Cat Immune Support Lysine – Allergy Relief & Immune Health Supplement for Cats with L-Lysine, Colostrum, Quercetin & Omega-3 – Soothes Sneezing, Runny Nose & Itchy Skin Chicken, (30-Day Supply)

my cats love them and they work really great i’ve given them to my cats for 3 days now and ive seen a huge improvement with them being less sniffly and not coughing. highly recommended will be getting more if i need them after they finish the bag.

I recently tried the Cat Immune Support Lysine for my cat dealing with allergies, and I’m thrilled with the results! This supplement has noticeably improved her symptoms—less sneezing and overall discomfort. The easy-to-administer formula blends well with her food, and she doesn’t seem to mind the taste at all. I love that it supports her immune system while helping manage her allergies, providing a double benefit. If your cat struggles with allergies, I highly recommend giving this lysine supplement a try for better health and comfort!

Our wee little black panther kitty, about fifteen years old, developed a sneezing problem several months ago. Just little bouts of small sneezes, sometimes a couple of big ones. She's a delicate, easily stressed kitty, and she almost died during a dental cleaning years ago, some reaction to the anesthetics, so unless it's a life or death situation, taking her to the vet isn't an option. She's also showing signs of early CKD. So it was 'watch and wait'. The sneezing continued, not worsening or getting better. After consulting with an excellent AI (Anthropic Claude, leaps and bounds better than any of the others), it suggested giving her lysine, as an 'almost zero risk, could work' option to try. I've been giving them to her for a little over one month - and it's amazing how little she sneezes now. Sure, here and there a sneeze, but not like the multiple bouts of sneezing she used to have every day (again, they weren't over the top, she seemed unbothered by them, otherwise it would have warranted a vet visit). Now - maybe one sneeze in a day/day and a half. Giving too much lysine can be harmful, but it takes a really large amount to do so. Giving this little eight pound kitty eight to ten of these little crunchies is all she needs (its actually a low dose), and the results are great. Of course - this is not vet advice. If your kitty gets the sneezes, and they progressively worsen or are accompanied by other symptoms - go to a vet.

UPDATE 11/27/2025: Formula does what it claims. I have been successful at feeding several of these treats to my cat by stuffing 3-4 treats at a time into a cold pate meatball and sprinkled with kibble (Important to use cold pate to hold the meatball shape). I used to add a few treats to the meatball too but made my cat only want the treats and not eat the entire meatball. I would substitute one meatball for one meal until he ate a total of 12 treats for 12 lbs of weight (3-4 meatballs in total per day). Note, portion is 1 tbsp per feeding. Only after all meatballs have been eaten do I resume his regular meals for remainder of day. Several small meals per day prevents over-feeding and keeps your cat healthier and trim just like humans!😆Lol Regardless, my cat recently had been very sick with vomiting due to several factors and caused his leaky eye to return. After vet used anti-convulsant and bland diet for a few days, my cat was better. Then I slowly added his regular food to diet w/o these treats. By end of week, I added these treats in pate meatballs again. The Lysine in this formula coupled with the probiotics and fish oil have healed his leaky eye and improved his digestion. His skin and coat have always been in excellent condition due to the kibble formula I use. However, once my cat became ill his skin and coat became dry and dull. I am happy to say that these treats have put the health and shine back into my cat’s coat. The benefits of adding these into your cat’s diet far outweigh the inconvenience of making pate meatballs to entice eating them. So I will continue to use these treats as long as my cat will eat them. Original Review in May 2025: The package states it contains approximately a 30 day supply of treats depending on your cat’s weight. Directions state to give 1 chew per 2 lbs weight for kittens and 1 chew per 1 lb weight for cats greater than 6 months old. I have to feed my cat 12 treats per day because he weighs 12.5 lbs. These cat treats are about 1/2 inch wide by 1/4 inch high. See photos for reference. Be cautious though if your cat is pregnant or used for breeding because these treats have not been proven safe. Otherwise, It’s best to feed treats during or after a meal to reduce GI upset. My cat was excited to try something new and seemed to like it after a couple treats. So I gave him a few more treats. However, he stopped chewing and spit one out. I think he must have detected the fish oil or brewer’s yeast even though it is chicken flavored. In either case, he hates the taste of both! I was instructed by my vet to share a tiny portion of my fish oil gel capsules to prevent spit-ups, whatever the cause. He didn’t like it at first either and refused to eat his food. Now, I just cover his kibble and fish oil with wet cat food or liquid pate. I will try adding these chews as well to get my cat to eat them before I give up. If successful, I will give an updated review. I bought these chews hoping they will stop his one leaky eye, hot spot, and hairballs. I also hope these chews will work so I can quit sharing my fish oil gel capsules with my cat. It’s great for cat’s skin & coat, but an open capsule tastes as bad as castor oil!🤮🤮 No wonder my cat hates the taste!😆Lol Turns out the seasonings from table scraps were the cause of frequent vomiting. What can I say? Those Puss ‘n Boots eyes get me every time!😆Lol

These are great and my cat likes them. These have many health benefits for cats. He likes the crunch and then the soft middle. I recommend these cat supplements.

Unfortunately Neither of my cats would eat.

I started giving Pet Honesty Cat Immune Support Lysine to my 18-year-old cat because she occasionally picks up colds that really affect her energy. I’ve been trying to boost her immune system, and this supplement truly seems to help. Since starting it, she’s had fewer sneezing episodes and overall seems more comfortable. She actually likes the flavor, which is a huge plus—I just give it along with her treats and she takes it without any fuss. Knowing it includes lysine, colostrum, and omega-3s gives me extra confidence that she’s getting real support. So far, I’m very happy with the results and will definitely keep using it for her.

My cat loves all the vitamins I purchased for him. He is a furry family member and I want him to be as healthy as possible. I take vitamins for joint health and skin health. Why would I not buy them for my big beloved Dinker! 🤷‍♀️🩵😺

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.

Happy the kitties will get some vitamins...they like the taste and Im happy.

My kitty loves these and helps with his sneezing fits. He hasn’t been sneezing or stuffed up at all. So happy it worked. Well worth the money. I’ve bought these more than once and will continue to buy. My cats happiness is well worth it

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 les adores et elle est très sélective. Je recommande!
