“Taurine deficiency is one of the quietest problems I see in practice. By the time the signs show, the heart or the eyes have often already been affected. A measured daily dose of pure taurine is one of the simplest ways to protect a cat before that happens.”
Dr. James WhitfieldBVetMed MRCVS

Give once a day, mixed into food. One level scoop holds 500 mg of pure taurine; use the number of scoops that matches your cat's weight.

Casilia™ Taurine is an unflavoured, odourless powder. Sprinkle the scoop over wet food, moistened kibble or a spoonful of tuna water and stir it through. Most cats don't notice it at all.

For fussy eaters, start with a pinch for 2–3 days and build up to the full dose.

Frequently Asked Questions

Does taurine supplementation actually work for cats?

Yes. Taurine is an essential amino acid that cats cannot produce on their own and must obtain through diet. Studies show that taurine supplementation supports cardiovascular function, retinal health, reproduction, and immune response in cats. Many cat owners notice improvements in energy levels, coat quality, and overall vitality within 2-4 weeks of consistent daily use. However, taurine is a nutritional supplement, not a medication. It works by addressing deficiency, not treating disease.

How is this different from the taurine in cat food?

Commercial cat food processing destroys up to 50% of naturally occurring taurine through high-heat manufacturing. Even premium brands can't guarantee adequate bioavailable taurine after processing, storage, and exposure to air. Casilia™ Taurine bypasses this problem entirely—our pharmaceutical-grade powder hasn't been heat-damaged or degraded, so your cat receives the full potency with every scoop. Think of it like fresh vegetables versus canned: both contain nutrients, but one delivers significantly more nutrition per serving.

How often should I give Casilia™ Taurine?

Just one scoop of Casilia™ Taurine mixed into your cat's daily meal provides the essential amino acid support they need. Cats cannot produce taurine on their own, so consistent daily supplementation is key. The unflavored powder mixes into anything—wet food, moistened kibble, bone broth, tuna water, or homemade meals—without changing taste or texture. Most cat owners notice improvements in energy levels, coat quality, and overall vitality within 2-4 weeks. For best results, blend the appropriate dose (based on your cat's weight) thoroughly into your cat's food once daily, and even picky eaters will accept it without hesitation.

What if my cat won't eat it?

Casilia™ Taurine is an unflavored, odorless powder that disappears when thoroughly mixed into any type of food. For extra-picky eaters, start with a tiny amount (⅛ scoop) for 2-3 days, then gradually increase to the full dose. Many customers also find success mixing the powder with a teaspoon of tuna juice or bone broth first, then adding to food. Over 95% of "picky eater" concerns are resolved using these simple techniques.

Can I give too much taurine? Is it safe every day?

No, you cannot overdose on taurine. Unlike fat-soluble vitamins (A, D, E, K) that accumulate in the body, taurine is water-soluble, meaning any excess your cat doesn't need is simply excreted in urine. This makes daily supplementation completely safe for long-term use.

What if my cat already seems healthy? Do I really need to add this?

Prevention is always easier than treatment.

Taurine deficiency develops slowly and silently.. by the time symptoms appear (lethargy, vision problems, heart issues), damage has already occurred. Indoor cats, senior cats, and cats on dry-food-heavy diets are especially at risk, even if they "seem fine." Think of taurine like a seatbelt: you don't wait until after the crash. It's nutritional insurance that costs pennies per day but protects against thousands in emergency vet bills.
