Review: 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.
Review: 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.

## 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.

### ⭐ Formula has changed for the worst!!
*by F***G on May 13, 2015*

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.
