Manna Pro Products LLC, a manufacturer of livestock feed and large-animal health care items, is moving into the cat and dog market.

The Chesterfield, Mo., company reported Dec. 11 that it acquired Nutri-Vet LLC of Boise, Idaho, and in a second transaction, the Petnology Essentials line from 21st Century HealthCare Inc. of Tempe, Ariz. The terms were not disclosed.

Nutri-Vet makes a variety of supplements—from Hip and Joint Advanced Strength Chewables for dogs to Multi-Vite Paw-Gel for cats—as well as medical products such as antimicrobial wound spray. The acquisition includes the Nutri-Vet and Optimal Pet brands and private-label manufacturing.

Petnology Essentials’ product line ranges from a bladder care supplement for dogs to tear stain pads for cats.

“Manna Pro’s acquisition of Nutri-Vet and Petnology are complementary extensions of our company that will benefit customers and the brands in our portfolio,” said Beth Rogers, vice president of marketing.

Nutri-Vet co-founder Steve Twohig called Manna Pro “a successful company that has been a recognized leader in the care and nurturing of animals.”

“Demand for high-quality companion animal products continues to grow, and consumers will benefit from Manna Pro’s experience, resources and innovation,” Twohig said.

Nutri-Vet and Petnology Essentials will operate together under the name Nutri-Vet Wellness LLC.

Manna Pro Products sells primarily to farm hobbyists. Its flagship Calf-Manna is a protein-rich supplement made for horses, cattle, pigs, goats and other species.
