If you're a cat owner in the Greater Toronto Area weighing your options between Nulo's two main product lines, you're in the right place. Nulo builds its reputation on high protein content and low-carbohydrate recipes, but the Freestyle and MedalSeries lines aren't identical. This guide breaks down the real differences so you can pick the right bag for your cat. Ready to shop now? Browse our full cat food collection or jump straight to dry cat food.

Our team at Ashario Pets fields this exact question weekly — especially from customers in the Yonge-Finch area feeding indoor cats who need lean, protein-forward nutrition. Below, we lay out the formulas, the guaranteed analysis numbers, and who each line suits best. For an even deeper dive, see our companion article: Nulo Cat Food Review 2026: Freestyle and MedalSeries Formulas Compared for Canadian Cats.

Key Takeaway: Nulo Freestyle is the brand's premium, higher-protein, lower-carb line (often 80%+ animal-based protein), while MedalSeries is a value-oriented line with slightly higher plant content and added functional ingredients. Both meet AAFCO nutrient profiles — Freestyle suits weight-conscious and grain-sensitive cats, MedalSeries suits budget-minded owners wanting solid everyday nutrition.

What is the difference between Nulo Freestyle and MedalSeries?

The core difference is protein density and ingredient tier. Nulo Freestyle typically delivers 40–45% protein content in dry recipes with animal proteins as the top ingredients, keeping carbohydrates low. MedalSeries usually runs around 34–38% protein content and includes a broader mix of ingredients, making it a friendlier price tier while still exceeding AAFCO minimums.

Both lines are grain-free by default and use Nulo's signature low-glycemic approach. According to AAFCO, adult cats require a minimum of 26% protein and 9% fat on a dry-matter basis for maintenance — both Nulo lines clear that bar comfortably. Where they diverge is in the source and concentration of that protein.

Freestyle leans heavily on deboned chicken, turkey, cod, salmon, and duck, with fewer secondary carbohydrate binders. MedalSeries incorporates functional add-ins and a slightly wider ingredient panel, which is why our nutrition experts at the North York store often recommend it as an accessible entry point for owners transitioning off supermarket kibble.

Protein and fat content at a glance

• Nulo Freestyle dry cat food — roughly 42% protein content, 18% fat content, with animal protein making up around 80% of total protein.
• Nulo MedalSeries dry cat food — roughly 36% protein content, 16% fat content, with a slightly higher proportion of plant-derived nutrients.
• Both include taurine for heart and eye health (essential for cats, which cannot synthesize enough on their own).
• Both feature added probiotics for digestive support and omega-3 and omega-6 fatty acids for skin and coat.

Pet owners tell us their cats' coats look noticeably glossier within a few weeks on either line — a benefit tied to those omega-3 and omega-6 levels. As always, we recommend confirming any dietary change with your veterinarian, especially for cats with existing health conditions.

Which Nulo formula is best for high-protein feeding?

For owners specifically seeking the highest-protein option, Nulo Freestyle is the clear winner. Its dry recipes reach around 42% protein content with roughly 80% sourced from animal ingredients, making it one of the more concentrated high protein dry cat food options available in Canada. MedalSeries is still protein-rich but sits a notch lower.

High-protein, low-carb diets align with a cat's biology as an obligate carnivore. The American Veterinary Medical Association notes that cats have a high dietary protein requirement compared to dogs, and reduced-carbohydrate feeding may support healthy weight in indoor cats. When a customer comes in asking about a chunky indoor tabby, we typically point them to Freestyle first because of that lean profile.

Nulo Freestyle vs MedalSeries: full comparison

Bottom Line: Choose Freestyle for the leanest, most protein-dense feeding. Choose MedalSeries when you want a quality grain-free diet at a gentler price point. Both are appropriate for adult maintenance under AAFCO standards.

Is Nulo cat food good for Canadian cats specifically?

Yes — Nulo cat food is a strong option for Canadian cats, particularly indoor cats who account for the majority of pets in urban centres like Toronto. Indoor cats burn fewer calories, so a high-protein, low-carb formula helps them maintain lean body condition rather than packing on weight from carbohydrate-heavy kibble.

Indoor cats in condos and apartments across North York and downtown Toronto move less than farm or outdoor cats. That makes calorie management important. A typical adult cat needs roughly 20 kcal per pound of body weight per day, so a 10 lb cat needs around 200 kcal daily. Nulo's dense formulas mean you feed a modest portion — often 1/3 to 1/2 cup per day — which keeps portion control simple.

Our team at Ashario Pets stocks a wide range of premium cat nutrition beyond Nulo, so if your cat doesn't take to it, we can help you transition. Explore our full cat food selection or browse wet cat food to add moisture to a dry-food routine.

How to transition your cat to Nulo safely

Cats are notoriously sensitive to abrupt diet changes. Transition gradually over 7 to 10 days: start with 25% new food mixed with 75% old for days 1–3, shift to 50/50 for days 4–6, then 75% new for days 7–9, and finally 100% new. The ASPCA and most veterinary nutritionists endorse this slow approach to avoid digestive upset. If your cat vomits, refuses food, or has loose stool, slow the pace and consult your veterinarian.

Adding a splash of warm water or a spoonful of wet food can boost palatability during the switch. Our nutrition experts at the North York store often suggest pairing dry Nulo with a complementary wet topper for hydration, since cats have a naturally low thirst drive.

Freeze-dried and wet options: rounding out a Nulo diet

Beyond dry kibble, a complete feeding plan can include freeze-dried food and wet food for moisture and variety. Cats derive most of their hydration from food, and a diet that's exclusively dry may leave some cats under-hydrated, which matters for urinary health.

If you want to layer textures, consider adding a freeze-dried cat food topper or rotating in wet cat food. We carry a broad lineup of grain-free wet and freeze-dried options at our store. Customers love mixing a high-protein dry base with a wet meal at dinnertime — it keeps finicky eaters interested while boosting daily moisture intake.

Final verdict: which Nulo line should you buy?

As of 2026, both Nulo Freestyle and MedalSeries are solid grain-free choices, and the right pick comes down to your cat and your budget. Freestyle is the premium, protein-dense line for lean-body maintenance and grain-sensitive cats. MedalSeries delivers quality nutrition at a more accessible price with helpful functional ingredients.

We tested feeding notes from customers on both lines and found palatability high across the board, with coat and stool quality reported as excellent on Freestyle in particular. Whichever you choose, transition slowly, watch body condition, and lean on your veterinarian for any health-specific guidance.

Frequently Asked Questions

Is Nulo Freestyle worth the higher price over MedalSeries?

For most weight-conscious, indoor, or grain-sensitive cats, yes. Freestyle offers around 42% protein content with roughly 80% animal-based protein and a very low carbohydrate level, making it ideal for lean-body maintenance. MedalSeries at around 36% protein is still an excellent value choice — the "worth it" answer depends on your cat's needs and your budget.

Does Nulo cat food meet AAFCO standards?

Yes. Both Nulo Freestyle and MedalSeries are formulated to meet the nutrient profiles established by AAFCO for their stated life stages. Adult cats need a minimum of 26% protein and 9% fat on a dry-matter basis; both Nulo lines exceed those minimums comfortably. Always check the guaranteed analysis on the specific bag you buy.

Is Nulo cat food available in Canada at Ashario Pets?

Ashario Pets is a premium pet supply store at 1111A Finch Ave W, Unit 2, North York, Ontario, open 7 AM to 11 PM daily, 365 days a year. We carry premium dry and wet cat food and can help GTA cat owners find high-protein grain-free options in store or via Uber Eats, DoorDash, SkipTheDishes, Instacart, and Fantuan delivery.

How much Nulo dry food should I feed my cat per day?

A typical 10 lb adult cat needs roughly 200 kcal per day, which usually translates to about 1/3 to 1/2 cup of dense Nulo dry food, split into two meals. Because both lines are calorie-rich and protein-dense, you often feed less than with carbohydrate-heavy kibble. Adjust based on activity, age, and body condition, and follow the feeding chart on the bag.

Can I mix Nulo Freestyle and MedalSeries together?

You can, as long as you introduce both gradually and monitor your cat's stool and body condition. Since both are grain-free and nutritionally complete for adult maintenance, blending them is generally fine. Many owners rotate proteins to keep picky eaters interested. If your cat has a medical condition, check with your veterinarian first.
