matter basis; Pro Plan’s 40% better reflects feline nutritional needs.
Has Blue Buffalo cat food been recalled? Blue Buffalo cat food was part of the 2019 recall for elevated vitamin D levels. No recalls since.
Is Blue Buffalo Wilderness good for cats? Wilderness grain-free offers higher protein (40%) than Blue Buffalo Indoor. It’s a strong option for cats needing high-protein grain-free.
Which is better for an indoor cat? Both have indoor formulas. Pro Plan’s higher protein and live probiotics make it superior for maintaining lean mass in less active indoor cats.
