I honestly thought this was unnecessary because my cat’s premium food says ‘complete and balanced.’  Then I learned that cooking and storage can destroy taurine, and it clicked. I started using PureTaurine+ just to be safe — and within a few weeks, she was more playful and her coat looked healthier than ever. I realized those labels don’t tell the full story, and I’m so glad I didn’t wait for something to go wrong.

I used to home-cook for Maisie thinking it was healthier. Then she started slowing down and the vet mentioned taurine deficiency — I felt awful. I found PureTaurine+, started one scoop a day, and within weeks she was brighter and playful again. More importantly, I finally stopped feeling that guilt every time I fed her.

I honestly didn’t expect to notice a difference but wow. My 9-year-old cat, Milo, was just kinda… slowing down. Sleeping all day, not really playing anymore. Someone in a cat group mentioned taurine so I tried PureTaurine+. About 3 weeks in he’s back to chasing the laser and even running up the stairs again. Didn’t change his food or anything else, just this.

Our Mission

We started Catlyst because cats deserve the best nutrients in the world, better than guesswork.


Most supplements on the market underdose, use cheap ingredients, and never verify what's actually in the bottle. We built something
different - something that cats actually need to thrive.


Taurine for heart and vision. L-Lysine for immune health. Omega-3 for skin, coat, and brain function. Dental+ to keep their mouth healthy
without the vet bill.


One brand. Everything your cat needs. Nothing they don't.
