If your cat deals with eye discharge, sneezing, or just needs an immune boost, this is a game changer. ### ⭐⭐⭐⭐ My cats love these *by S***E on November 20, 2025* I have had my cats on these for years now, I’ve lost count of the amount of packages that I’ve purchased. This is the only brand that I will buy because it’s the only brand that my cats will eat. I have to cut them in thirds for my cats or they are too tough to chew and they won’t touch them. I cut the tail off and then the main part in half, perfect size for them. Once I do that they get excited for their treats. I got one of my cats when she was 10 weeks old and noticed that she was sick right away. The vet explained that she had a cold caused by the feline herpes virus. She’s twelve now and if she doesn’t get the chews then she’ll have a cold within days. A couple of years later, I adopted a two and a half year old male cat that also has feline herpes. Without these chews his eyes get junky and he gets the cold symptoms just as quickly. They both know when it’s treat time and will sit in front of the counter and meow until I look at the clock. I recommend these to anyone that has a cat with feline herpes. If your cats won’t eat them, try cutting them in half, it might help; did with mine. ## Frequently Bought Together - VetriScience Lysine Immunity Health Chews, 250 mg Lysine Plus Immune Supplement for Cats and Kittens with Allergies, Sneezing, Runny Nose and Watery Eyes, Chicken, 90 Count - Felisyl L-Lysine Gel for Cats (5oz) – Supports Immune, Respiratory, and Eye Health.
