L-lysine reduces the severity an. Review: Works well - Works well mixing it in with wet cat food. So easy! They feel and look so much better. Review: Really helps - I have three senior kitties. One carries Feline herpesvirus and the other two suffer from it. I had heard that l-lysine didn't work and was best to just skip, but my one kitty was noticeably becoming worse. He's 14, so it's almost to be expected that he would fare a bit worse than the 8 year-old. Snot was going everywhere, he was fevered, he wouldn't clean the snot off of himself (yay for bathing sick cats!), he ran fevers and you could tell that he just didn't feel well. Upon having him cleared by the vet, I tried this stuff. I mix it in their dry food and in wet food. My really sick kitty isn't 100%, but he's a good 85%. He cleans himself up, he plays, his nose runs a whole lot less, he sneezes much less, his fur looks better and his eyes are bright again. My other symptomatic kitty has SO much more energy and seems asymptomatic some days. She flies around the house at night again. I can't recommend this enough. Give it a shot. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004OA5ZLG | | Brand | Pet Health Solutions | | Brand Name | Pet Health Solutions | | Customer Reviews | 4.3 out of 5 stars 710 Reviews | | Global Trade Identification Number | 00814087005625 | | Item Form | Granule | | Item Weight | 136 g | | Item form | Granule | | Item volume | 5 Liters | | Item weight | 136 g | | Manufacturer | HealthyPets, Inc. | | Manufacturer Part Number | FELISYL35 | | Model Number | FELISYL35 | | UPC | 814087005625 885898084765 | | Unit Count | 3.5 Ounce | | Unit count | 3.5 Ounce | | Volume | 5 Liters | ## Product Details - **Item form:** Granule - **Item weight:** 0.3 Pounds - **Item volume:** 5 Liters - **Global Trade Identification Number:** 00814087005625 - **Manufacturer:** HealthyPets, Inc. ## Images ![Felisyl Immune System Support Granules - Support Healthy Tis - Image 1](https://m.media-amazon.com/images/I/71PUSN+yX+L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well *by E***7 on 23 February 2026* Works well mixing it in with wet cat food.
