Give your feline friend the extra support they need during stressful times with Strawfield Pets L-Lysine Immune Support Granules for Cats. Featuring the essential amino acid L-lysine, this supplement helps calm your BFF and soothe their stress. This amino acid is also often recommended by vets for intermittent use in dealing with feline herpes virus (FHV), as L-lysine can help boost a helpful immune system response. Please note: It is recommended to take breaks with the use of L-lysine so supplementation doesn’t possibly cause a deficiency in the amino acid arginine. This convenient supplement is created with just two pure ingredients—L-lysine and chicken liver powder—to provide a clean formula you can feel good about and a tasty one your little buddy will love.
