Cat Immune & Respiratory Support

Support your cat's immune system, breathing and eye health with veterinarian-trusted L-Lysine supplements from Speerya. Cats cannot make L-Lysine on their own, yet this essential amino acid helps manage everyday respiratory challenges, sneezing, watery eyes and eye discharge linked with feline herpesvirus (FHV-1). Choose the classic powder that mixes easily into wet or dry food, or the maple-flavored gel that picky cats take without a pill fight. Both formulas are NASC certified and made for safe daily use in kittens, adult cats and seniors. If your cat catches every cold going around, sounds congested, or struggles with goopy eyes, start here. Shop cat immune and respiratory support supplements with clear dosing, honest ingredients and flavors cats actually like, delivered anywhere in the USA.
