Does your cat need supplements?

You've probably seen them in pet stores. Cat supplements are becoming increasingly popular. From a shiny coat to reducing stress: there seems to be a miracle cure for every ailment. But does it really work? Or is it mainly good for the brand's wallet? In this blog post, we delve into the world of cat supplements. When can they help, and when is it better to just rely on good food?

A shelf full of vitamins for yourself, but does your cat also need some supplements?

Not every cat needs supplements

Cats are naturally quite self-sufficient. If your cat is healthy, eats well and has plenty of energy, chances are they don’t need any supplements at all.

Start with the basics:

Is your cat eating high-quality cat food?
Are there no obvious signs like a dull coat, poor appetite, or anxious behaviour?
Is your cat a healthy weight and active?

Then supplements are usually unnecessary.

Are there exceptions?

Of course! Think of older cats, those recovering from illness, or cats with arthritis, digestive issues, or extreme stress. In those cases, supplements can be beneficial. As long as you know what you’re giving and why.

Popular supplements: what do they actually do?

Not all supplements are created equal. Here are a few common types:

Omega-3 (fish oil): Supports skin, coat, and joint health, especially essential for older cats.
Probiotics: Help maintain a healthy gut flora and support digestion.
Calming supplements: Often contain valerian, L-theanine, or tryptophan for anxious or stressed cats.
Glucosamine & chondroitin: Commonly used for joint stiffness or arthritis.

⚠️ Keep in mind: the effects aren’t clinically proven. Supplements for pets are classed as food, not medication meaning they aren’t strictly tested.

Be careful before you buy

Those shiny labels and bold promises can be tempting, but don’t fall for them. Cats are sensitive, and not every supplement is harmless

Here’s what to look out for:

Choose products made specifically for cats never for dogs or humans.
Check the dosage: too much of a certain nutrient can be harmful.
Make sure there’s no underlying health issue (like thyroid or kidney problems).
When in doubt, ask your vet first.

Still unsure?

Before adding any supplement to your cat’s diet, ask yourself:

Why do I want to give this supplement?
Does my cat actually have symptoms, or am I giving it “just in case”?
Have I discussed it with a vet?
Do I see any change after 2–4 weeks of use?

If you don’t notice any improvement, you may just have an expensive powder sitting on your shelf.

So… supplements or not?

Supplements can be helpful for cats, but not always. For most healthy cats, a balanced diet provides everything they need. Only in specific cases are extras useful, and even then, choose wisely and with professional guidance.
