Zenapet today announced the release of Cat Colostrum Plus, a powdered feline supplement formulated to reflect emerging veterinary research on immune, digestive, and overall wellness support. The initiative highlights published studies on functional ingredients such as bovine colostrum, probiotics, mushrooms, yeast, spirulina, resveratrol, and bone broth—nutrients that are increasingly studied in companion animal health.
Bovine colostrum, the first milk produced after birth, has been examined for its concentration of immunoglobulins and growth factors. A peer-reviewed trial published in the Journal of Feline Medicine and Surgery reported that adding spray-dried bovine colostrum to kitten diets significantly boosted immune responses and gut health, including higher fecal IgA levels and stronger antibody titers following rabies vaccination. Researchers concluded colostrum may help bridge the “immunity gap” in young cats while stabilizing the gut microbiota during stress. Similar studies in dogs, published in the British Journal of Nutrition, found that colostrum-enriched diets strengthened antibody responses to vaccination and enhanced overall immune function.
Organic chicken bone broth provides natural collagen, amino acids, and minerals that support joint and digestive health. While clinical trials in cats are limited, research in canine osteoarthritis has shown that collagen-rich supplements can improve mobility and quality of life. Broth’s amino acids, such as glycine and glutamine, are also recognized for their roles in gut lining protection and repair. In veterinary practice, broth is frequently used to encourage hydration, stimulate appetite, and provide easily digestible nutrition for cats recovering from illness.
Probiotics are among the most widely studied supplements in feline nutrition. Research published in Topics in Companion Animal Medicine confirmed that the probiotic strain Enterococcus faecium SF68 reduced diarrhea incidence in shelter cats and antibiotic-treated animals. Other trials have shown that multi-strain synbiotics can relieve chronic constipation and megacolon, while yeast probiotics such as Saccharomyces boulardii improved microbial balance and short-chain fatty acid production. These findings highlight the role of probiotics in restoring gut health, modulating inflammation, and supporting immune resilience.
Functional mushrooms are also gaining scientific attention. Shiitake mushrooms contain lentinan, a beta-glucan that has demonstrated immune-modulating and anti-tumor effects in preclinical models. Turkey Tail mushrooms, rich in polysaccharopeptides, were the focus of a University of Pennsylvania School of Veterinary Medicine pilot study in dogs with hemangiosarcoma. That study reported extended survival times compared with historical controls, underscoring Turkey Tail’s therapeutic potential. While feline-specific mushroom trials are limited, these findings are being applied in integrative veterinary protocols.
Resveratrol, a polyphenol sourced from Japanese Knotweed, has been studied for its antioxidant and anti-inflammatory properties. A 2025 trial published in Veterinary Sciences found that obese cats receiving daily resveratrol supplementation experienced reduced triglycerides, improved inflammatory markers, and increased adiponectin levels without adverse effects. Researchers concluded that resveratrol may support metabolic balance in cats, complementing its established antioxidant role in other species.
Additional superfoods such as nutritional yeast and spirulina are supported by emerging feline research. A controlled trial in adult cats published in Frontiers in Veterinary Science found that yeast hydrolysate improved serum IgG levels and beneficial gut markers at moderate doses. Spirulina has been shown in canine studies to enhance vaccine responses and stabilize gut microbiota, while feline cell studies suggest it may stimulate macrophage activity and prime immune defenses.
Veterinary nutrition research also points to synergistic benefits when these ingredients are combined. Pairing prebiotic-rich colostrum or yeast with probiotics, for example, has been shown to improve gut integrity and immune outcomes more than either supplement alone.
“Scientific research in companion animal nutrition has expanded rapidly in recent years, and we believe it is important for pet owners to have access to these findings in a clear, responsible way,” said Casey Dawson, Head of Product Development at Zenapet. “Cat Colostrum Plus was formulated with these published studies in mind, reflecting both the promise and the limitations of current evidence. Our goal is to provide formulations that are clean, digestible, and aligned with what research suggests about feline health.”
Zenapet emphasizes that supplements should not replace veterinary care, and outcomes may vary by individual pet. The company works with a pet nutritionist with decades of experience in companion animal health to ensure its products reflect both research findings and practical insights from the field.
