Pet Honesty® Expands Award-Winning Dual-Texture Cat Supplements With New Tuna Flavor

Fastest-growing cat supplement brand in the U.S. introduces Tuna varieties of its popular Multivitamin and Hairball Support formulas

Pet Honesty®, the science-backed, vet-approved pet wellness brand and the number one and fastest-growing cat supplement portfolio in the U.S., is expanding its best-selling cat lineup with two new Tuna-flavored formulas: Dual-Texture Multivitamin Tuna and Hairball Support Tuna.

The new flavor offers pet parents another protein option for cats that may be sensitive to chicken or simply prefer a different flavor. Both products feature the same dual-texture format as Pet Honesty’s existing Multivitamin and Hairball Support supplements, with a crunchy shell and creamy center.

“We hear from cat parents all the time that finding a supplement their cat will actually eat can be a challenge, and having more than one protein option can make a real difference,”  said Greg Reinhart, Ph.D., Chief Science Officer at Pet Honesty. “That’s why taste is always top of mind during development, and we’re proud that 100% of cats loved the taste in our independent feeding study.” 

While palatability is central to Pet Honesty’s at-home feeding studies, we also look for specific benefits from products. The Multivitamin Tuna includes omega-3s, lysine, and postbiotics alongside a full vitamin lineup to support skin and coat, joints, heart, brain, digestion, and immune health. In an eight-week 2026 in-home feeding study, 93% of owners saw improved overall health and vitality, 93% saw improved quality of life, and 90% saw improved coat health.

Hairball Support Tuna combines omega-3s, citrus pulp, apple pomace, psyllium husk, and zinc to help move hair through the digestive tract while supporting skin and gut health. In the same study, 97% of owners saw fewer hairballs, 97% saw smaller and less intense hairballs, and 81% saw less shedding.

“Multivitamin and Hairball Support are two of our best-selling cat products, and we’re excited to give pet parents another way to incorporate them into their cats’ routines,” said Rich Greenberg, Chief Executive Officer of Pet Honesty. “We’re continuing to see strong interest in cat wellness and growing demand for more variety, whether that’s a new flavor, format, or size. From launching Cat Squeezables and 90-day supply options earlier this year to now expanding two of our most popular formulas into Tuna, we’re focused on giving cat parents more choices and meeting the needs of a category that has historically had fewer options.”

Both formulas are free of unnecessary fillers, artificial preservatives, and artificial flavors and were developed with the guidance of Pet Honesty’s Scientific Advisory Council of veterinarians, scientists, and animal nutrition experts.

Multivitamin Tuna and Hairball Support Tuna (3.7 oz, $15.99 each) will be available beginning September 15th at PetHonesty.com,  Amazon, Chewy, and TikTok Shop.
