Choosing food that works for both dogs and cats calls for a close look at the difference between a complete dry diet and a meal enhancer. I rank Wysong Fundamentals first for buyers seeking one high-protein, all-life-stages dry formula for both species. Wysong Epigen 90 is the more specialized pick, with a starch-free, 60% protein profile for adult pets whose caregivers want a concentrated dry food. For pets who need more aroma or moisture at mealtime, Caru Daily Dish Chicken Bone Broth is a practical topper, not a replacement for a complete diet.

The main tradeoff is how much of your feeding routine you want one product to cover. Fundamentals is the broadest everyday choice, but its dry texture and limited-ingredient approach will not suit every pet. Epigen 90 goes further on protein and starch avoidance, though that makes it a narrower fit and calls for a gradual diet change. Caru adds liquid and chicken flavor, but it does not provide the same role as a complete food. I compare them by intended use, species suitability, life stage, and how clearly each option fits a real feeding decision.

Key Takeaways
- Wysong Fundamentals ranks first as the most flexible complete dry-food option here: its listing identifies it for dogs and cats of all life stages.
- Epigen 90 is the specialist choice, with a listed 60% protein content and a starch-free formula; it is labeled for adults, not all life stages.
- Caru Daily Dish is a broth topper for adding liquid and flavor, so I would pair it with a suitable complete food rather than feed it as the sole diet.
- Both Wysong foods are dry chicken formulas, but Fundamentals is the broader everyday pick while Epigen 90 targets buyers seeking a more concentrated, starch-free profile.
- All three products have limitations: dry-food texture may not appeal to every pet, Epigen 90 has a narrower profile, and broth requires pouring and may be refused by picky eaters.

Wysong Fundamentals Canine/Feline Formula Dry Dog and Cat Food, 5 lb
Fundamentals earns my Best Overall position because it combines the broadest stated use in this lineup with a straightforward dry-food format. The listing describes it for dogs and cats at all life stages and for all breed sizes, making it the most flexible starting point for a household looking at one shared product. Its chicken-and-brown-rice formula is also described as limited-ingredient, with probiotics, enzymes, and micronutrients included. That package makes more sense as an everyday food candidate than Caru, which is specifically a topper rather than a stand-alone meal.
Its position above Epigen 90 comes down to breadth, not a claim that Fundamentals is more nutritious for every animal. Epigen 90 has the sharper specialty profile: it is starch-free and lists 60% protein, but it is designated for adult pets and may call for a careful change from the current diet. Fundamentals is the less narrow pick for a buyer prioritizing a shared all-life-stages formula, although the supplied description does not give a percentage for its protein content. Buyers who need a specific nutrient profile should compare the full label rather than infer one from the general high-protein claim.
The clear compromise is texture. This is a dry pellet food, so it will not satisfy a pet that reliably prefers wet meals, and the limited-ingredient approach may not cover every animal’s dietary needs. The five-pound bag is a manageable size for evaluating fit, but it also means households with multiple animals may need to plan replenishment. I would choose Fundamentals when broad species and life-stage coverage matters more than a starch-free specialization; I would skip it if a pet needs wet food or a veterinarian-directed diet.
Pros:- Listed for dogs and cats of all life stages and all breed sizes.
- Chicken-and-brown-rice formula is described as limited-ingredient.
- Includes probiotics, enzymes, and micronutrients according to the description.
- A more broadly positioned everyday dry food than the adult-focused Epigen 90.
Cons:- Dry pellet texture may not suit pets that prefer wet food.
- The description does not establish that its limited ingredient list meets every animal’s dietary needs.
- The five-pound bag may require frequent replacement in a multi-pet household.
Best for: Households seeking a chicken-based dry food described for both dogs and cats at all life stages and breed sizes.
Not ideal for: Pets that will not eat dry pellets, or animals whose diagnosed needs call for a specific diet not established by the product description.
- Brand:Wysong
- Formula:Fundamentals Canine/Feline
- Flavor:Chicken
- Age range:All life stages
- Food form:Dry pellets
- Claimed ingredient feature:Organic chicken
- Nutrient positioning:High protein
- Package size:5 lb bag
Our verdict“I rank Fundamentals first for its broad stated dog-and-cat, all-life-stages fit, while recognizing that its dry format and general formula will not suit every pet.”
Wysong Epigen 90 Starch-Free Canine & Feline Dry Food, Chicken, 5 Pounds
Epigen 90 is the specialist pick for buyers drawn to a starch-free dry food with a listed 60% protein content. Its chicken formula also includes probiotics, prebiotics, vitamins, and minerals, while the product is described as made in the USA. Compared with Fundamentals, the defining difference is not simply that both are high-protein chicken foods: Epigen 90 makes a specific starch-free claim and publishes a protein percentage, giving label-focused adult-pet caregivers a more clearly defined target.
That focus also explains why I place it behind Fundamentals overall. Epigen 90 is labeled for adult pets, whereas Fundamentals is presented for all life stages. Buyers feeding puppies, kittens, or animals at other life stages should not assume the adult designation covers them. A change to this more concentrated formula may also need to happen gradually, as the supplied product information notes. The listing’s high protein figure and starch-free positioning describe the product; they do not, by themselves, establish that it is appropriate for a particular animal or solve a health concern.
Compared with Caru, Epigen 90 is a complete dry-food candidate rather than a liquid accent for a meal. That makes it relevant to a different decision: selecting a daily food, not simply making an existing bowl more appealing or adding moisture. Its drawbacks are the narrow chicken-only flavor range and a profile that will not match every feeding plan. I would choose it when a caregiver has a clear reason to seek a starch-free, high-protein adult dry food and has checked the full label. If all-life-stages flexibility is the priority, Fundamentals is the better fit in this lineup.
Pros:- Described as starch-free, distinguishing it from the broader Fundamentals formula.
- Lists 60% protein content.
- Includes probiotics, prebiotics, vitamins, and minerals in the supplied description.
- Made in the USA according to the product information.
Cons:- Labeled for adults rather than all life stages.
- A significant diet change may require a gradual introduction.
- Chicken is the listed flavor, so the choice is limited for pets needing variety.
Best for: Caregivers of adult dogs or cats specifically seeking a starch-free dry formula with a listed 60% protein content.
Not ideal for: Puppies, kittens, or other pets needing an all-life-stages designation, as well as buyers who want multiple flavor options or have not established that this formula suits their pet.
- Brand:Wysong
- Formula:Epigen 90
- Flavor:Chicken
- Age range:Adult
- Food form:Dry
- Protein content:60%
- Formula feature:Starch-free
- Package size:5 lb
Our verdict“Epigen 90 is my pick for adult-pet caregivers who specifically want its starch-free, high-protein profile, but Fundamentals is the more flexible choice for mixed life stages.”
Caru Daily Dish Chicken Bone Broth, Dog & Cat Food Topper – 17.6 oz
Caru Daily Dish is the lineup’s convenience add-on, not a third competing dry food. This chicken bone broth is described as a liquid topper for dogs and cats of all life stages. Pouring it over an animal’s regular food can add moisture and chicken aroma, which may help caregivers make an existing meal more appealing. Its role differs from both Wysong foods: Fundamentals and Epigen 90 are dry-food options, while Caru is meant to accompany a meal rather than replace a complete diet.
That distinction puts it third in a roundup focused on dog and cat food, but it can be the right purchase for a household that already has a suitable main food. The listed ingredients are chicken broth, turmeric, and yeast extract, and the product description identifies it as grain-free, non-GMO, preservative-free, and free from onion and garlic. Those claims may appeal to buyers seeking a simple broth-style topper, yet they do not make the product nutritionally interchangeable with a complete food. I would check the label and serving directions before using it, especially if a pet has a restricted diet.
Against the dry Wysong options, Caru is the only choice designed to add liquid rather than supply the central meal. The tradeoff is hands-on use: it needs to be poured and measured, comes in a carton, and may not appeal to a picky pet despite its chicken flavor. Its limited flavor selection also gives less room to vary the bowl than a broader product line might. Choose Caru when the priority is a broth topper for an established feeding routine; skip it if you need a stand-alone food or want a dry formula that can form the main diet.
Pros:- Liquid format adds moisture to an existing dog or cat meal.
- Described as suitable for dogs and cats of all life stages.
- Chicken broth, turmeric, and yeast extract are the listed ingredients.
- Product information identifies it as grain-free and free from preservatives, onion, and garlic.
Cons:- A topper is not interchangeable with the dry foods as a complete meal.
- Requires pouring and measuring for each use.
- Some pets may refuse broth, and the listed flavor selection is limited.
Best for: Dog and cat caregivers who already feed a suitable complete food and want a liquid chicken-broth topper to add moisture or flavor.
Not ideal for: Anyone seeking a complete stand-alone diet, or a pet that rejects broth, needs a different flavor, or requires a veterinarian-directed ingredient plan.
- Brand:Caru
- Product type:Chicken bone broth meal topper
- Flavor:Chicken
- Target species:Dogs and cats
- Age range:All life stages
- Food form:Liquid
- Listed ingredients:Chicken broth, turmeric, yeast extract
- Container and size:Carton, 17.6 fl oz
Our verdict“Caru is the clear choice for adding broth to a suitable existing diet, but I would not select it in place of a complete dog or cat food.”
How We Picked
I compared these three products by asking what job each one can reasonably do in a dog-and-cat feeding routine. Two are dry foods, while Caru is a liquid topper; treating all three as interchangeable meals would give buyers the wrong impression. I gave the strongest position to the option with the broadest stated use across species and life stages, then separated a more specialized adult formula from a product designed to supplement an existing meal.
My ranking also reflects how directly each description supports its intended role. Species and life-stage fit matter when a household is considering shared feeding, so I distinguish Fundamentals’ all-life-stages claim from Epigen 90’s adult designation. Formula differences matter next: Fundamentals is described as limited-ingredient with chicken and brown rice, while Epigen 90 is identified as starch-free and lists 60% protein. Those features may appeal to different buyers, but neither alone proves that a food is right for every individual animal.
I also weighed practical drawbacks, including dry texture, restricted flavor choices, a potentially gradual diet change, and the extra handling involved in measuring a liquid topper. Product descriptions do not establish that a food will resolve a health problem or suit every pet with a sensitivity. I therefore avoid treating broad wellness language as a medical guarantee. For pets with diagnosed conditions, special nutritional requirements, or a history of food reactions, I would ask a veterinarian to review the full diet and ingredient information before changing foods.
| dog and cat food | Brand | Formula | Age range | Food form |
|---|---|---|---|---|
| Wysong Fundamentals Canine/Fel | Wysong | Fundamentals Canine/Feline | All life stages | Dry pellets |
| Wysong Epigen 90 Starch-Free C | Wysong | Epigen 90 | Adult | Dry |
| Caru Daily Dish Chicken Bone B | Caru | — | All life stages | Liquid |
Factors to Consider When Choosing Best Dog And Cat Food
I would start by deciding whether you need a complete food or a topper. That choice separates Caru from the two Wysong products before you compare ingredients, age ranges, or feeding routines. After that, match the formula to each animal’s life stage and any veterinary guidance, then consider texture, ingredient profile, and how much preparation you want at mealtime.
Decide whether you need a meal or a meal enhancer
Fundamentals and Epigen 90 are presented as dry foods; Caru is explicitly a broth topper. That difference should guide the first decision. A topper can add liquid and flavor to a meal, but it should not be treated as a complete diet simply because it is marketed for both dogs and cats. If your goal is to select the main food, compare the two Wysong products and confirm the full nutritional statement on the package. If the main food is already chosen and you only want to add broth, Caru is the relevant option here.
I would also account for how the pet actually eats. A cat or dog that prefers wet food may not welcome a bowl of dry pellets, while a pet that turns away from a new broth may leave a topper unused. The listed product formats are useful clues, but individual preferences still matter. When introducing any new food or topper, follow package directions and watch whether the animal continues eating normally.
Match life-stage claims to the animals in your home
Among these products, Fundamentals has the broadest stated age range: all life stages. Epigen 90 is labeled for adults. That distinction matters in a mixed-age household, particularly if a buyer hopes to use one dry food across young and mature animals. I would not read the adult label as suitable for puppies or kittens simply because the formula is designed for both canine and feline consumers.
Caru also lists all life stages, but that describes its stated use as a topper; it does not turn it into a complete food for a growing animal. When one pet has different nutritional requirements from another, shared feeding may not be a good shortcut. Check the product’s full feeding directions and seek veterinary guidance for young animals, pregnant or nursing pets, or pets with health conditions.
Compare the two dry formulas by their actual differences
Fundamentals is the broader pick: it is described as high-protein and limited-ingredient, with organic chicken, brown rice, probiotics, enzymes, and micronutrients. Epigen 90 is more specific, with a starch-free claim, a listed 60% protein content, and probiotics and prebiotics. These are meaningfully different positions, but a buyer should not assume that a more concentrated or more specialized label is automatically better for an individual dog or cat.
Read the package’s ingredient and nutrient information alongside any advice from a veterinarian. The product descriptions do not provide every detail needed to determine suitability for allergies, medical diets, or all nutrient targets. Fundamentals makes sense when broad life-stage positioning is central; Epigen 90 makes sense when an adult pet’s caregiver is intentionally seeking its starch-free, high-protein profile. If neither matches a pet’s needs, choosing another formula is a better outcome than forcing a fit.
Treat ingredient and health claims as clues, not guarantees
Terms such as limited ingredient, probiotics, prebiotics, and human-grade can help narrow a search, but they do not establish that a food will prevent allergies, improve digestion, or treat a condition. An animal can react to an ingredient even when a formula is described as limited-ingredient. Likewise, a broth topper’s listed ingredients do not establish that it is appropriate for every restricted diet.
If a dog or cat has recurring symptoms, a known allergy, kidney or urinary concerns, or another diagnosis, I would share the full label with a veterinarian before making a change. For a healthy pet, compare the complete ingredient panel and feeding statement rather than relying only on a short feature summary. The right choice depends on the animal, not on the broadest marketing claim.
Plan for texture, serving routine, and a gradual change
The practical differences here are simple but consequential. The Wysong choices are dry, while Caru is liquid and requires pouring and measuring. A broth topper may fit caregivers who want to add moisture to a regular meal, but it creates another step and may be refused. A dry formula can be easier to portion and store as a regular food, yet it will not satisfy pets that expect wet meals.
Epigen 90’s description notes that some pets may need a gradual diet change. I would take that seriously rather than switching abruptly, and I would follow the manufacturer’s directions or veterinary advice for a transition schedule. Monitor appetite and tolerance, and pause to seek professional advice if concerning symptoms appear. Fundamentals’ broader age-range claim does not remove the need to introduce a new food sensibly.
Choose by household fit rather than by one headline feature
For a household seeking one dry option with the broadest stated use across dogs, cats, and life stages, Fundamentals leads this comparison. If the animals are adults and the caregiver specifically wants a starch-free formula with a listed 60% protein content, Epigen 90 is the more focused choice. If the main food is already settled and the goal is extra moisture or chicken flavor, Caru belongs in the bowl as a topper rather than in the same category as a complete meal.
Those distinctions also show when to skip each product. A pet that rejects dry food is a poor match for either Wysong formula. A young animal is not a clear match for Epigen 90’s adult designation. A buyer who needs a complete food should not rely on Caru alone. Starting with these exclusions can make the final choice clearer than selecting by a single ingredient claim.
Frequently Asked Questions
Can I feed the same food to both my dog and cat?
Both Wysong products are described as canine-and-feline formulas, and Caru is listed for dogs and cats, but that does not mean every shared feeding plan suits every animal. Fundamentals has the broadest stated life-stage range here, while Epigen 90 is labeled for adults and Caru is a topper. Check the complete label and feeding directions for each pet, and ask a veterinarian before using a shared diet for animals with different life stages or health needs.
Which product is the best choice as a complete dry food?
Fundamentals is my broadest-fit dry-food pick because it is described for dogs and cats of all life stages. Epigen 90 is also a dry-food option, but its adult label and starch-free, high-protein positioning make it more specialized. Caru is a liquid topper, not a substitute for a complete food. For either Wysong product, check the package’s full nutritional statement and confirm that it matches your pet’s needs.
What is the main difference between Wysong Fundamentals and Epigen 90?
Fundamentals is positioned as a limited-ingredient, high-protein chicken-and-brown-rice food for all life stages. Epigen 90 is labeled for adults, is described as starch-free, and lists 60% protein. I would choose Fundamentals for broader stated life-stage flexibility and consider Epigen 90 only when its more specific profile fits the adult pet. The product descriptions alone cannot determine which formula is right for a particular animal.
Can Caru chicken bone broth be fed as my pet’s only food?
Caru is identified as a meal topper, so I would use it to accompany a suitable food rather than treat it as a complete diet. Its liquid format can add moisture and chicken flavor, but the supplied information does not present it as a stand-alone nutritional meal. Follow the package directions and consult a veterinarian if your pet has a restricted diet or health condition.
How should I switch my pet to one of these products?
Follow the feeding directions on the package and introduce a new food gradually, especially when changing to Epigen 90, whose description notes that some pets may need time to adjust. A topper also needs to fit the pet’s existing diet, so check serving guidance rather than pouring an unmeasured amount. If your pet has a medical diet, a history of food reactions, or develops concerning symptoms, ask a veterinarian for an appropriate plan.
Conclusion
My recommendation depends on what you need the product to do. For the broadest stated dry-food fit across dogs, cats, and life stages, I would start with Wysong Fundamentals. For caregivers of adult pets specifically seeking a starch-free formula with a listed 60% protein content, Wysong Epigen 90 is the more targeted option, provided the full label matches the animal’s needs. If you already have a suitable main diet and want to add liquid and chicken flavor, Caru Daily Dish is the practical topper.
I would skip the dry Wysong foods for pets that will not eat pellets, avoid Epigen 90 when an all-life-stages designation is needed, and avoid relying on Caru as the main meal. Those limits are the point of the ranking: Fundamentals wins for versatility, Epigen 90 for a narrower adult formula goal, and Caru for adding broth. For any pet with a diagnosed condition or special nutritional needs, let the veterinarian help match the complete diet to the animal.
