Enisyl-F paste for cats
February 18, 2021
The paste works well, but the shipping time was ridiculous!! It took over a month to receive! I will no longer be ordering from Entirely Pets.

Enisyl-F for Cats
January 1, 2020
I have a Siamese that was constantly licking himself, to the point that his tummy was bald! He is a nervous cat (formally feral) and the Vet suggested that we put him on anti-anxiety medication. But I noticed that his skin and fur was dry. So I ordered the Enisyl-F oral paste and give him a large dollop both morning and night. His skin / fur is now soft and the hair on his tummy eventually grew back! So the product worked, but it is very pricey. I have 4 cats and all of them get the Enisyl-F, so it becomes very expensive.
  • Great for skin and hair.
  • Very pricey especially if you have 4 cats!

Excellent! Vet recommended for our 7 Persian cats. The paste is easier for me to make sure they get the correct dose. Easy to use and in the last couple of weeks, we have noticed they all seem healthier, especially the 4 older cats, and they seem more active and happier. I will absolutely continue with this product. Quick delivery and excellent service! I would definitely recommend it to my friends. --Meow, Meow, Meow, Meow, Meow, Meow, Meow !!!

We use this paste daily for our cat Shadow to keep her herpes virus in check. Entirely Pets has the best price for this product, so I always order from them.

Cats love it
September 9, 2015
My cats love the taste and demand their "treat". It has helped both of my male cats with their watery eyes and breathing issues. Well worth the price. It does have a strong fishy smell, which is what they like. My sister's cat HATES it, so get one tube to see how your pet reacts.

Great product for keeping feline ocular herpes at bay. Doesn't cure it but certainly keeps under control. Also wonderful for pilling cats - two of our four cats will lick it off my finger. The other two love it once it's put in their mouths.

needed medicine

Both my cats have feline herpes. This medicine was prescribed by vet and it was expensive. Buying it online has saved money as both cats must have this daily or they will get very sick and die.

It Really Works
March 1, 2015
Whiskers and Wags rescued a kitten about 7 years ago. She suffered from herpes in both eyes. Our vet recommended Enisyl-F Oral Paste. It took awhile but her eyes cleared up. She looks like a different cat. She gets her pre-measured dosage once a day. We have ordered Enisyl-F many times and will continue to do so. If you have a cat that suffers from herpes, you should try Enisyl-F Oral Paste.

Nicest Product
February 18, 2015
Enysil-F was recommended by a Vet. I use it on top of my cats food every day. They both had conjuncivitis as kittens but are both conjunctivits free right now. I continue to buy Enisyl-F from Entirely Pets. The package comes in the mail so quickly. Thank you for the great service.

cats -general health booster
July 21, 2014
Cats, especially kittens love it. I use it for a general immune booster or to help a cat get over an illness. Also to stimulate appetite. Has a slight oily/fishy smell if you get really close to it which explains why cats generally like it. I have 6 cats so muchoo experience.

I have two kitties that carry the herpes virus. This is the easiest way to give them lysine. They love the taste,( I actually have a couple others who do not need it but love the taste as well). I highly recommend this product. I have been using it for 5 years now.

My two cats both have a virus in their gums. Enisyl-F was recommended by our vet to keep the virus under control. They love it mixed with just a dab of canned cat food.

Excellant product, kitty loves it!
March 3, 2014
My cat was diagnosed with herpes (weepy eye) and the vet had me give him Enisyl-F paste 2x a day. This took care of the problem and he loves the taste so no issue in giving it to him. The vet charged me $40 per can and since I used 1 can every 5-6 weeks it became a little expensive. I now buy the 6 packs of this product and what a savings! Very happy my kitty no longer suffers with itchy eye and the cost is way down too!

Review for 6 Packs Enisyl-F Oral Paste for Cats - 600 mL
September 28, 2013
I use several Lysine products for my cats. This one they seem to like the best. The pump is nice too in comparison to squeezing out the tube. I also haven't found this any cheaper than at entirely pets.

L-lysine paste the best ever!
August 27, 2013
Four years ago I found this site and ordered the L-lysine paste (6pack) for my Persians. They would not accept any other form of this product. Both of my males love it and both females accept it. Only suggestion would be to offer syringes to fit into the opening to draw out the product. I have to ask the Vet to give me some every 6 months or so. I have introduced this product to two other cat owners who are very satisfied. Shipping is always fast, accurate, and I appreciate the free shipping when I order the amount necessary to receive it. Thanks again, Mary

July 23, 2013
Since using this, my cats have not have any herpes breakouts. I am happy knowing that they are getting nutrition and help needed to eliminate (so far) any breakouts. I will continue ordering from Entirely Pets. They are extremely fast in shipping and so efficient. I thank them so much for that.

Really Works!
May 27, 2013
Jorge, our 3-year-old, mixed breed cat, came to us as a stray a couple years ago. He had a runny nose and watery eyes. We took him to our vet, who checked him over and gave him vaccinations. The doctor said he had a chronic upper respiratory viral infection known as "Rhinotracheitis". (Herpes) Doctor recommended Enisyl-F Oral Paste for Cats. It doesn't cure it, but one dose a day mixed in soft food keeps his symptoms to a minimum. One dose in the am and one in the pm would probably help more. We often have flare ups in spring and fall, but 1 dose a day helps a lot!

Seems to have helped 2 cats with chronic eye drainage. It is subjective but it seems to have decreased in frequency and amount. Two tubes have malfunctioned and I can not use them. One cat eats it eagerly the other likes it OK

Great product and amazing value
May 14, 2013
I used to buy the human pills and crush them. This product is normally over $50 each in Australia and this bulk pack gave an excellent value to an already worthwhile product. Pre-measured and palatable. Some of my cats will even just lick the paste. Well done Entirely Pets, this was my first order with you and I have already ordered my second lot of products from you.

Has been very effective
May 7, 2013
This has worked very well with my elderly rescue cats, 2 of whom have feline herpes. I have used this daily for about 2 years now and believe it has helped cut down on trips to the vet. First recommended by my vet, but a much better price through you.

My cat needs this
May 1, 2013
This product has made a huge difference in the health of my beloved cat. He had feline herpes as a kitten before I got him. We had many infections requiring vet visits and antibiotics before I began daily use of the Enisyl-F. Now his watery eyes and nose are in much better shape and no infections. He is a terribly fussy eater so he has to be given this orally by syringe. My son's cat loves it (he has somewhat the same health problem) and eats it off a spoon.

Very good product
April 15, 2013
My cat has the feline version of HIV and this product was recommended to be by a vet after my cat became very sick. He gets the paste twice a day on top of treats. He loves the paste (I know because he looks for it on the treats). He has not been sick once since he started eating it. I can't tell you for sure that it was a cure all, but I know he is thriving, so there is no way I would stop giving it to him. By the way, Entirely Pets has the best price anywhere for this product so thank you to them!

Best Med for feline herpes at a much better Price!
April 10, 2013
My cat Kali is a rescue cat. When I got her, my vet told me she had feline herpes, and would need constant medication to maintain her health. The vet prescribed Enisyl-F Oral Paste and I was paying $30.00 per tube at his clinic! I found Entirely Pets on line and they have the same medicines that my Vet prescribed at a considerable savings! Thanks to Entirely Pets, I can better afford to take proper care of my sweet kitties' problems and keep her herpes under control so that she can live a normal and happy life.

Everything I've ever ordered from Entirely Pets has been on time and in great condition. I have 2 cats that have eye conditions and this was a product recommended by my vet - not something easy to find though. I was happy to find it here and we use it daily. The cats like the taste and I like the ease of ordering through Entirely Pets.

Enisyl-F works!
February 19, 2013
Our cat, Franz,(10 years old) had a bad episode of Herpes in his mouth at about age 6, and wouldn't eat due to the blisters or pain from swallowing. We had him in the hospital until the symptoms subsided, and ever since, we have given him the Enisyl-F in his food twice a day, and he has never had a relapse since then. It really seems to do the trick. Very convenient to order online and competitive pricing in the 6 pack!

This L-lysine is so easy. I have cats that will eat it off my finger. If not, squirt it into a syringe and feed it that way. Nozzle fits right in most 1 Ml syringes.

Since my cat is older, i have to give him lysine to help his immune system. He gets a few pumps a day to keep his upper respiratory in check. And its so much cheaper then at the vets office or amazon. Thanks again. Shirley

Great purchase
October 30, 2012
I received the product within 1 week..very fast service. This is a great product if your cat has upper respiratory virus. It stopped my cat's runny nose after a week of giving 4 pumps per day. It takes time to kick in so be patient. My cat has a pretty sever flare up right now so I am going to have to take him to the vet this time but it works well when the flare up is not severe. The only reason I took off 1 star is because it doesn't work so well with severe flare ups.

Enisyl F, recommended by my vet and first purchased at the vet office, has helped keep the symptoms of feline herpes to a minimum for my cat. And on line multi-pack purchasing has cut the price about 40%.

An Extra Treat

I have a little guy who has a bad case of feline viral herpes. This stuff is an answer to a prayer and gives him a fighting chance to have a good life. He thinks it's a treat and comes running the moment he hears the lid pop. I wish all medicine was this easy to give and worked so well!!!!

Enisyl-F Paste saves the day, every day!
November 15, 2011
We have a rescue cat named Kali. When we first got her, we took her to our vet and he prescribed Enisyl-F for her at $30.00 a tube! I paid it for a while until I did a search on line and found the same product available at EntirelyPets for much much less! I order it in large quantities at a time which saves even more. More importantly, it really works to help us keep Kali's feline herpes under control. We throw in some of the Enisyl-F treats for her every day too, she loves to chase them and gobble them down. I never have a problem getting her to take her medicine, and we are very very happy that our kitty stays healthy with the Enisyl-F products.

an easy way to medicate
October 27, 2011
Getting the correct dose in my cat is crucial. The pump makes it accurate and easy. I used to try to add lysine capsules to vitamin paste, but it required so much to mix the powder, my cat would never finish it all. These are portable, clean and best of all, my cat thinks it's a treat!
