Cons
  • None

Great way to give L Lysine
January 12, 2023
These small treats are a great way to get the recommended dosage amount of 1000mg L lysine for cats that need it. We have 4 that really need the full amount of this supplement daily. The powder must be placed wet food and is not always appealing. These treats work more often and much more easy to dose with two small bites.
Pros
  • easy dosing
  • well tolerated
  • most cats like the flavor and will eat them for a snack
Cons
  • must be careful not to feed too many as they look like regular dry cat food
  • they can be on the dry side and some cats may not find this palatable

Good product but pellets are hard.
August 31, 2020
I originally got a package of these from my vets and my cat loved them. I bought them from Entirely Pets because they were way less expensive. I got two bags but the one I opened has hard pellets. My poor old lady cat can’t bite into them. I plan to let EntirelyPets know.
Pros
  • Inexpensive
Cons
  • Too hard

Actual product different than description
April 18, 2018
The product I received is great, a tasty treat with added immune benefits... However, its not the product pictured here. The website clearly says "Lysine Treats" but the package I received says "Lysine Bites" .... Even the list of ingedients is different. Idk if the manufacturer has changed the product or if Entirely Pets has confused 2 different products.

Review for Enisyl-F Lysine Treats (6.35 oz)
January 3, 2017
I have two cats and neither one liked the smell well enough to even taste them. A waste of money.

Ebi loves these!
July 17, 2016
I first purchased some lysine treats at the pet store. Ebi would not eat them. They were a lot less expensive but she would not have anything to do with them. I gave her the Enisiyl-F Lysine treats and she really enjoyed them! She has kitty herpes so I hope this helps her not to have repeat outbreaks. She stopped sneezing and having her eye drip, so they seem to be working. Yay!

Lysine-f treats
July 4, 2016
My cat easily eats these treats. My only concerns are: there is no calorie content included in the information re the product and that the treat sizes are not consistent, leaving smaller mm sizes at the bottom of the package.
By cats m.
Excellent product
July 1, 2016
We originally started using these treats at the recommendation of our vet for one of our cats who had the herpes virus and suffered from respiratory problems. It eased those symptoms and was accepted readily in her food. After that cat passed away unexpectedly from other problems, we noticed some sneezing and respiratory indicators occurring intermittently in our other four cats. This wasn't surprising, as they all shared the same food and water bowls and all had the same mother (the problem could have been genetically transferred). Since then we've given all four of the cats the treats on a daily basis and it has definitely alleviated or lessened most of the respiratory issues. As an added plus, all the cats love the taste and will take them as stand-alone treats if we increase the dosage when symptoms are noted.

Great Product

My cat was diagnosed with feline AIDS 10 months ago. My Vet recommended Enisyl-F Lysine Treats as a supplement. She has responded very well. The cost through Entirely Pets is 1/3 less than what I was paying at my Vet's office. I highly recommend this product for feline AIDS.

Enisyl treats
March 31, 2016
I have been giving my cat Enysil treats for a few years and it seems to be curbing the number of episodes of ocular herpes flare ups. Plus my kitty loves them. My recent delivery of treats was not received because the mailing envelope was severely damaged and the contents were missing. I phoned Entirelypets and explained what happened and they shipped another order out immediately. They obviously know what good customer service is all about.

Enisyl-F Lysine Treats
March 14, 2016
I give my cat 6 pieces every day. Since I began about 1 and 1/2 yrs ago, her flare-ups have significantly decreased. She looks for them every day. Great find, especially for a picky princess who does not get excited over most food or treats.
By Mrscee
This works!
February 15, 2016
My cat was constantly getting eye infections. Since I started giving him the Lysine treats (which he likes!!!), he only gets the problem one or two times a year and not nearly as severe, thus I am not constantly taking him to the vets for prescription eye drops$$$.

Product Changed Again
February 7, 2016
I have several cats that use Lysine to combat their herpes symptoms. They don't like any other brand lysine treat, so I've had them on the Enisyl-F Lysine Treats from Vetoquinol for many years. This is the 4th change in the treats from this company. My cats loved the first and third version. They think the current (4th version) is okay. They eat a few nuggets and then are not interested anymore. Getting them to eat 6 treats twice a day is impossible. I was glad to read reviews from other people before I tried the new version. Normally I purchase several bags at a time but this time I only bought one bag. Because I have multiple cats, the treats make it easy to make sure each one is getting the correct dosage. Since my cats do not like this product any longer, I will go back to the powdered Lysine. It's more work since I will have to feed each cat separatly but on the bright side, it's less expensive. If your cat likes the taste of the treat - it's a great product.

upset!!
January 12, 2016
My cats won't eat now! I understand the formula has not changed, but from one bag to the nest they won't eat it! My one cat really needs it and I don't know what to get it now!!!

What Happened to the Formula???
January 7, 2016
My kitties always loved this brand of Lysine "treats".I even had them on auto-ship.Then one day they arrived in new packaging and along with it,I think a new formula.The newer "treats" are as hard as rocks,and for one of my smaller cats I like to break them up into even smaller pieces and can't at all with these..I personally thought they were stale,so I opened another package and same thing..just as hard...Only one of my cats will still eat them,but then again he would eat just about anything to be honest. :D I will not be buying this brand anymore..

Great alternative to the Enisyl-F paste
December 23, 2015
One of my cats has a sensative stomach. He will sometimes throw up the paste. The chews are a great alternative that he really likes. He will follow me around trying to get me to give him more of his "treats." The chews seem to work as well as the paste in controlling his symptoms.

Not really treats
November 3, 2015
One of my cats refuses to eat these while the other one occasionally will eat them. At first he seemed to really like them. So I'm not sure how good they taste! But I will keep trying as my vet recommended them.

Cat no longer eating the lysine
October 24, 2015
It worked outstandingly for many months but she has refused to eat the lysine from the last two bags I have purchased. My male cat who is on it has not cared and eats them still. I also remember a white version as well as a darker version and wondered what happened to the white version. I had purchased them at the vet. I am anxious to get this straightened out as she has symptoms again.
By Elllie
Treat form is great!
October 16, 2015
Was thrilled when I found the product in treat format instead of gooey very expensive can sold by a vet and had to be mixed with wet food. My cat will run from any place in the house when I tell her it's time for her "meds". My only problem is that the bags don't close correctly and treats will dry out if I don't move them to a zip lock that will keep them fresh.
By Kittysm
Did the formula change?

My cats have loved these for years. When the new package arrived, the treats looked different and my cats won't touch them. What happened?

Kitty won't eat anymore
October 13, 2015
I'm not sure why the company can't get the flavor right but kitty really has started to snub her nose at these. She really needs them so I don't know what to do...please make them tasty.

Enisyl-F Lysine Treats
October 2, 2015
My cats are so picky I have had to hide the treats in their food and even then they sometimes just eat around them. This product does seem to be helping with their fur after they got into some major fleas outside. I've hd to dose them twice with Advantage II and powder them with diatomaceous earth "BIO-D" to bring the flea problem under control not to mention spraying my yard.

Lysine Treats go down well
March 12, 2015
Brought these from entirely pets as opposed to buying them from our vet. I give 4-6 daily to our cat with the Herpes issue and he is not a big cat treat eater I just use some cat psychology. Product is fresh and unlike some of the reviews I've read, the product we received is fresh and not chunky.

Drastically reduced congestion
February 13, 2015
My cat has had cat herpes since he was a kitten. He is now 8 years old. I started using this product about a year ago and almost instantly received good results. He doesn't get snot all over the place as much as he used to because he doesn't sneeze as much due to less congestion. When I forget to give him these "treats" for a few days you can definitely tell. Best thing is, my cat loves them!

February 1, 2015
My cat has taken this product for 4 years so I have purchased this from you before as well as from other sellers. Your product is old and clumpy. I've purchased fresher product that was better in appearance and flavor according to my cat's reaction. I am very disappointed

Helps with herpes
January 27, 2015
Our cat Domingo has herpes in his eyes, causing excessive tearing. Our vet recommended these Lysine treats, which he loves. I only wish our other cat would also eat them. Bottom line, the herpes hasn't gone away, but it's much better.

A little clumped this time
January 25, 2015
I really like this treat. It helps my kitties who have Herpes Virus suppress the virus and control their symptoms. This particular bag was very clumped together and abnormal looking, but they usually are very good.

The Lady or the Tiger
January 20, 2015
My cat loves these treats but I never know which version of themselves they'll be (nor does my cat) when I open the bag. There's the moist, dark, sort of stinky nugget my cat likes best, or there's the dry hard blond scentless nugget he doesn't notice I've put in the bowl. When you open this bag of Ventoquinol you don't know what you'll get -- the lady or the tiger. Peculiarly inconsistent product.

Prescribed
January 16, 2015
This product was prescibed by my vet for my cats facial herpe. While she loves the products and eats them as if a treat, I have seen no improvment in her conditions whatsoever. I am now merely just ordering for her pleasure.

Different from before
December 1, 2014
I have been giving my cat these for years now. However when I opened the ones that I recently purchased, they were different in color and shape. When I contacted Entirely Pets, a nice young man named Michael checked with his Product Director; Nino and they assured me that the manufacturer had changed them and that they were good to use.

The lysine treats were different from the ones I received from my vet, despite being the exact same brand. They were much lighter in color, less moist, and looked "old"; surprising and somewhat disappointing. Cat still eats them, nonetheless.

Really helps!
August 23, 2014
My vet recommended this for a feral kitten I adopted when'd the antibiotics did not clear up his eye infection completely -- said it is a common herpes virus that may never clear up completely. These treats have cleared his eyes to the degree that there is only a very tiny bit of issue every 2-3 days that is really no problem at all. He absolutely loves them and comes running when he hears me shake them in the package. I give the recommended 6 per day -- 3 in the morning and 3 in the late afternoon. An added bonus is that his coat has gotten incredibly soft. They have been a great investment for me and I will continue to give them to him the rest of his life.

Effective aid for feline herpes
August 14, 2014
One of our three cats has herpes. This supplement is easy to administer: once a day I add 6 little pieces to her dry food OR to the top of wet food. I feed the cat from a separate bowl, so that I can see that she has eaten it. This has kept her herpes under control for several years now - there have been no flare ups, only a bit of tearing from one eye.
