So Far So Good. Kitty Approved!
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.

Very Palatable For Cats
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.

It's a Miracle!
I was really skeptical about this but I read the reviews and decided to give it a try. My cat, Grayson, has developed allergies and we cannot figure out why or to what. One vet said to use a Lysine powder and sprinkle it on his food. I did that everyday for about a year and it didn't do squat. I found a puree treat-like product that worked the first time but they changed the formula and it doesn't work and he won't touch it anymore. So, that was a big disappointment. I tried a bunch of other drops, treats and other things that didn't help either. I tried a saline mister. I would shut us in the bathroom with the hot water running, so the bathroom would steam up and give him a little bit of relief. I gave him a bath. That didn't help. My poor guy was suffering, coughing, and sneezing up thick snot. He sounded like Chewbacca when he was sleeping. We went to a cat only vet and she couldn't figure it out either. It wasn't a repiratory infection because we tried anitbiotics and it didn't give him any relief. We tried to figure out what he was allergic to but we couldn't figure it out...not food...not wool rugs...not litter...not plants...not dust...etc...we were at a loss. When I found this, I was really hesitant to buy it but this was my last ditch effort. I read the reviews and reread the reviews and thought what did I have to lose. This is what I found: He doesn't like the taste. I was hoping he would but no luck. I couldn't hide it in a treat or food. I put it on his paw and he walked around for 20 minutes pretending it wasn't there before he gave in and licked it off. I read one review that said she put it on her cats mouth/nose area while it was sleeping and then it had to lick it off. That sounded like a good idea. I have found that trick or putting it on his paw when he is sleeping works too. It took Grayson a full week and then suddenly he cleared up. I couldn't believe it! I was shocked and so happy. He's snoozing next to me right now and I can't hear him. I can't hear him approaching from the next room anymore. He's my fuzzy little ninja now! He's running around, seems to have more energy and seems happier. I don't notice any type of a strong smell. It's supposed to suppport his immune system and since he cleared up, I think it has helped his health. It's definitely helped my mental health because I'm not worrying about him all the time. I just pray that they don't change the formula because I would like to keep him on this long term. I do want to mention, that I gave it to him once a day for a week. Once he cleared up, I didn't give it to him for a couple of days, he was definitely sneezing and getting stuffy again. I put him back on until he cleared up...maybe 3-4 days and stopped again. He's been clear for about 4 days now. I'll give it to him as needed, when he starts to get stuffy again. I like that it doesn't have to be everyday forever. I'm keeping my fingers crossed that this is my long term solution.
