Sustainable Protein Sources for Pets: Insects, Fish, or Poultry?

Pet food is changing fast, and more brands are highlighting “sustainable protein” on their labels. But what does that really mean when you’re choosing what goes in your pet’s bowl? Let’s look at three popular options—insects, fish, and poultry—and how to pick what’s best for your pet and the planet.

Insect Protein: Small Creatures, Big Impact

Insects are one of the rising stars in eco-friendly pet food.

• Often raised using less land, water, and feed than traditional livestock.

• Can be grown on food scraps, helping reduce waste.

• Naturally rich in protein, healthy fats, and minerals.

Easy tip: If your pet is new to insect protein, start with treats or a mixed formula (insect plus another protein) and watch for any signs of sensitivity.

Fish: Omega-3s with a Catch

Fish can be both nutritious and more sustainable than red meat—if it’s sourced carefully.

• Great source of lean protein and omega-3 fatty acids that support skin, coat, and joints.

• Often easier to digest for some pets with sensitivities.

• Sustainability depends heavily on fishing practices and fish species.

Easy tip: Look for wording like “wild-caught” and third-party sustainability logos on the bag, and avoid vague labels like “fish meal” with no detail on the species.

Poultry: The Familiar, Lower-Impact Meat

Compared to beef or lamb, poultry usually has a smaller environmental footprint.

• Chicken and turkey are widely available, affordable, and familiar to most pets.

• Often used in formulas designed for everyday, balanced nutrition.

• Impact varies by how birds are raised and how much waste a brand creates.

Easy tip: Choose brands that mention “responsibly sourced,” “free-range,” or “certified humane” when possible, and buy bag sizes your pet can finish while fresh to avoid waste.

How to Choose: Simple Checklist

You don’t have to be an expert to make a better choice. Ask yourself:

• Does this food list a clear, named protein (like “black soldier fly larvae,” “salmon,” or “turkey”) instead of just “meat”?

• Does the packaging mention sustainability or ethical sourcing in a specific, not vague, way?

• Is it labeled “complete and balanced” for my pet’s age and size?

• Does my pet actually feel and look good on it (energy, coat, digestion)?

One Small Change at a Time

You don’t need to overhaul everything overnight. Try:

• Swapping one meal a week to a more sustainable protein.

• Testing an insect- or fish-based treat before committing to a full bag.

• Sticking with what your pet’s stomach loves, but upgrading to a more responsible brand or protein.

Sustainable pet food should still be simple: something your pet thrives on, that fits your budget, and that feels better for the planet. Start with one small swap and build from there.
