Greenies Feline Dental Treats: Catnip vs Tuna for Cats

The real difference is flavor and bag size, not dental function

Both Feline Greenies Catnip Flavor and Tempting Tuna Flavor are crunchy dental treats for adult cats. The catalog describes the same core job for each: cleaning teeth, reducing tartar buildup, and freshening breath. They also share the same nutrition profile—natural ingredients, essential vitamins and minerals, nutritionally complete and balanced for adult cats, no artificial flavors or preservatives, and less than 2 calories per treat. So the choice comes down to which flavor your cat prefers and how much you want to buy at once.

That said, the two bags are not the same size. The Catnip version comes in a 4.6 oz pouch, while the Tuna version is a 9.75 oz value size. That size difference affects cost per ounce and how long a bag lasts, but it does not change what the treats do. If your cat has never tried either flavor, start with the smaller bag to see which one your cat actually likes before committing to the larger size.

Side-by-side: Catnip 4.6 oz vs Tuna 9.75 oz

• Flavor: Catnip flavor vs Tempting Tuna flavor. Both are designed for adult cats; flavor is the main sensory difference.
• Bag size: 4.6 oz pouch (Catnip) vs 9.75 oz value size (Tuna). The tuna bag holds more than twice as much by weight.
• Price: Catalog price is $5.10 for the 4.6 oz Catnip and $10.19 for the 9.75 oz Tuna. At list price, the tuna value size costs more per bag but less per ounce.
• Dental function: Both are described as crunchy dental treats that clean teeth, reduce tartar buildup, and freshen breath. The catalog does not claim one works better than the other.
• Nutrition: Both are nutritionally complete and balanced for adult cats, made with natural ingredients plus vitamins and minerals, with no artificial flavors or preservatives, and less than 2 calories per treat.
• Vet recommendation: Both carry the same claim: the #1 vet-recommended feline dental treat in the U.S., based on recommendations from U.S. veterinarians who recommend dental treats for at-home oral care.

When the 4.6 oz Catnip bag makes more sense

Choose the smaller Catnip bag if you are introducing dental treats for the first time or if your cat is picky about flavor. A 4.6 oz pouch lets you test whether your cat accepts the catnip flavor without committing to a larger bag. It also suits multi-cat households where one cat may prefer catnip and another may prefer tuna—you can buy small bags of each and let the cats vote.

The catnip flavor may also appeal to cats that enjoy catnip toys or catnip-scented items. However, the catalog does not state whether the treat produces a catnip response, so treat that as a preference question rather than a guarantee.

When the 9.75 oz Tempting Tuna value size pays off

The tuna value size is the better buy if you already know your cat likes tuna-flavored treats and you want to stock up. At $10.19 for 9.75 oz, the cost per ounce is lower than the catnip pouch at its $5.10 list price. That matters if you plan to use dental treats regularly as part of your cat's oral care routine.

The larger bag also makes sense for multi-cat households where everyone likes tuna, or for owners who like to use treats in dispenser toys for enrichment. Just keep the bag sealed and stored properly to maintain freshness—the catalog does not provide specific storage instructions, so follow general pet food storage practices.

What the catalog confirms about each treat

• Greenies Feline Dental Treat Catnip 4.6 OZ: FELINE GREENIES Catnip Flavor Dental Cat Treats come in a 4.6 oz pouch and are described as nutritionally complete and balanced for adult cats, with no artificial flavors or preservatives and less than 2 calories per treat. Confirms the smaller bag size and the shared nutritional profile, so you can compare size and flavor without expecting a nutritional difference.

  

• Feline Greenies Tempting Tuna Flavor Value Size 9.75 OZ: FELINE GREENIES Tempting Tuna Flavor Dental Cat Treats are sold in a 9.75 oz value size and are also described as nutritionally complete and balanced for adult cats, with no artificial flavors or preservatives and less than 2 calories per treat. Shows that the tuna option offers more treats per bag while keeping the same core dental and nutritional claims.

  

How many Greenies to give a cat: what the catalog does not say

The supplied product information does not include a feeding amount, daily frequency, or a transition schedule for either flavor. That is a decision limitation: you should not guess a number based on bag size or calorie count alone. For a specific recommendation, ask your veterinarian—especially if your cat has special dietary needs or is on a weight-management plan.

What the catalog does say is that each treat contains less than 2 calories, and that the treats are intended for adult cats. It does not state suitability for kittens. If you are unsure whether dental treats are appropriate for your cat's age or health status, your vet is the right source.

A practical way to choose between the two

If your cat has never had Greenies, buy the 4.6 oz Catnip bag first. It is the lower-cost entry point and lets you see whether your cat accepts the texture and flavor. If your cat likes them, you can move to the 9.75 oz Tuna value size for better cost per ounce—or stay with catnip if that is clearly the favorite.

If you already know your cat likes tuna-flavored treats, skip the small bag and go straight to the value size. The price per ounce is lower, and the larger bag reduces how often you need to reorder. Either way, both options deliver the same crunchy dental action and adult-cat nutrition, so you are not sacrificing dental benefits by choosing one flavor over the other.
