Review: Healthy chews - Helps maintain my cat's immune system & they must taste good bc he loves eating them
Review: Cats recommend them 4 - 0 - Our vet suggested these for one of our cats. The cat Beau will be on Lysin for the rest of his life and the vet cautioned that they have had issues with some cats taking the Lysin. Well not these Lysin. We have a clowder of cats and in the morning they all line up for these Lysin bites. They love the taste, it does not cause any stomach issues or diarrhea, no stool softness. The treats do not smell or have an after odor. They seem very effective and have maintained our cats energy levels. If you are purchasing a Lysin product I can tell you these are the "treat" of choice for Mimi, Beau, Bobo, and Atticus. They come and remind me it is time for their treat.

## Questions & Answers

**Q: Did they recently change this product?  My cat use to love these treats and w/ my last bag she wont touch them - they look different to me too.**
A: Vetoquinol lied! Check the old package and it will not have a flavor. The new package will say liver flavor.  My cat will not touch the ones that are liver flavor. I am looking for a new product.

**Q: Have they changed the formula lately? they used to be beige and crumbly but now are dark brown and hard. One cat barfs them up,one can't chew it.**
A: I can't say if they changed the formula in that our cat has only been on the Lysine for about five months, and they have always been dark brown and hard (but somewhat moist).  Fortunately, our cat loves them, has no problem keeping them down, and they are doing the job of preventing secretions from the eyes.

**Q: How many treat are in the bag.**
A: I have a small scale and I measured out 20 treats which is 10 g. The bag I purchased is 180 g or 6.35 oz in net weight, so I believe that would be approximately 360 treats in a bag. The directions say to give your cat 6 treats for flare-ups (250mg). Also that your cat can have up to 12 treats a day. I hope this helps answer your concerns.

**Q: How many calories are in a 250 mg dose?**
A: Good question - the back of the bag doesn't give calories. Here is a comparison with Feline Greenies which is 1.25 calories per treat. For a 5 lb cat, they suggest 11 treats. For routine maintenance  Enisyl recommends 6 treats. Comparisons.in per cents - Greenies Crude Protein 27, Crude Fat 12, Crude Fiber 10 Enisyl Lysine Treats Crude Protein 30, Crude Fat 8, Crude Fiber 1. So, I'm guessing that each Enisyl Treat can't be more than a Greenie - 1.25  their website is: www.vetoquinolusa.comHope this is helpful. Oh, I had one vet tell me that when her cat had a flare-up, she gave her cat up to 15 or 18.

### ⭐⭐⭐⭐⭐ These really work and could save your cats' lives!!! These work better than the oral gel.
*by B***H on July 22, 2021*

This review is for "Vetoquinol Enisyl-F Lysine Bites: L-Lysine Chews for Cats & Kittens - Chicken Liver-Flavor". Let me start by saying that if your cats / kittens have the herpes virus (aka feline viral rhinotracheitis (FVR)) then these bites can save your cats' lives. I bought these for my sweetheart for the stray cats and kittens that she has hanging around her house that all got really, really sick and were all showing symptoms of FVR. This stuff is like a little miracle in each bite. After giving these bites to the one cat for a day, he didn't have a runny nose anymore. Then after the second day, he could meow again and the crusty stuff on his nose was gone. Then after the third day, the crusty stuff on his eye was going away, and he could open his eye again. By the fifth day, the respiratory problem seemed to be going away, and he could breathe right again. Now I'm not a vet nor is my sweetheart, so we can't say positively that these bites are a cure and didn't just help with the symptoms. BUT, these bites also helped some other cats and some kittens that had the exact same symptoms going on, and they got "better" also and just as quickly. I can't see where that is just a coincidence. We firmly believe that these bites helped save the lives of those cats / kittens. Now anytime the cats get a runny nose or something like that then my sweetheart gives them these bites for a few days and it seems to clear it right up. I had previously purchased the Vetoquinol oral gel for her for the cats and that seemed to work really well. These bites work SOOO much better and the cats seem to love the taste. (The oral gel must not taste as good because the cats didn't want to eat it after a while even though they seemed to love the taste in the beginning.) We highly recommend these bites and will definitely be buying more of these bites instead of the gel. They really work!!!!! Hope this helps and have a great and blessed day! :)
