Buy Pet Health Supplies PHS Felisyl L-lysine Gel for Cats (5 oz) at desertcart UK. Review: 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. Review: We recently got a new cat - about 2 years old - from a shelter. She was having issues with runny eyes, runny nose, and occasional wheezing. The vet said this was common and recommended Felisyl. She loves the taste - I was mixing it in with her Churu but now I just dollop it on top of her food and she licks it up. It does seem to help her symptoms. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00MO9SHBE | | Best Sellers Rank | 184,575 in Pet Supplies ( See Top 100 in Pet Supplies ) 55 in Nonprescription Cat Medications | | Brand Name | Felisyl | | Customer Reviews | 4.4 4.4 out of 5 stars (2,011) | | Flavour | Felisyl | | Global Trade Identification Number | 00814087006547 | | Item Form | Gel | | Item Volume | 5 Fluid Ounces | | Manufacturer | Pet Health Supplies | | Manufacturer Part Number | FEL6547 | | Model Number | FEL6547 | | Target Species | Cat | | UPC | 814087006547 | ## Product Details - **Brand:** Felisyl - **Flavour:** Felisyl - **Global Trade Identification Number:** 00814087006547 - **Item form:** Gel - **Item volume:** 5 Fluid Ounces ## Images ![Pet Health Supplies PHS Felisyl L-lysine Gel for Cats (5 oz) - Image 1](https://m.media-amazon.com/images/I/61B+fxs0M+L.jpg) ![Pet Health Supplies PHS Felisyl L-lysine Gel for Cats (5 oz) - Image 2](https://m.media-amazon.com/images/I/71BFax6e6YL.jpg) ![Pet Health Supplies PHS Felisyl L-lysine Gel for Cats (5 oz) - Image 3](https://m.media-amazon.com/images/I/712QUdjt9zL.jpg) ![Pet Health Supplies PHS Felisyl L-lysine Gel for Cats (5 oz) - Image 4](https://m.media-amazon.com/images/I/71DIKuT0rQL.jpg) ![Pet Health Supplies PHS Felisyl L-lysine Gel for Cats (5 oz) - Image 5](https://m.media-amazon.com/images/I/810SVO3WONL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by K***E on 5 January 2026* So far, I am pleased with this Lysine gel for my Ragdoll Kitty.
