Sustainable Seafood for Cats: A Greener Way to Feed Your Feline

When we think of sustainable living, we usually think of cutting out plastic or driving less — but what about our pets’ food? If you’ve got a cat who loves tuna, salmon, or seafood blends, there’s a good chance you’ve wondered: is all that fish really eco-friendly?

Here’s what you should know about sustainable seafood for cats — and how to make better choices for the planet without skipping your cat’s favorite meal.


🐟 The Problem with Conventional Seafood in Pet Food

Many popular cat foods use low-grade fish meal, tuna, or ocean-caught ingredients with very little transparency. The problem? Overfishing, bycatch (non-target marine life like turtles and dolphins), and high carbon shipping costs make traditional fish-based cat foods tough on the environment.

Some even contain species on the “at-risk” list, depending on where and how they’re caught.


✅ What Makes Seafood “Sustainable”?

Not all fish are bad for the environment. Sustainable seafood is:

  • Caught or farmed in a way that doesn’t damage ecosystems

  • Certified by groups like MSC (Marine Stewardship Council) or ASC (Aquaculture Stewardship Council)

  • Traceable — you should know what fish it is and where it came from

Brands that use small, fast-reproducing fish (like sardines or anchovies) or responsibly farmed seafood have a smaller environmental footprint than those using long-lived species like tuna or cod.


🐾 Choosing the Right Cat Food

If you’re aiming to lower your cat’s environmental pawprint, look for:

  • Clearly labeled ingredients (avoid mystery “fish” or “ocean meat”)

  • Certifications like MSC or Wild Caught Sustainable

  • Single-source proteins (fewer mixed fish scraps)

  • Ethical sourcing statements on brand websites

You’ll also want to check that the packaging is recyclable or made with post-consumer materials when possible.

We’ve broken down what to look for in this guide on sustainable cat feeding.


🧠 Can Cats Be Vegetarian?

No. Cats are obligate carnivores — they need nutrients like taurine, arachidonic acid, and vitamin A, all of which come from animal sources. That’s why plant-based cat food isn’t safe unless it’s heavily supplemented (and still controversial among vets).

Instead, the goal should be better sourcing, not removing meat entirely.


🌍 Don’t Forget Packaging

Even if you’ve found a sustainable brand, the packaging can still create waste. Go for:

  • Larger cans or pouches (less per-serving waste)

  • Recyclable metal or cardboard containers

  • Brands offering bulk or refill options if available locally

Bonus: fewer trips to the store or fewer deliveries can reduce your footprint too.


Final Thought

Feeding your cat responsibly isn’t about guilt — it’s about awareness. If you can swap out one fishy food brand for a more sustainable one, that’s a win for your cat and the ocean.
