Feline Greenies Adult Dental Cat Treats Tempting Tuna Flavor
Verified Jun 10, 2026
These crunchy dental treats for adult cats use chicken meal as the main protein source, with grains like wheat, rice, and corn gluten meal to form a texture that helps scrub the teeth. They’re low in calories per piece and fortified with vitamins, minerals, taurine, and methionine so they can be fed alongside a regular complete diet. The formula is flavored with tuna and poultry fat to make them appealing while providing some dental-cleaning benefit through chewing.
From a nutritional standpoint, these are well-formulated dental treats that fit comfortably into most adult cats’ diets when fed in moderation. They offer a solid protein level for a treat, are low in calories per piece, and include added taurine and a full vitamin-mineral mix. They’re best suited as a dental-support snack for healthy adult cats who tolerate chicken and grains and already eat a balanced main diet.

At a Glance
KibbleLab Review
Strengths
- Chicken meal as the first ingredient provides a defined, animal-based protein source rather than vague meat by-products.
- Low calorie density per treat (about 1.4 calories) makes it easier to use these regularly without adding a lot of extra energy, as long as the main diet is adjusted slightly.
- Fortified with essential nutrients, including taurine and multiple vitamins and minerals, which supports overall nutrition for adult cats when used as directed.
- Crunchy, fiber-containing formulation can help provide some mechanical cleaning of the teeth while chewing, which may support dental hygiene.
Considerations
- Chicken meal and poultry fat are common triggers for food allergies in some cats, so these treats are not ideal if your cat has known poultry sensitivities.
- Grain ingredients such as wheat, rice, and corn gluten meal are prominent; while generally safe and nutritious, they may not suit cats that require a grain-free or more limited-ingredient approach.
- As with any treat, these should make up only a small portion of daily calorie intake, so you’ll need to slightly reduce the main food to avoid gradual weight gain.

Top 5 Ingredients Explained
01
Chicken
Chicken is a common animal-based protein in dog and cat foods, supplying essential amino acids, B vitamins, and energy-dense fats that support muscle maintenance, growth, and overall health; for cats it also contributes toward dietary taurine but must be present in sufficient amounts or provided via supplementation. It is prized for its digestibility and palatability, though some pets develop sensitivities or allergies to chicken, and nutritional value and safety depend on ingredient quality and processing—raw chicken carries pathogen risks and whole bones can pose choking or GI hazards.
02
Wheat
Wheat is a common cereal grain used in pet foods as a source of digestible carbohydrates, some plant-based protein, B vitamins, minerals, and dietary fiber, and it also helps with kibble texture and binding. It provides energy and fiber for many dogs but can cause food allergies or gluten sensitivities in a minority of pets and is generally less ideal as a primary ingredient for obligate carnivores like cats, so pets with known grain or wheat sensitivities should avoid it and calorie intake should be monitored to prevent weight gain.
03
Brewer's Rice
Brewer’s rice is a milling byproduct of rice processing made up of small broken white rice kernels commonly used in pet foods as a highly digestible carbohydrate source, filler and binder that provides readily available energy for dogs and cats while contributing little protein, fat or fiber. It is generally gentle on the stomach and cost‑effective, but diets using it must supply other ingredients for essential nutrients; pet owners should note its relatively high glycemic load (relevant for weight or diabetic pets), the potential for trace environmental contaminants associated with rice, and not confuse it with brewer’s yeast.
04
Corn Gluten
Corn gluten (often listed as corn gluten meal) is a concentrated plant-based protein and kibble-binding ingredient commonly used in dry pet foods to boost protein content, energy density, and help with texture. It provides digestible protein for dogs but is relatively low in essential amino acids like lysine, is not an ideal sole protein source for obligate carnivores such as cats, and can be a sensitivity/allergen for some pets, so it’s best used alongside high-quality animal proteins and complementary ingredients.
05
Poultry Fat
Poultry fat is a concentrated animal fat commonly added to dog and cat foods to boost palatability, texture and caloric density while supplying essential omega‑6 fatty acids (e.g., linoleic acid) and, in some cases, arachidonic acid important for cats. Because it is calorie‑dense and can oxidize during processing or storage, quality and preservation matter; overuse can contribute to weight gain and highly sensitive animals may rarely react to trace poultry proteins present in rendered fats.
