In the millions of years of feline evolution, the ancestors of the modern house cat (Felis catus) were desert dwellers who obtained the vast majority of their moisture from the bodies of their prey. This biological history has created a unique physiological trait: cats have an incredibly low thirst drive. In the wild, a mouse is about 70-80% water—enough to hydrate a small predator. However, the shift to modern indoor living and the dominance of dry kibble (containing only 6-10% moisture) has inadvertently pushed millions of cats into a state of chronic, low-level dehydration.
The consequence of this imbalance is an alarming rise in chronic issues: kidney disease (CKD), idiopathic cystitis, and urinary crystals. Amidst this landscape, Bone Broth has emerged not just as a culinary trend “humanized” for pets, but as a promising functional nutrition solution.
Far more than just flavored water, bone broth is often dubbed “liquid gold” in pet nutrition circles. It is the result of a slow thermal hydrolysis process that extracts collagen, gelatin, essential amino acids, and trace minerals from animal bones into a highly bioavailable liquid. However, the market is exploding with hundreds of brands, from supermarket shelf staples to artisanal frozen pouches. This variety comes with risks: not all broths are safe. Hidden ingredients like garlic, onions, or high sodium levels can turn a nutritious bowl into a toxic hazard for a cat’s sensitive system.
This report is the result of synthesizing extensive data, including veterinary literature, ingredient analysis, and thousands of real-world experiences from cat owners and feline communities. Our goal is to provide a thorough, scientific, and objective look at the top 10 Cat Bone Broth products, helping you navigate the marketing maze to find the optimal solution for your four-legged friend.

The Science: Why Do Cats Need Bone Broth?
To properly evaluate these products, we must understand their mechanism of action at the cellular and physiological levels.
1. The Collagen and Gelatin Matrix: Architects of Connective Tissue
The core component that gives bone broth its value is Collagen. When bones, cartilage, and skin are simmered in a slightly acidic environment (often with apple cider vinegar) for extended periods (12-48 hours), the triple-helix structure of collagen breaks down to form Gelatin.
Gelatin contains a unique amino acid profile, particularly rich in Glycine, Proline, and Arginine.
- Glycine and Gut Health: Glycine has been shown to protect intestinal cells against oxidative stress. For cats with “leaky gut” issues or Irritable Bowel Disease (IBD), gelatin acts as a biological coating. It helps soothe inflammation and strengthens the “tight junctions” between intestinal epithelial cells, preventing bacteria and toxins from leaking into the bloodstream.
- Proline and Joint Health: Proline is an essential building block for cartilage repair. Combined with naturally occurring Chondroitin Sulfate and Glucosamine released from the bones, bone broth offers comprehensive mobility support. This is critical for senior cats, who often suffer from arthritis but are masters at masking their pain.
2. Active Hydration and Urinary Health
The kidneys are the organs under the most stress in a cat’s body due to their high-protein diet. Dehydration concentrates waste products in the blood and urine, overloading the nephrons.
- Umami Flavor: Bone broth provides a rich, meaty flavor (Umami) that cats are naturally drawn to. Adding broth to food increases voluntary water intake far more effectively than trying to force them to drink from a bowl.
- Diluting Urine: Increasing fluid intake dilutes the urine, lowering its specific gravity (USG). This reduces the risk of mineral crystals (like struvite or calcium oxalate) precipitating out of solution, which can cause life-threatening urethral blockages.
3. Liver Support and Detoxification
A cat’s liver has a lower capacity to metabolize certain compounds compared to dogs or humans. Glycine in bone broth is a rate-limiting amino acid for the synthesis of Glutathione—the body’s “master antioxidant.” Glutathione plays a central role in Phase II detoxification in the liver, helping cats process and eliminate environmental and dietary toxins more efficiently.
Risk Analysis: Pitfalls in Commercial Products
The popularity of bone broth has led to many products that are substandard or physiologically inappropriate for cats.
1. The Allium Toxicity (Onion & Garlic)
This is the single biggest risk when owners use human-grade broth or low-quality pet products.
- The Mechanism: Sulfur compounds in onions, garlic, and chives (like N-propyl disulfide) cause oxidative damage to hemoglobin in feline red blood cells, forming “Heinz bodies.” This leads to the rupture of red blood cells, resulting in life-threatening hemolytic anemia.
- Safety Threshold: Cats are far more sensitive than dogs. Even onion powder, common in human soup stocks, is enough to cause toxicity. Therefore, the non-negotiable rule for cat bone broth is “No Onions, No Garlic.”
2. The Sodium Burden
Cats have a limited ability to excrete excess sodium. Commercial human broths are often loaded with salt for flavor. Excessive sodium intake can raise blood pressure and exacerbate kidney and heart disease in cats. Specialized cat products typically have very low sodium levels or no added salt.
3. Controversial Additives
Some products add veggies, herbs, or thickeners (gums) to increase appeal or cut costs.
- Citrus/Lemon Juice: Often used to adjust pH for shelf stability. While large amounts are toxic, tiny amounts used for pH balance are generally considered safe by manufacturers, though sensitive cats may react.
- Tapioca/Potato Starch: Used to create a gravy-like texture. While not toxic, these are carbohydrates that offer no nutritional value to an obligate carnivore.

Brand Overview:
Caru is a family-owned brand built on offering true Human Grade products. Their broth comes in Tetra Paks (like soup stock), allowing for easy pantry storage until opened.
Ingredient Analysis:
- Standard: Produced in a human food facility, USDA verified.
- Ingredients: Grass-fed beef bones, organic carrots, celery, parsley.
- The Black Pepper Debate: The ingredient list includes “Black Peppercorns.” While large amounts of pepper can be irritating, Caru states they use trace amounts to aid digestion and turmeric absorption. Toxicological analysis suggests this level is safe, but owners of cats with ultra-sensitive stomachs should be aware.

User Experience & Insights:
- Aroma & Taste: The broth has a natural light golden color and a mild meaty scent with herbal undertones.
- Community Feedback: Cat owners frequently praise the resealable cap, which makes fridge storage easy and mess-free. There is a small segment of “super-sniffer” cats that may initially hesitate due to the scent of cinnamon, but most accept it readily when mixed with food.
- Efficacy: Many owners report glossier coats and more consistent digestive health after 2-3 weeks of use.
| Pros | Cons |
|---|---|
| Absolute ingredient transparency (Traceability). | Cinnamon/Turmeric scent can deter very picky cats. |

| Convenient, resealable packaging. |
#3. Native Pet Organic Bone Broth Powder
The Best Value & Most Convenient Solution
Brand Overview:
Native Pet focuses on minimalist, effective supplements. Their powder-based broth solves the biggest headache of liquid broths: the short shelf life after opening.
Ingredient Analysis:
- Ultra-Minimalist: Only 3 main ingredients: Organic Chicken Broth, Organic Chicken Protein, Organic Sweet Potato Powder.
- No Additives: No fillers, flavorings, or artificial preservatives.
- Concentrated Protein: As a powder, it boasts a massive 64% minimum protein content, providing a dense source of amino acids when reconstituted.
Nutritional Data:

User Experience & Insights:
- Convenience: One jar lasts a long time and creates as much broth as multiple liquid cartons, saving significantly on shipping and storage. Shelf life is up to 12 months.
- Texture: Users in online communities note that it requires warm water and vigorous stirring to dissolve fully; otherwise, it can clump. A popular “hack” among owners is sprinkling the powder directly onto dry kibble as a flavor booster (topper) rather than making a liquid, which cats seem to love.
- Palatability: The concentrated organic chicken flavor rates highly for acceptance.
| Pros | Cons |
|---|---|
| Long shelf life; no waste if the cat eats slowly. | Requires mixing with warm water. |
| Cost per serving is very economical. | Liquid texture is thin, lacks the “jiggle” of fresh gelatin. |
| Versatile: Use as a drink or a dry topper. |
#4. Primal Pet Foods Bone Broth (Frozen)
Primal Nutrition & Optimal Joint Support
Brand Overview:
Primal is a giant in the raw feeding space. Their bone broth philosophy is about preserving nutrients through freshness, which is why it is typically sold frozen.
Ingredient Analysis:
- Sourcing: Bones from cage-free chicken or grass-fed beef, antibiotic-free.
- Support: Organic Apple Cider Vinegar (helps extract minerals from bone), turmeric, ginger.

| Fresh taste, minimally processed. | Requires thawing/planning ahead. |
#5. Nulo FreeStyle Bone Broth (Pouches)
Variety & Convenience for On-the-Go
Brand Overview:
Nulo focuses on nutrition for active pets. Their bone broth line stands out for its wide variety of flavors and smart, single-serve packaging.
Ingredient Analysis:
- Variety: Available in Chicken, Beef, Turkey, Duck, and Salmon.
- Herbs: Uses basil and thyme for flavor.
- pH Adjuster: Contains a small amount of Lemon Juice. While citrus is generally avoided for cats, the amount here is minute, used solely to balance pH for preservation, and is widely considered safe in this context.
Nutritional Data:
- Protein: 0.5% – 1.0% (Lower than Caru or Open Farm; primarily a hydration fluid).
- Moisture: 99%.
User Experience & Insights:
- Packaging: Sold in small pouches or 2oz single-serve packets. This is a huge plus for single-cat households, preventing the waste of opening a large carton that spoils in a week.
- Palatability: The “Shreds in Broth” line (which includes meat bits) gets rave reviews because it satisfies the cat’s desire to eat and drink simultaneously.
| Pros | Cons |
|---|---|
| Single-serve packaging prevents waste. | Lower protein content in the broth itself. |
| Excellent variety for rotating flavors. | Contains lemon juice (safe trace amount). |

The Perfect Kibble Topper
Brand Overview:
Known for their freeze-dried raw foods, Stella & Chewy’s designed this broth specifically to make dry food more appealing.

- Ingredients: Cage-free chicken broth, pumpkin, ginger, turmeric, cinnamon.
- Safety: 100% Human Grade, no garlic/onion.
Nutritional Data:
- Protein: 3.0%.
- Fat: 0.05%.
User Experience & Insights:
- Design: The pouch has a convenient side spout for easy pouring.
- Palatability: Very high acceptance rate. Owners often use this to “save” a meal when a cat is bored with their dry food. However, the inclusion of tapioca makes it slightly less suitable for strict low-carb/keto raw feeders compared to Primal.
| Pros | Cons |
|---|---|
| Smart packaging spout design. | Contains Tapioca (starch/carbs). |
| Excellent for coating dry food. | Not a “pure” broth due to thickeners. |
| High palatability. |
#8. Made by Nacho Bone Broth

Ingredient Analysis:
- Flavor First: Highly concentrated broth from cage-free chicken.
- Gut Health: Added prebiotics (brewers yeast) to support digestion.
- The Salt Note: The ingredient list includes “Salt.” The brand clarifies this is a tiny amount (approx 0.04% as fed) to balance electrolytes. While safe for healthy cats, owners of cats with end-stage kidney issues or heart conditions should consult a vet.
Nutritional Data:
- Protein: 2.0%.
- Sodium: ~0.04% (Low, but added).
User Experience & Insights:
- The “Nacho” Effect: Feedback suggests this broth often wins “blind taste tests” against other brands. It is frequently cited as the “last resort” that finally gets a sick or anorexic cat to lap up liquid.
- Feline Focus: Unlike many brands that market to “dogs and cats,” this recipe is tuned specifically for the feline palate.
| Pros | Cons |
|---|---|
| Superior palatability for picky cats. | Contains added salt (albeit a small amount). |
| Formulated specifically for cats. | Mid-to-high price range. |
| Includes Prebiotics. |
#9. Solid Gold Bone Broth Meal Topper
Nutrient-Dense Meal Addition
Brand Overview:
Solid Gold creates a hybrid product that sits somewhere between a broth and a wet food treat.
Ingredient Analysis:
- Texture: This is not a clear liquid; it contains real shreds of chicken, tuna, or salmon suspended in the broth.
- Nutrition: Offers actual animal protein meat, not just bone-extracted amino acids.
Nutritional Data:
- Nutrient profile is richer than clear broths due to the meat content.
User Experience & Insights:
- Usage: Excellent as a snack or reward. However, it is not suitable for syringe feeding sick cats, as the meat shreds will clog the syringe.
- Hydration: Encourages cats to “eat their water.” Most cats will lick the broth dry and then eat the meat.
| Pros | Cons |
|---|---|
| Contains real meat shreds (higher nutrition). | Cannot be used for syringe feeding. |
| Highly engaging texture for cats. | Expensive if used as a primary hydration source. |
| Good variety of fish/poultry. |

Community Insights & Expert Tips
Through extensive social listening in online cat owner groups and forums, we’ve distilled these trends and practical tips:
1. “Back to Basics” vs. DIY Fatigue
There is a strong trend toward single-ingredient products. However, making bone broth at home is time-consuming (24+ hours) and smelly. Furthermore, skimming the fat perfectly is difficult, and excess fat can trigger pancreatitis in cats. As a result, owners are increasingly trusting brands like Primal and Open Farm to deliver homemade quality with verified safety and fat removal.
2. The Palatability Paradox
Ideally, the healthiest broth is the best, but not if the cat won’t touch it.
- Herbal Hurdle: Broths heavy in turmeric or cinnamon (like Honest Kitchen) are sometimes rejected by scent-sensitive cats.
- Flavor Winners: Caru and Made by Nacho consistently rank highest for pure “lick-the-bowl-clean” appeal, likely due to a focus on meaty/savory notes over herbal ones.
3. Pro Usage Tips
- The Temperature Trick: Never serve cold broth straight from the fridge. Cats rely on scent. Warm the broth slightly (to about body temp, ~100°F) to release the aroma. If it smells good, they are 90% more likely to drink it.
- The Ice Cube Hack: Liquid cartons expire fast (5-7 days). Owners suggest pouring the broth into ice cube trays immediately after opening. Freeze them, then thaw one cube at a time. This extends the product’s life from days to months.
- Protein Rotation: Don’t stick to just chicken. Rotate between Beef, Turkey, and Fish broths to provide a broader range of amino acids and prevent your cat from developing food boredom.
Conclusion: Choosing the Right Broth for Your Cat
Bone Broth isn’t a miracle cure, but it is a powerful tool in the nutritional arsenal, bridging the hydration gap in modern feline diets.
Based on our analysis, here are our final recommendations:
- Best Overall: Open Farm Bone Broth. The perfect balance of ethical sourcing, clean ingredients, and functional support.
