The Power of Krill for Dogs & Cats

Home / Blog | Read Time: 6 minutes

Krill are tiny crustaceans, only about 2 inches long. But don’t be fooled by their small size — they can change your pet’s life.

Though they are teensy ocean creatures, krill are packed with vital nutrition that can help our land-dwelling cats and dogs live a long, vibrant life. No matter the age, size, or breed of your pet, krill can provide them with crucial nutrients that nourish and fuel the entire body. And that means more time and energy for all their favorite things — from curtain-climbing to frisbee fetch.

There’s a reason krill should be on your radar — and in your pet’s bowl. Actually, a LOT of reasons. So let’s dive in…

The Power of A Single Ingredient

Krill is packed to the brim with nutrition — and yet, it’s just one ingredient. One ingredient means no preservatives, no artificial additives, and no fortifying. It’s just plain krill — high-quality nutrition straight from the ocean. All the good stuff and none of the bad.

So what exactly is all that good stuff? What makes krill so vital for our cats and dogs?

1. Omega 3

Krill is full of omega-3 fatty acids. We’re talking good fat. Omega 3s promote a healthy inflammatory response throughout your pet’s entire body and benefit everything from the heart to the immune system.

Cats and dogs can’t produce omega 3 on their own, so they absolutely need to be eating omega-rich foods. Not only that, but it has to be the right kind of omega 3s — with DHA and EPA fatty acids. This form is readily available for the carnivore’s body to use — a.k.a. exactly what ferocious Mr. Fluffums needs. And that’s exactly the kind you will find in krill.

Plant-based sources of omega 3, on the other hand, contain ALA, which isn’t as bioavailable to your pet — and therefore not as beneficial. So be on the lookout for meat based sources of omega 3, which contain that vital DHA and EPA.

Omega 3 with EPA and DHA

Omega 3 with ALA

One last thing: adding omega 3 to the bowl is especially vital for kibble-fed pets. Kibble usually provides a lot of omega 6 and hardly any omega 3 — and it’s all about a balanced ratio with these two omegas. Too much omega 6 and not enough omega 3 can lead to inflammation and health problems. So don’t hold back when you add omega 3 to the bowl!

2. Phospholipids

Phospholipids deliver the omega 3 right to where your pet’s body needs it most and help the body absorb a greater amount. This makes krill a super efficient and high-quality source of omega 3s. Nutrients aren’t useful unless the body can actually use them, and phospholipids make it possible for the body to maximize the omega 3s and really reap the benefits.

3. Choline

Krill also contains choline, an essential nutrient shown to promote brain, heart, and liver health. Not bad. Not bad at all.

4. Astaxanthin

Astaxanthin is known as “nature’s most powerful antioxidant.” It’s hundreds of times more powerful than other antioxidants, which means its free-radical scavenging ability is unparalleled.

Antioxidants neutralize free-radicals in the body, which prevents oxidative stress (cell damage) and premature aging. Filling the bowl with antioxidant-rich foods gives your pet the tools their body needs to stay healthy and strong — especially as they age.

And here’s a hot tip for kitty parents — cats especially need meat sources of antioxidants (like astaxanthin!) because cats aren’t meant to have loads of leafy greens. Dogs can thrive with a combination of plant-based and meat-based antioxidants (yes, you should give your dog spinach!), but cats are obligate carnivores, which means meat is the name of the game pretty much 24/7. This makes krill absolutely crucial to a kitty’s diet — it’s a meat protein and nature’s most potent antioxidant all in one. And that’s win/win.

The Power of Sustainable Choices

There’s another piece to consider when you decide to fill your pet’s bowl with krill: we want healthy pets, but we also want a healthy planet — which means paying attention to our marine ecosystems and making sustainable choices.

Always look for manufacturers that source from fisheries that are committed to sustainability and minimizing our environmental impact (look for the Marine Stewardship Council label).

In our Simple Food Project recipes, we only use wild-caught krill. Our MSC-certified supplier is one of the most sustainable fisheries worldwide, with a deep commitment to conservation. They created a revolutionary technology called Eco-harvesting, which utilizes a hose to collect krill and bring it on board. This ensures that no other marine wildlife is harmed in the process. This kind of technology and conscientiousness allows us to care for our pets and our planet simultaneously.

As you peruse your krill options, you may come across chews and oils, but our recommendation is ground krill — which is the entire krill.

Ground krill is by far the most sustainable option. In order to produce oils and chews, manufacturers extract oil from the krill — and then throw away what remains. This is especially true for how humans use krill (since humans typically don’t want to eat a whole krill). If the rest of the krill isn’t used for anything, this practice is wasteful.

That’s where ground krill comes in. Ground krill uses the entire krill — including the parts that would otherwise be discarded after oil extraction. So when you choose ground krill, you’re also choosing an option that complements the human industry, provides your pet with maximum nutrition and honors the krill and marine ecosystem.

The Power of Krill

Preventive care is incredibly powerful, and adding krill to the bowl is one of the best things you can do for your pet’s long-term health. Krill provides the body with vital nutrition during every phase of life — from developing puppy brains to aging seniors.

Krill can:

Boost the immune system
Encourage a healthy inflammatory response
Defend against free radical cell damage
Promote healthy aging
Support growth and development
Foster heart health
Balance the Omega 6 : Omega 3 ratio
Elevate a kibble diet
Support overall health and wellbeing

No matter the size, age, or breed of your pet, the nutrients in krill provide every pet with the tools to thrive. Krill can take every single pet’s health and wellbeing to the next level.

That’s why Dr. Bessent added ground krill into every one of our Simple Food Project Recipes. And if your pet needs a little extra, it’s as easy as adding ground krill like Pure Krill to the bowl. Just be ready for your pet to go crazy for that fishy flavor.

Regardless of how you feed krill, you’ll be taking a concrete step toward a healthier pet. The krill will nourish the entire body, allowing your favorite four-legger to start reaping the health benefits.

6 Ingredients in Cat “Food” That Aren’t Meant To Be Eaten

Home / Blog | Read Time: 6 minutes

Mr. McWhiskers is a pure delight. He only scratches the sofa sometimes (he’s very polite that way), he’s an excellent coworker and sits on your laptop right on time every day, and he takes all your outfits to the next level with the refined layer of hair he leaves behind.

Mr. McWhiskers deserves the best in every way — especially in terms of what he eats (because let’s be honest, Mr. McWhiskers LOVES to eat).

But is he eating ingredients that aren’t meant to be eaten?

We’re not talking about the occasional pillow stuffing that just somehow escaped from the pillow. Or a thread from that sock he stole.

No. We’re talking about ingredients within his cat food. Ingredients that manufacturers put in his food intentionally. Ingredients that you would never dream of eating.

You know that long list of ingredients on the back of the cat food bag? Yep. That’s where you’ll find these doozy ingredients. And the actual uses of these ingredients (i.e. their proper, non-food uses) should raise some red flags. Like — giant, wildly-flapping-in-the-wind, neon red flags.

The Problem(s) With Kibble

Many pet parents choose to feed kibble. True, it’s a convenient choice — but convenience comes with some scary tradeoffs.

Kibble is heavily processed and often has a shelf life of decades. It’s akin to junk food. Yes, it’s cheap and convenient, but it often causes obesity and numerous health problems down the road. Plus, it doesn’t properly nourish the body — even though it can cause obesity. Kibble leads to overfed and undernourished pets.

It’s also worth noting how kibble is made. In production, the kibble is heated to extremely high temperatures — 275-572 degrees F. The idea is that this temperature will kill pathogens (which it does), but it also ends up killing healthy components like antioxidants and enzymes. Additionally, when proteins and carbohydrates are heated to such high temperatures, they become toxic and/or carcinogenic (read: cancer-causing).

This is serious stuff. Our four-leggers deserve better.

Many Cat “Foods” Contain Ingredients That Are Not FOOD

Okay, so we know some concerning things about kibble. Now let’s get to the nitty-gritty — the specific ingredients that should make you run.

Let’s demystify some of the ickiest and most dangerous ingredients for your cat. We’ll cover 1) what the ingredients are and 2) what they are supposed to be used for (hint: not food).

Powdered Cellulose

What is it: Cellulose is a fibrous plant-based compound. It comes from plants, which doesn’t sound too alarming, but don’t be fooled. This is not meant to be eaten by cats — or anyone, for that matter.

What is it supposed to be used for: Cellulose is typically used to make paper and fabrics. It’s also used in household items like sponges and glue. The form often found in cat food is derived from sawdust, which is considered a “byproduct” or “waste” from wood. Sawdust is great for various landscaping uses and to soak up spills, but it is certainly not meant for Mr. McWhiskers to have for dinner.

Food Dyes (Yellow 5, Yellow 6, Red 40, Blue 2)

What is it: Food dyes are artificial chemicals that can provide color to many foods (ever had a lollipop that left your tongue blue for hours?).

What is it supposed to be used for: Well, coloring food at best. But we have to ask if this is really necessary — especially for CATS! Does your cat really care or even see what color her food is? Colors are often added to make the food look more enticing to you (the consumer, not your cat). But artificial colors just aren’t worth the cancer risk. Yep, food dyes are known carcinogens for animals. No, thank you. It’s just not worth it.

Ethoxyquin

What is it: Ethoxyquin is a synthetic preservative meant to prevent rancidity.

What is it supposed to be used for: Certainly not food! Ethoxyquin is banned for direct use in human food (it’s toxic if it touches the skin or is swallowed), but it is allowed in pet food — that should be a red flag right there. And the scientific community has some pretty big concerns relating to toxicity that can lead to autoimmune disorders, reproductive damage, cancer, and more.

BHT and BHA

What is it: These are closely related synthetic chemical preservatives (often in dry cat food and human food like cereal and packaged snacks).

What is it supposed to be used for: In addition to being used as food additives, BHT and BHA are commonly used in beauty products, plastic, gasoline, wax, paint, and more (ew). What’s even worse? They’re known carcinogens.

Meat and Bone Meals

What is it: Meat and bone meals are a mysterious mixture from sources such as roadkill, expired food from grocery stores, and inedible byproducts from slaughterhouses. These meals often contain bones and feathers and very little (if any) valuable parts like muscle meat, which is reserved for human consumption. The meal is formed through a high temperature and high-pressure process that essentially converts carcasses and byproducts into a powdery substance — and that is what goes into your pet’s food (yikes).

What is it supposed to be used for: Well, compost at best. Meat and bone meals are often essentially garbage that’s being repurposed as food for our pets. We’re all about repurposing, recycling, and sustainability, but here’s something we’re not about: feeding our pets unhealthy and unsafe waste.

Glucose and Grains (Wheat, Corn, Rice)

What is it: Here are some familiar and recognizable ingredients (finally)! We’re going to assume you know what grains are. And as a Biology 101 reminder, glucose is a simple sugar and a component of carbohydrates.

What is it supposed to be used for: This category is a little different. For other species (like humans or goats), grains are perfectly appropriate. The issue is that the grain is not species-appropriate for cats. Have you ever felt like your kitty is hungry all the time? Well, that’s because she’s not getting the nutrition she really needs. Cats simply cannot process high-carbohydrate ingredients like grains and fillers. A high-meat diet is absolutely imperative to their survival. So even if your kitty eats a seemingly appropriate amount of food each day, she still won’t get the nutrition she needs if that food is filled with carbohydrates. (You can learn more with “Cats and Kibble”).

What Cats Need to Thrive

Cats are obligate carnivores, which means their entire body is designed for hunting and consuming prey — meat. Anything other than meat in their diet should be limited, and carbohydrates (from produce and seeds) must be predigested. (Learn more with “Cat: The True Carnivore”). When you’re choosing a food for your cat, always look for high meat content (like 80-90%) and ingredients you recognize

Your cat deserves real, whole food — not “cat food” that isn’t actually food at all. We know that health starts with what’s in the bowl, so fill it with everything your cat needs to truly thrive!

Meat. Your cat would like us to emphasize once again that the answer is meat — and just to be clear, we’re talking raw meats and not meat meals (shudder).

And don’t forget about antioxidants and omegas, which support a healthy inflammatory response, boost heart health, foster a robust immune system, and promote healthy aging. Adding these doesn’t have to be complicated. In fact, single ingredients like krill can provide a supercharged daily dose of both these nutrients.

You can even learn to curate the bowl for your cat, filling it with the quality staples that all cats need and going beyond the basics to tailor a plan for your unique four-legger.

There are a lot of ways for you to give Mr. McWhiskers the nutrition he needs to thrive. The solution isn’t one-size-fits-all. Maybe you want to try DIY raw. Or maybe that’s a bit too much of an endeavor. In that case, another great option would be freeze-dried whole food nutrition like The Simple Food Project recipes.

Regardless, it’s safe to say several ingredients absolutely do not belong in your cat’s bowl. Now that you know what they are — and the non-food purposes they actually serve — you can make healthier choices for Mr. McWhiskers for years to come.
