Felisyl L-Lysine Gel for Cats - Immune System Support - Supplement Support for Healthy Tissue, Respiratory, and Vision - Salmon-Flavored - Made in The USA - 5 oz

my cats didn't like it, even stray cat didn't like. I mixed it with their favorite creamy treats but still they didn't touch it

So far, I am pleased with this Lysine gel for my Ragdoll Kitty. I got it because my kitty was suffering from red, irritated eyes with an occasional sniffle / sneeze. I decided to try and treat this internally rather than dealing with eye drops for this problem in her eyes since it would cause her stress and it is topical so the problem would probably continue without keeping that daily regimen up. I needed something systemic and more favorable to my kitty and she is treats and food driven. I was concerned a bit with some of the reviews dealing with quality control and I am happy to say that all is perfect. It smells great, and my cat loves it. She goes for it with the gusto of eating a Churu. She has only had several doses, but I can already see improvement in the redness in the whites of her eyes. I am so happy. Happy cat, happy life. I started on the minimum dose of 1/8th tsp twice a day and I wait to give it to her on a full stomach to avoid some of the digestive upset that can occur as a side effect. The amount you get in the tube is very affordable compared to others in oral drops or other powders and gels that are super expensive on dosing average. I also felt confident to purchase Felisyl due to it receiving the seal of approval from the NASC and believe it or not, during my research of Lysine products, it is even recognized under Good RX for its health benefits and prevention maintenance for my beloved feline along with several other vet formulated lysine products, but they were double to triple the purchase price. Very happy with my decision and hoping she continues to improve in her health, allergies and keeping her immune system well and strong. This product is so much cheaper than a Vet bill or repeat visits because the symptoms are only treated instead of trying to clear the underlying condition that this gel or more like a paste actually does for her internally and systemically. Allergies begone.

This stuff seems great! In just three days, a kitten who had one leaky eye closed, and another who was the worst off with crusted-over closed eyes and mucus oozing out the eyes and nose, were able to eat, drink, explore and groom themselves again! That first one looks, and acts, normal but I’m still administering the medicine to them and they love the taste. The second is making great recovery towards eating dry kibble on their own, and drinking water, but makes a fuss over ingesting the medicine, so I have to scoop some onto my finger, gently coax their mouth open while holding them in place by the scruff, and line their tongue with it. This one also turns away from eating canned food, now, which were never a problem before the upper respiratory issues occurred. The positives about this supplement are it seems to have a fantastically—almost—irresistible flavor cats and kittens love; it’s easy to squeeze out; finger-feeding isn’t difficult, just tedious. This product is quite creamy, with a teeny-tiny bit of stiffness similar to something like mayo; it’s not runny, until reaching its last few remnants that more so “sneeze” out of the tube rather than glide on like normal.🤣 The negatives lie within the instructions—in the sense that you’re supposed to give a certain amount, twice, daily for three to four weeks…with only five ounces of product!🤣 I bought this four days ago and practically ran into fumes by morning of that fourth day!🤣🤣 Of course, I’ve also been handing out dosages to about five outdoor-only cats (with those in the roughest shapes, who won’t lick the product off the spoon, temporarily brought indoors for the finger-feeding)! Even for someone not giving this supplement to multiple kitties who started getting the sniffles, sneezies, and the watery eye goop that kept them shut, this stuff still wouldn’t last the expected three to four weeks! Counting the dosages given daily, there have only been about 16 total, in that tube. If a single cat were receiving the recommended two servings a day, I guesstimate that would only last a little over two weeks—defffffinitely not reaching the three, let alone four, week expectation…which is a brilliant marketing strategy haha. And it worked, because I just ordered a second tube—but I am also exploring other options, and will likely leave the gel usage for those who refuse to lick it off a spoon, or any dab to their nose, and must be finger-fed. I’ve also been using it in conjunction with a high calorie supplement for those with the lowest energy, and had the scraggliest looks. Both supplements, together, are doing well! Overall, this product was perfect for my “Oh no! I need L-Lysine, fast!” situation, and has been showing results! They certainly haven’t been instant, but observing that kitten who was the absolute worst off, out of the rest of the stray colony, gradually perk up in the beginning stages of returning to normal gives a little relief that something MUST be working. They can open both eyes about halfway, now! My only gripe is, I wish this tube were at least triple its size—for the same price!🤣

Not really sure what to rate this, honestly. When the batch is safe, it’s an amazing product. My kitten loved the flavour and it nearly completely resolved her herpes symptoms. It also didn’t bother her tum at all, which was incredible because she has pretty bad IBD, most likely from surviving distemper as a newborn. That said, TWICE now when I’ve tried to reorder, the batch we’ve received was horrible. Immediately on opening it, it smells very off, almost like farts (lol). And Birdie (my kitten) notices it as well. It’s also very runny, nearly liquid rather than paste. She won’t touch it now. Though, with each new tube, she’s taken one tiny lick, which then makes her run away. Hours following her taste of the product, on both occasions, she’s developed horrible diarrhea, which is otherwise well controlled with special dietary food. It’s the only thing different about those days, so I’m certain it’s the lysine :( she really misses it. But it’s clear something is wrong with this batch. Hoping to try again in a couple of months maybe? Or not, if I can actually find a suitable alternative.

Gonna find out how it does soon but when I got it the bottom of the seal was busted and it was everywhere, all over the bag all over me, everywhere

Cats take it with no problem. I bought this to replace the expensive product ($ 45 !!) that the vet supplied previously. The Felisyl Gel has a higher Lysine concentration than the vet supplied product too. My cats get Churu treats (3) times a day (yes, I know, my boys are spoiled) and I've mixed this product with the Churu treats and given them the Felisyl without mixing with the Churu treats, they take it either way. L-Lysine really seems to clear up their respiratory problems like sneezing, runny eyes, etc. It really does have lab tested proven benefits for cats, so I'm going to keep them on it.
