A Thoughtful Approach to Cat Supplements
Looking for safe, effective supplements for your cat? Learn from a cert. holistic pet coach and feline nutritionist about which cat supplements help and which to skip for long-term health and wellness
If you’ve ever stared at your supplement shelf wondering which bottle might actually help your cat, or if they’ll even tolerate it, you’re not alone. I’ve been there too.
Supplements can feel like a maze, especially when you’re trying to support your cat in a gentle, holistic way.
As a feline nutritionist and holistic pet coach, I like to start with food, lifestyle, and emotional well-being. That’s the foundation. But sometimes, the right supplement, used with intention, can add an extra layer of support. Not as a quick fix, but as part of a bigger picture.
The Top Trends in Feline Supplementation
Cat guardians are getting so savvy. They’re:
Focusing on prevention with daily support like omega-3s, pre and probiotics, and multivitamins with minerals
Choosing natural, whole-food-based supplements over synthetic or filler-heavy formulas
Seeking personalized, condition-specific solutions instead of “one-size-fits-all”
I love this shift! It shows just how deeply people care about their cats’ long-term health.
Why More Cat Parents Are Turning to Supplements
We’re evolving. People are asking deeper questions about root causes—not just treating symptoms. They want to nourish their cats in ways that feel aligned, kind, and holistic.
And finally—cats are getting the spotlight they’ve always deserved. Most supplement advice used to be dog-centric. But cats? They’re different. They have unique physical and energetic needs. When we meet them where they are, they thrive.
That said, not every cat needs a supplement. A species-appropriate, balanced diet can do a lot. But I work with plenty of cats dealing with inflammation, gut imbalances, aging changes, or chronic conditions. That’s where thoughtful supplementation can help.
What I Use, Why I Use Them, and What to Skip
My Top 3 Most-Recommended Cat Supplements
These are the categories I turn to most in my practice to support cats emotionally, physically, and energetically.
1. Immune Support with Mushrooms
So many chronic conditions tie back to immune dysregulation. Mushrooms are one of my favorite wellness tools. I use them to support immune function, longevity, and even digestion. They are available in powders and tinctures. Right now, I’m rotating two specific mushrooms with my own cats, and they’ve been doing great with them:
Cordyceps – Also called the “caterpillar mushroom,” it’s phenomenal for supporting lungs and kidneys. It has a mild, almost toasty flavor that most cats tolerate really well. I usually start with about 50–100 mg per day and mix it into food.
Tremella – This one supports digestion and is full of antioxidants—great for older cats or those recovering from illness. Its prebiotic fibers feed the good gut bacteria. I use a tiny pinch (25–50 mg) and increase as needed.
Some mushrooms, like reishi, can be too bitter for my crew—but cordyceps and tremella? Total win.
Always use tested, high-quality mushroom supplements—no fillers or starch blends.
2. Omega-3 Fatty Acids
These are almost always one of my first suggestion. Omega-3s are amazing for inflammation, skin and coat health, joint support, cognition, heart health… the list goes on. I always recommend marine-based sources like calamari, sardine, or krill oil (not flax or chia—cats don’t convert those well). Bonus: many cats actually like the taste when you find a clean product.
Omega-3s help with:
Inflammation
Kidney and bladder function
Joint health
Skin & coat
Cognitive aging
Cardiovascular function
Best sources? Marine-based—calamari, sardine oil, krill oil, or green-lipped mussel. (Flax and chia don’t work well for cats.)
Bonus: you can alternatively give your cats food sources, such as whole sardines in place of the oils
3. Emotional & Nervous System Support
This one’s often overlooked, but energetic and emotional stress in cats creates physical symptoms. Cats are sensitive beings. Fear, trauma, grief, or overstimulation can throw off everything from appetite to litter box habits. Stress, trauma, and nervous system dysregulation can show up in cats as:
Digestive issues
Skin problems
Appetite changes
Behavior issues like isolation or aggression
Gentle tools I love:
Flower Essences – Australian Bush Flower or Bach Remedies
CBD – Great for seniors or anxious cats
Nervine herbs – Chamomile or skullcap
💗 Cats are deeply intuitive. When their nervous system is supported, everything else flows more easily.
Bonus Support Categories
These areas come up often in my consultations:
Kidney & Bladder Support: Start Sooner, Not Later
Even if your cat isn’t showing signs of kidney or bladder trouble, it’s wise to start supporting these systems preventatively. Kidney and bladder health are critical for cats, especially since they’re naturally prone to chronic kidney disease (CKD), urinary tract issues, and the formation of crystals or stones—particularly as they age.
And while no supplement can outshine a species-appropriate diet (that’s always the foundation), the right support can work with their food to create resilience in these vital systems.
Some of my go-to options include:
Omega-3s (from fish or krill) – Excellent for kidney inflammation and overall renal health. These healthy fats can help slow the progression of kidney changes and support circulation to these delicate organs. This is also a good preventative.
Glandular Kidney Support – Glandulars can be incredibly effective for cats showing early signs of kidney decline. Sourced ethically, they provide tissue-specific nutrients that help nourish and support function.
Herbal Tinctures – Carefully formulated blends for kidney and urinary support can be a game-changer. Look for cat-safe, alcohol-free options that include herbs like nettles, dandelion leaf, corn silk, or cleavers. These can help support kidney filtration, reduce inflammation, and promote detoxification in a gentle, effective way. I always start low and slow, based on the cat’s constitution and sensitivity.
Marshmallow Root – A gentle, soothing herb that supports the urinary tract lining and reduces inflammation. I love this for cats who’ve had UTIs or crystal issues in the past.
💡 Pro Tip: Hydration is everything when it comes to kidney and bladder health. Wet food diets, broths, and creative ways to encourage more water intake make a big difference.
Dental Health
Yes, dental support is a supplement category! Dental disease is incredibly common in cats, and it’s more than just a mouth problem—it can affect their kidneys, heart, and overall vitality. While brushing can help, it is not always possible, depending on your cat’s preference. Dental disease doesn’t just affect the mouth—it affects the whole body, especially kidneys and heart.
I use:
Liquid antimicrobials (natural and gentle)
Oral probiotics
Whole-food options like kelp or CoQ10
Paired with food and lifestyle adjustments, it can be a game-changer.
Digestive Support
I don’t use probiotics across the board, but when a cat has been on antibiotics or shows signs of digestive imbalance, I might bring in some support. A healthy gut is the foundation of everything. For cats with chronic issues, I often recommend:
Prebiotics and Probiotics – Species-appropriate, multi-strain
Digestive Enzymes – Especially for older cats or those with IBD
Soothing herbs – Like slippery elm or marshmallow root
(These aren’t needed for every cat, but they’re incredibly useful in transitions or recovery.)
Final Thoughts
The key to supplementation isn’t just what you choose—it’s why and how.
Cats are energetically sensitive. So I always consider:
Diet and nutrient gaps
Underlying conditions
Personality and stress profile
Ease of administration (texture, taste, delivery method)
And yes, sometimes intuitive guidance - I muscle test everything

I tried to sneak high grade fish oil into my cats food and he wouldn't touch it. Same with chicken bone broth instead of warm water. I haven't tried full canned sardines but I'm afraid he would do the same thing. I did manage to sneak in some pumpkin and marshmallow root to help soften his stool but goodness only knows how. He's really smart but he's turned up his nose at expensive diets too even though he usually loves chicken. No accounting for the tastes of a cat I suppose. I'm just grateful for the little things he has let me add.
I tried to pay for a subscription and that has me baffled as well. Came for the company certainly do not stay for the tech.
