Greenies Cat Dental Treats Review: Do They Work? (2026)
Greenies Feline Dental Cat Treats are built around a genuinely different job than a standard reward treat: the crunchy texture is engineered to scrape tartar and plaque down to the gumline rather than just taste good, and it's the most vet-recommended dental treat brand on the market. At under 2 calories per piece it's easy to fit into a daily routine, and it comes in chicken, salmon, tuna, and catnip flavors for pickier cats. The tartar-reduction claim comes from Mars' own in-house testing rather than a VOHC-certified study, and feeding it correctly means following the weight-based dosing chart rather than just tossing out treats freely.
Pros
- Formulated specifically to reduce tartar and plaque via mechanical crunch action
- #1 veterinarian-recommended cat dental treat brand
- Less than 2 calories per treat
- Reaches down to the gumline unlike standard crunchy treats
- Available in chicken, salmon, tuna, and catnip flavors
Cons
- 36% tartar-reduction claim is in-house Mars data from 2010, not independently VOHC-certified
- Feeding correctly requires following a weight-based dosing chart, not free rewarding
Overview
Most cat treats exist purely to get tails wagging — Greenies Feline Dental Cat Treats have a second, more clinical job: scraping tartar and plaque off teeth on the way down. Mars Petcare markets Greenies as the #1 veterinarian-recommended cat dental treat, and the 9.75 oz. Oven Roasted Chicken tub reviewed here is the brand’s standard everyday size for a single-cat household.
The pitch isn’t subtle — this is a functional treat first and a flavor treat second, aimed at owners who want daily dental support without wrestling a toothbrush into a cat’s mouth twice a day.

Greenies Feline Dental Cat Treats Dental Health Performance
Mars Petcare cites in-house testing showing a 36% reduction in tartar accumulation over 28 days of daily feeding, with the treat’s crunch engineered to break apart against the tooth surface and reach down to the gumline the way a standard crunchy treat doesn’t. Greenies markets itself against four veterinary assessment areas — plaque, tartar, gum health, and breath — rather than just “dental support” as a vague claim.
The caveat worth knowing: that 36% figure comes from Mars’ own 2010 data on file, not an independently administered, VOHC-certified clinical trial. Greenies’ cat treat line does not currently carry the Veterinary Oral Health Council seal that some dental chews hold, so the dental claim should be read as manufacturer-reported rather than third-party verified.
Palatability & Texture
Because the crunch has to survive contact with teeth long enough to do mechanical work, Greenies has a firmer bite than a soft-center treat like Temptations Classic — some cats take a session or two to adjust to the texture, particularly older cats or those used to softer treats. Once accepted, though, the brand’s position as the most vet-recommended dental treat suggests acceptance rates are strong across a broad cat population, and the four available flavors give owners room to find one their cat prefers.
The trade-off for the dental-first design is that it reads less like an impulse reward and more like a daily-routine product — cats build a habit around it rather than mobbing the pantry the way they might for a purely palatability-driven treat.
Value & Feeding Guidelines
At approx. $9.99 for the 9.75 oz. tub, Greenies costs more per ounce than a straightforward crunchy treat like Temptations, which tracks with the added manufacturing complexity of a dental-mechanic shape. The feeding chart is weight-based — roughly 8 treats twice daily for a 1 lb. reference cat, scaled up for larger cats — which means Greenies works best as a planned daily dental routine rather than a free-reward jar left open on the counter.
For owners specifically trying to manage tartar buildup between vet cleanings, that structure is a feature, not a limitation — it’s designed to be fed consistently, not sporadically.
How Does It Stack Up Against the Competition?
