Vet Backed Immune Lysine for Cats, Chicken, 30-Day Supply

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 severe allergies, and these treats have made an incredible difference for him. I can immediately tell when he’s taking them versus when he’s not, which is why I know they’re highly effective. He absolutely loves them and gets excited every time it’s treat time. The digestibility is excellent—he has had no stomach upset or digestive issues at all. The chewability is great as well, and he has no trouble eating them. The texture is similar to regular dry cat treats, but with a softer center that makes them even more appealing. The softness seems to make them easier for him to enjoy. Since my cat is on the larger side, I typically give him 13–14 treats first thing in the morning. I first found these after a vet visit where he was cleared of mites and diagnosed with severe allergies. I was searching for something to help with his skin irritation and allergy symptoms, and these turned out to be exactly what he needed. Before using these treats, he was constantly itching, sneezing, and even losing hair from scratching so much. His nose was often congested, and his breathing seemed uncomfortable. Since starting these treats, the itching and sneezing have stopped, his breathing has improved significantly, and his nose is no longer congested. He also seems much more comfortable overall, which has had a calming effect on his daily behavior. I’m extremely happy with the results and will continue purchasing these treats. They’ve made a huge difference in my cat’s comfort, health, and quality of life.

My 13 yr old cat has suffered from what seems to be allergies off and on. Runny nose, sneezing, boogers, etc. Tried another brand that came in a tube, he didn't love it and I didn't see any results. This product however. He loves! Thinks they are treats and after a week or so, he is so much better! Not to mention energetic and happy. I've had a number of cats over many years, this product has worked the best for this problem.

my cat has very watery eyes and a stuffy nose most times. grabbed this up just to see if she could get some relief and the watery eyes reduced significantly! i didnt notice anything else, positive or negative, except for the allergy relief which is what we needed anyway. she digested well. they are just small chew tabs that i throw in with her food. i docked one star because i have to give her ten of them at a time for a full "dose". that seems excessive and theres surely a way to condense that into less..... overall im happy with it (so is kitty)

Exactly what I ordered but my cats didn’t like them. I think they were a bit hard on their teeth.

My cats loved these. Helped with their allergies also. Will order again.

We’ve tried so many foods and treats that then we gave away, but not these. My cat loves them. He needs lysine, but the stuff by Rx was refused. This doesn’t have the same amount of lysine, but since he eats them…don’t care. He also loves the multivitamins. So now I love PetHonesty. I hope allergies are helped. Super customer care. Fast and thorough responses!

Not for picky cat eater - put them down & they wouldn’t even smell them; had to throw away.

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.

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.

I'm sure they are good but my fussy cat wont eat them.

Mon chat les adorent !!!! Quand j'oublie de lui donner le matin il les réclament avec appétit. Il commençait un rhume de chat, il avait des éternuements, une petite toux et après 3 jours a prendre la lésine les symptômes ont diminué jusqu'à disparaître. Je recommande !

My cat loves them! His last lysine treats were hit and miss. Sometimes he'd throw up ten seconds after eating one...or he wouldn't eat at all. These, he gobbles them up and begs for more! An easy way to get lysine into our little guy!
