Kittens love them, pricey though
I adopted two kittens from the local shelter, they both love these bits they are a good size and thickness, in addition to the flavor. They do seem to help them I notice less sneezing or other issues. However they tend to get really hard before they can finish a bag and I go through one bag in two weeks giving them to two kittens twice a day they are both over 6 months old I give them 7-8 each twice a day instead of what the bag says of 12 twice a day. Here lately it seems like they don’t really want them because they have become too hard to eat. Value for the money is not as good as I’d like, they are expensive. I know quality products cost more. Considering that I am feeding two kittens, with taxes it is around $48 a month for two bags for just supplements that help their immune system. I may have to look into another brand as it is a bit costly when you add in what I pay for kitten food, litter and any other extras for two.

Work Great!
I bought these for my 10 year old cat who sneezes nonstop. I originally bought the lysine paste. That was perhaps the most tedious and annoying task for both the cat and I! The cat would run away from me and it was just horrible! I stopped giving her the lysine for years and just dealt with the disgusting nasal discharge that I got to clean up, everywhere. Somebody recommended these treats. I was hesitant, but I have been using them for 10 days. I instantly noticed less sneezing and the cat was able to breathe better. But, I didn't believe it until I forgot to give her the treats one day and when I came home she had so much nasal discharge, she was miserable. I have been giving her the max dose daily of 12 treats. I space them out and give her 6 in the morning and 6 at night. I was hoping to only give her 6 treats, once a day so that it would save time, but it's not hard and the cat loves them! She gobbles them right up. The are "soft", in the beginning, but after maybe 4-5 days the treats start to get a little harder. They still have a slight, softness to them, but they aren't overly moist.

Formula has changed for the worst!!
I have three cats who require lysine. These treats were my go-to until now. They have changed the formula and it is now terrible -- only one of my three cats will touch them now. In the past, the treats have been small, dark brown, uniform in size, and sort of chewy. My cats went crazy for them. But the last package I ordered contained treats that were pale, crumbly, and not uniform in size. They looked old/stale/damaged, so I thought it was a bad batch and returned that package. I purchased another from a different seller and received the same thing -- the second package contained the same pale powdery treats. Looking through the reviews and product questions, it is clear that the company has changed the formula. However, I see some people saying the pale ones are the new formula, and other people saying the dark brown ones are the new formula. For me, the pale ones are new, and they suck -- I want the dark brown ones from the past. I emailed Vetoquinol directly from their website to ask for clarification, but they didn't bother to respond. So on top of my general dissatisfaction, I am also really underwhelmed by their customer service. I'm attaching a picture to show the two versions. On the left is the pale crumbly version that they seem to be selling now; if you squeeze these or try to break them, they just dissolve into powder (and the bag had a good one inch of powder in the bottom). On the right are the smaller dark brown ones that my cats have enjoyed in the past -- you can see in the picture that these can be torn into smaller pieces with no crumbling. Since apparently it isn't possible to get the small dark brown ones anymore, I am forced to find another brand. I find it really disappointing that the company would mess around like this on a product that many of us rely on to keep our cats healthy, and that we pay a premium for ($25+ per bag!). If they had responded to my inquiry, I might feel a little less disgusted, but they didn't, and I see others posting here who tried to get answers but were also ignored. I think that stinks, just like these new treats do. (PS - Both sellers I bought from were fine, no complaints there. This is purely an issue with the manufacturer.) UPDATE: Well it seems they have now settled on a new formula that is totally different from the versions I mention in this review. Now the treats come in new packaging (plastic pouch with a clear front panel), and the treats are dark-ish brown, super dense, and hard as a rock. My cat can't chew them, and I can't break them with my fingers, but I am able to cut them up with a sharp knife. The cat will then eat the small pieces. I don't know what is going on at Vetoquinol, but they sure seem to be going further and further downhill. Unbelievable.

These really work and could save your cats' lives!!! These work better than the oral gel.
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! :)

Our 10-year-old, male cat absolutely loves these. I gave him one to sample and he tried climbing up my leg to get to the bag in my hand immediately afterwards, this is not something he does. It has only been a few days that he has been taking them now, so not sure of the health benefit effect, very much hoping they help with his upper congestion & sneezing, which doesn't seem to be getting much better no matter what the vet prescribes.

Not one of my three cats will touch these.. I have a cat with Feline Herpes virus and I use the same brand lysine paste for her, but she will not touch these

We have 3 cats in our household and all of them refuse to it these treats. One of my cats tried a piece and immediately spat it out. I totally understood why when I tried to chop one piece with a knife to add it to their wet food.....they are so hard to cut, never mind about chewing these things! Whole package went strait to the garbage!
