If you have a cat that struggles with sneezing, watery eyes, or seasonal allergies, this supplement is a total game changer. My cat used to have frequent sneezing fits and occasional itchy skin, especially after spending time near open windows or during seasonal changes. Since starting these I-Lysine treats, I’ve noticed a clear improvement in her breathing and overall comfort. I love that this formula goes beyond basic lysine. The combination of L-Lysine, Quercetin, and Colostrum really makes this feel like comprehensive immune and respiratory support. It’s reassuring knowing the antioxidants help defend against irritants while omega fatty acids support her skin and coat. It feels like it’s working from the inside out instead of just masking symptoms. The biggest surprise? She actually gets excited for them. The crunchy outside with the creamy center and chicken flavor must be irresistible because she eats them like a treat. For picky cats, that alone is worth five stars. I’ve also sprinkled them over food with zero issues. I really appreciate the clean ingredient profile — no fillers, no artificial colors or preservatives — and that it’s made in the USA by a NASC member company. That kind of transparency matters when it comes to my pet’s health. Overall, this has helped keep the sneezing, itchiness, and runny eyes at bay while supporting her immune system year-round. Happy cat, happy owner. Highly recommend to any cat parent dealing with allergy struggles!

My cat has seasonal allergies. She loves these and they work. Do not upset her delicate digestive system. Better than probiotic powder. Easier to administer she just eats them.

Excellent buy. Helped my kitty. She is a picky eater but she so loved this. The flavor is very appealing to her. She always looks forward to this daily treat that’s not only delicious to her taste buds but also helps her allergies.

Mon chat de 10 ans a eu une période d'éternuements (allergie) et quad j'ai vu et lu ce produit, me suis dite, je ne perds rien. Alors, je lui en ai donné une fois par jour, selon son poids. Et ça n'a pas été long, il éternuait moins et ensuite, plus du tout.

One of my cats needs lysine supplements. However, he hates the Optixcare L-Lysine chews (the Vet recommended ones). I can’t get my cat to eat these. So I tried to find other alternatives. I found these, my cat loves them, but they are small. I find there are not many for the price, but he serms to really enjoy this alternative lysine snack.
