6 Best Squirrel Food Blends for Nutrition
A healthy coat starts with diet. See the 6 best food blends wildlife rehabbers trust for optimal squirrel nutrition and a lush, glossy coat.
You can tell a lot about a squirrel’s health just by looking at its coat. A thick, glossy coat means good nutrition, while a patchy, dull one is often the first sign something is wrong. For wildlife rehabilitators, getting that nutrition right is a matter of life and death, so they don’t leave it to chance. The food blends they rely on are designed for optimal health, not just for filling a belly.

Key Nutrients for a Squirrel’s Healthy Coat
A healthy coat is built from the inside out. It’s a direct reflection of a squirrel’s internal health, and it all comes down to a few key nutrients. Without the right building blocks, you’ll see a dull, thin coat no matter what else you do.
The most critical element is the calcium-to-phosphorus ratio. Nuts and seeds, a squirrel’s favorite snack, are loaded with phosphorus but have very little calcium. An imbalance here leaches calcium from the bones, leading to Metabolic Bone Disease (MBD), a crippling and often fatal condition. A shiny coat means nothing if the skeleton can’t support it.
Beyond minerals, high-quality proteins are essential for building strong hair follicles. Healthy fats, especially omega-3 and -6 fatty acids, provide the oils that give fur its sheen and water resistance. Finally, vitamins like A, E, and especially D are crucial. Vitamin D is necessary for the body to even absorb calcium in the first place, making it a cornerstone of a healthy diet.
Henry’s Healthy Blocks: Rehabber’s Top Choice
When you talk to experienced rehabbers, one name comes up more than any other: Henry’s Healthy Blocks. This isn’t just a food; it’s a complete nutritional system designed specifically for squirrels and other rodents. Its entire formula is built around preventing MBD.
The magic of Henry’s is its formulation. It has the correct 2:1 calcium-to-phosphorus ratio baked right in, along with all the necessary vitamins, including Vitamin D3. Because it’s a uniform block, the squirrel can’t selectively feed—it gets balanced nutrition in every single bite. This is a game-changer compared to loose seed mixes where they just pick out the junk food.
Of course, quality comes at a price. Henry’s Blocks are more expensive than store-bought mixes and usually have to be ordered online and kept frozen. But for ensuring the absolute best health for a recovering or overwintering squirrel, most rehabbers agree it’s a non-negotiable investment.
Mazuri Rodent Diet for Consistent Nutrition
Mazuri is a workhorse in the world of animal nutrition. It’s trusted by zoos, vets, and research facilities for one simple reason: consistency. Every bag of Mazuri Rodent Diet delivers the exact same lab-tested, balanced nutrition.
This diet comes in a block or large pellet form, which is ideal. It forces the squirrel to gnaw, which is excellent for their ever-growing teeth, and completely prevents the picky eating that plagues seed mixes. You know they are consuming a complete diet, not just the fatty, high-phosphorus bits they prefer.
While it’s not formulated specifically for squirrels like Henry’s is, it provides a fantastic nutritional foundation. Many rehabbers use Mazuri as their daily base diet due to its reliability and accessibility. Think of it as the well-balanced, home-cooked meal that you can build upon with supplemental fresh foods.
Kaytee Forti-Diet Pro Health for Rodents
You’ll find Kaytee on the shelf of almost any feed or pet store, making it one of the most accessible options available. The Forti-Diet Pro Health line is a definite step up from basic wildlife mixes, as it’s fortified with key vitamins and minerals. It even contains probiotics to support digestive health.
However, this is where you have to be a smart consumer. Many of these mixes contain the good stuff—the fortified pellets—right alongside colorful, tasty-looking seeds, corn, and dried fruit. A squirrel will almost always eat the "treats" and leave the healthy pellets behind. This selective feeding completely undermines the "fortified" benefits.
If you choose a mix like this, your best bet is to find one that is primarily pellets, or be prepared to see a lot of the healthy components discarded. It can be a decent choice in a pinch, but you have to watch what the animal is actually eating, not just what’s in the bowl.
Oxbow Essentials Rat Food for Balanced Diets
Don’t let the name fool you. Oxbow Essentials Rat Food is an excellent choice for squirrels, and many rehabbers swear by it. Oxbow has a stellar reputation for high-quality ingredients and science-backed formulas, and this product is no exception.
The key benefit here is the uniform kibble. Every piece is identical, containing a balanced mix of protein, fat, and fiber, plus essential vitamins and minerals. There is zero opportunity for selective feeding. It’s a clean, simple, and effective way to deliver a complete diet without the sugary additives and artificial colors common in lower-end foods.
This is a great alternative if you can’t find Mazuri or want to avoid the fillers present in some other brands. It provides a stable, healthy base diet that ensures your squirrels are getting the core nutrition they need for strong bones and a healthy, vibrant coat.
Wild Delight Squirrel Food: A Fortified Nut Mix
This is the kind of food people love to buy. It’s full of whole peanuts, sunflower seeds, and corn, and squirrels go absolutely wild for it. It’s marketed as a premium mix, often "fortified" with vitamins, which sounds great on the bag.
Here’s the hard truth: this should be considered a treat, not a primary food source. The core ingredients are incredibly high in phosphorus and fat, and dangerously low in calcium. Over-reliance on this type of food is a leading cause of MBD in backyard squirrels. They fill up on this junk food and then have no appetite for the nutrient-dense foods they need.
Think of it like candy. A little bit as a rare treat is fine and fun to watch. But making it a daily staple is nutritionally devastating. If you use this, offer only a tiny amount after you know they’ve eaten their primary, block-based food.
Zupreem Primate Diet: An Unconventional Pick
Here’s a tip straight from the deep knowledge base of seasoned rehabbers: Zupreem Primate Diet. It sounds odd, but when you look at the nutritional profile, it makes perfect sense for squirrels, especially those needing to gain weight or with special needs.
Primate diets are formulated to be highly palatable and nutritionally complete for complex animals. They contain a balanced mineral profile and, critically, Vitamin D3, which squirrels need to process calcium. The biscuit or chunk form is great for dental health and, once again, prevents selective feeding.
This isn’t your everyday feeder food for a wild population. It’s a specialized tool, often used for non-releasable animals or those in long-term care who need a boost. It’s a perfect example of how rehabbers look at the nutritional science, not just the animal on the label.
Crafting a Balanced DIY Squirrel Food Blend
While a formulated block should be the cornerstone of any squirrel’s diet, variety is key for both health and enrichment. Crafting your own supplemental blend is a great way to round out their nutrition, but you have to do it right. The goal is to supplement the base diet, not replace it.
A good rule of thumb for a daily offering follows an 80/15/5 structure:
- 80% High-Quality Rodent Block: This is the non-negotiable foundation. Henry’s, Mazuri, or Oxbow should make up the vast majority of their intake.
- 15% Healthy Vegetables: Offer a rotating variety of fresh, squirrel-safe veggies. Good choices include broccoli, kale, sweet potato, zucchini, and snap peas.
- 5% Nuts, Fruits, or Seeds: This is the treat category. We’re talking about one or two high-quality nuts (like an acorn, hazelnut, or pecan) or a small slice of fruit per day. This portion must be kept small.
This approach ensures they get their core nutrition from the blocks first. The fresh veggies provide hydration and micronutrients, and the "treats" offer enrichment without wrecking their calcium balance. This is how you build a truly healthy diet that supports everything from bone density to that beautiful, glossy coat.
Ultimately, supporting wildlife responsibly means understanding their needs, not just their wants. A squirrel will always choose a peanut over a nutrient block, but a healthy coat and strong bones are built on the latter. By making a high-quality, block-based food the foundation of their diet, you’re providing the best support possible, whether it’s for an animal in your care or just a frequent visitor to your backyard.
