Cats are often seen as low-maintenance companions, but they may still need supplements to support their health and well-being. The feline supplement market is one of the fastest-growing segments in pet health, with an expected annual growth rate of 8.7 percent through 2029. With so many available options, choosing the right supplements requires careful consideration.

Changing Interests of Pet Owners

A recent survey of pet parents conducted by market research publisher Packaged Facts reported that 76 percent of dog and cat owners were interested in finding health and wellness products for their pets. Nearly half of the respondents said that they were paying closer attention to their pets’ health in the aftermath of the COVID-19 pandemic.

According to the American Veterinary Medical Association, the number of U.S. households with at least one cat grew from 25 percent in 2016 to 29 percent in 2022. As more families welcome cats into their homes, interest in long-term feline wellness continues to rise. An aging pet population and the growing availability of veterinarian-formulated supplements further contribute to this rising trend.

Foundational Supplements

To promote general feline wellness, Sherman’s top supplement recommendations fall into the following three categories:

 1.     Immune Support: Medicinal mushrooms such as reishi, turkey tail and shiitake are rich in beta-glucans, which help modulate the immune system and reduce inflammation.

2.     Omega-3 Fatty Acids: Marine-based sources such as anchovy or krill are preferable. “Cats are obligate carnivores,” Sherman explains. “It’s essential they receive bioavailable, animal-based omega-3s rather than plant-based sources, which are harder for them to convert.” These nutrients contribute to skin health, joint function, cardiovascular well-being and cognitive performance, making them indispensable for cats of all ages.

3.     Emotional Wellness Support: “Cats are deeply sensitive creatures, and their emotional state directly affects their physical health,” says Sherman. “Supplements that support the nervous system, including certain adaptogens or vibrational remedies like flower essences, can be incredibly helpful, especially for cats dealing with anxiety, transitions or trauma.”

Targeted Support

Beyond the foundational supplements, others can be added on a case-by-case basis as specific needs arise. Sherman recommends a comprehensive assessment of the animal’s diet, lifestyle, health history and symptoms, noting, “I evaluate food quality and variety, energy levels, digestion, coat condition and behavior. If the cat thrives on a balanced, species-appropriate diet with no signs of imbalance, supplements may be needed only for foundational support like omega-3s. Life stage and unique needs are also considered. Kittens, seniors, stressed cats or those recovering from illness often benefit from targeted supplementation to optimize their health.”

In cases of chronic kidney disease, hyperthyroidism or taurine deficiency, especially in cats fed home-cooked diets, targeted supplements may be necessary. These situations often require meticulously adjusted nutrient levels and additional support, such as glandulars (organ-based supplements) or adaptogens (stress-modulating herbs), tailored to the cat’s specific condition. In such cases, oversight by a veterinarian and/or nutritionist may be advisable.

Supremacy of a Healthy Lifestyle

Supplements are often viewed as a quick fix for health issues. Without addressing root causes such as poor nutrition or unresolved medical conditions, supplementation may lead to poor results. In some cases, they may even mask symptoms rather than support true healing. “One of the most important things to understand is that supplements can’t replace a high-quality diet or proper veterinary care. They’re powerful tools, but they work best as part of a holistic wellness plan,” says Sherman.

Dosages and Other Safety Concerns

A common misconception is that more supplements are better. Cats often thrive with less. “Over-supplementation can strain organs like the liver and kidneys and may even contribute to the very issues we’re trying to resolve,” Sherman explains. “Just because something is natural doesn’t mean it’s always safe or necessary. Cats are incredibly sensitive, and even beneficial ingredients can become harmful if used improperly.”

The selection of supplements should be purposeful and precise. Fat-soluble vitamins A and D can accumulate in the body over time and lead to toxicity. According to VCA Animal Hospitals, vitamin A toxicosis in cats, often caused by excess raw liver or supplement intake, can result in joint pain, lethargy, weight loss and skeletal deformities.

When selecting cat supplements, Sherman recommends looking for those made with high-quality, naturally derived ingredients and no synthetic additives or fillers. Choose species-appropriate formulations and brands that employ good manufacturing practices. Companies that share third-party testing results are best.

Exercise caution with essential oils, particularly those incorporated into other supplements, as they can be harmful to cats if not used properly. It is best to work with a professional experienced in essential oil use for animals.
