Answer by Chewy • Mar 19, 2026
The Felisyl brand L-Lysine Immune & Respiratory Support Gel for Cats & Kittens is only available in a salmon flavor. Felisyl chicken-flavored soft chews and liquid concentrate are available.
Can this be added to wet food?
Answer by • Sep 29, 2025
The manufacturer recommends administering orally. A small amount can be placed on your cat's nose to stimulate taste interest. Once interest has been established, a syringe or teaspoon may be used. It can also be applied directly on cat's paw to allow cat to lick off.
