Great for Allergies!
July 31, 2014
My vet recommended this product because all of the sudden my cat's one eye was tearing up all the time and oozing plus she would get a droopy eyelid. I gave her the recommended double dose the first couple of days then backed down to the daily dose and her symptoms cleared up within two days. There are times when I forget to give her the treats (because I have another cat that has stomach issues and cannot have the treats and she knows when they are out) so within a day or two you can start to see the symptoms return. Once I start giving her the treats again it completely goes away. I would highly recommend this product for allergy issues.

Really great

My cat has a thyroid problem and is on medication twice daily. This has affected her immune system, and the vet recommended the lysine treats. I give her four each morning, which she likes, and it seems to stabilize and help her immune system.

My 3 cats love these treats.
May 2, 2014
My vet recommended these treats for one of my cats as she had ragged breathing. They cleared her right up. And she said all of my cats could eat them if they liked. I give them to all 3 from time to time. I think they keep them healthier.

Seem to be OK
April 23, 2014
These are accepted OK, not great, but OK. The one thing to note is that, if left out, as in if she dosn't eat them all right away, they get hard. Once hard, my cat rejects them. You have to give 6 - 12 pieces a day but they are small so that is OK.

Ensisyl-F Lysine Treats
April 7, 2014
My cat, Star has feline herpes and at her current age (13yrs) she has flare ups that cause sneezing and coughing. My local vet recommended this supplement and I started about five months ago. It works. Her health has improved ( no more sneezing and coughing) and she's gained weight and strength.

Good value, about 250pcs. in bag.

Both of our cats had this product suggested to us by our Vet. The Vet charges about 30% more for the identical package. I try to feed one to each cat about six times daily.Usually the cats just smell the little ball of product and down them without any problem. It seems like lately the cats will walk away from the product and I have to force feed. They don't seem to mind the forced feeding, but then cats are at best . . . strange. I do not have to use much effort when forced feeding. I would never do anyt6hing to harm my cats.

L-Lysine Treats a Hit with Tawny
March 28, 2014
My orange and white Tabby cat Tawny was born with feline herpes virus. It causes outbreaks of nasal congestion, sneezing and occasional fluid in one eye. The L-Lysine treats are a big help in suppressing the virus. There is no permanent cure but it can be controlled and the treats are a big part of that. He loves them and eagerly eats as many as 12 in one day when symptoms flare up. I recommend the L-Lysine treats because you can easily vary the dose. If you have other cats, as I do, you can give them ordinary treats when you give your other cat the L-Lysine treats so they won't feel left out!

Sickly cat will eat them!
March 5, 2014
I bought a bag each of 3 kinds of lysine treats, hoping that my sickly cat would willing eat one of them, and this is the one that he liked. When his appetite was low, I could often coax him to start eating by putting these in his bowl. The form changed several month ago to a smaller kibble, and he still will eat it, though not quite as eagerly.

Both of my cats used to have herpes breakouts occasionally. I originally used the powder version of Enisyl mixed in with wet food, but they didn't always eat it all. They both went crazy for these treats when I tried them and they don't have kitty colds or conjunctivitis any more.

Enisyl-F Lysine Treats
February 22, 2014
Our two cats love them. They wait every morning for the treats. I give them six and if they start sneezing I give them more in the evening and it really helps them get over the sickness quickly. Sometimes they actually stop sneezing within a day or so. I will never be without them and they are a little cheaper getting them from Entirely pets than at the vet.

I have two cats with weepy eyes. This treat helps greatly, and they like it. It does dry out too fast, even though I always seal the bag tightly. And occasionally, I get a bag that has a lot of small crumbles.

My cat Lily eats her daily lysine treats first thing in the morning, mixed with a few of her favorite treats. No problem giving her the added protection that lysine offers cats from upper respiratory infections. She likes them!

Great for cat health!
December 16, 2013
We use these for both our inside and especially our outside feral cats. We have seen the outside cats eyes brighten, skin/fur look better and they have overall been much healthier. Seems silly, but we really attribute this to the ongoing use of Lysine. And...yes, these are more expensive than some of the other Lysine products, but ALL of our cats love them, think they are treats and readily eat them. We highly recommend these!

Enisy-F Lysine Treats (6.35oz)
December 1, 2013
Our vet recommended this product to aid our cats immune system. We give him 4 treats 3 times a day. In order to get our cat to eat these treats we started by giving him just 2 treats at a time while holding his regular cat treat bag. After several attempts with him getting no treats for the day he now takes his Lysine eagerly (looking forward to his other anticipated treats - which of course he gets) Product is competitively priced - We save cost by purchasing the quantity that provides free shipping.

Lucy and Milo love these treats. They were a very good deal online so I bought 2 bags. This helps them from sneezing so much and was recommended by our vet. All good!

Has done a good job keeping Buddy's eye discharge in control. However, do not buy to much at a time as the product does seem to get hard and lose it's smell . We store it in a plastic jar with screw -on lid, after we open the original bag. After it begins to dry out Buddy will not eat it.

This is a great way to give your cat L-ysine if you have to give this daily.My 6 month old kitten loves them and they're easy to give as a treat. It saves me from having to crush Lysine to put in his food all the time!

Cat likes this product better than another brand which is hard to chew and has difficulty swallowing. This brand is soft and is very like other cat treats and don't have to force cat to take.

My cat ate a couple then wouldn't touch them after that. I prefer the formula that comes in a pump....much easier to give to my cat.

September 22, 2013
Bought these as Lysine was recommended for my cats sneezing, and he wont eat the lysine medicine you can put in their food. At first he wouldn't eat them but mixed them with some other treats so now he eats them fine. Seems to help the sneeze a bit, so will continue to use.

An essential part of our cats' diet
September 18, 2013
Some years ago, when our previous 'generation' of cats were quite old, a friend veterinarian (feline specialist) told me that L-lysine 'worked' to inhibit and control a number of problems. She admitted that, at the time, it wasn't known exactly 'how & why' this amino acid supplement worked, only that it 'did' work. Given her reputation and knowledge of cats, I totally trusted her and began seeking out a viable way to give L-lysine to our cats. Without going into all the difficult ways, I can only relate that we were fortunate enough to try convention 'samples' of Enisyl-F before it hit most sales outlets. From that time on our cats have 6 pieces every morning and devour them like treats. The fact that Enisyl-F may minimize flare-up of herpes is a significant bonus, especially with eye-related issues. This is a fine product and an essential part of each day for our 4 year old guys since they were kittens.

I use this product, because my calico contracted feline herpes as a kitten. This product not only helps boost her immune system effectively, I also don't have to "force" her to eat it. She loves the taste. It has a pungent tuna smell, that appeals to cats.

These are really good. My one cat has a little trouble getting them in well all the time, but these help them a lot when they start to get sneezy or seem like they might be getting a cold or something. The size of the treats vary sometimes - it hasn't been a problem but in case anyone else wonders if that's normal! :)

Enisyl-F Lysine Treats
June 17, 2013
When we brought out kitten home from the county animal service she had sneezing fits. The vet thought it could be a "kennel cough" or allergies and recommended Enisyl-F Lysine.. We have had her on this for 1 1/2 years and her sneezes have gone away. She thinks the Lysine is a treat and continues to get it daily.

Best treat ever

I ordered Enisyl-F Lysine Treats together with the L-Lysine powder. When I shake the bag, everybody comes running, sitting patiently in a half circle awaiting their part. They like the smell and the soft chew.

Great lysine treat

My vet recommended this treat and I had to buy it from the vet at the time at a higher price and whenever they stocked it. Entirely Pets has it at a good price and at any time and they ship so fast. Great company to buy from.

Enisyl-F Lysine Treats have really helped my cat's feline herpes eye infection. I recommend it to anyone whose cat has this problem. My cat came from the shelter as a kitten with his eye already bad. It got terrible, and a new vet recommended this product. I am glad she did!!!

Keeping feline herpes in check
April 18, 2013
We've been using this product since we adopted our cat as a young kitten. We adopted the kitten from a veterinarian friend who told us of the chronic herpes eye infection the kitten was born with; he recommended this type of product. Although the condition is incurable, the addition of these treats to "Bella's" daily diet seems to keep the condition in check and the cat loves them.

This is probably the sixth bag we've used with the first being from the vet which was more expensive. None of our cats have turned up their noses at the treats and they always disappear even with our toothless cat.

My cat's chase and kill "treat"
April 10, 2013
I use these treats for upping the coverage of lysine for my cat Kali. I throw them one by one down the hall for her to chase and devour. She loves them, and it's an easy way for me to get extra lysine into her when her herpes is flairing up too much. I'm thankful that there are easy ways for me to get medicine into my cat rather than holding her down and forcing something down her throat every day!

Great product - vet prescribed

I like this product, what it does and how well it works. But my fussy little persian gets tired of it and they are a bit hard for her to chew. So I switch to Optixcare L-Lysine for Cats, when she gets tired of it. Or try the paste as another way.
