Less Vet Visits with Enisyl-F
October 8, 2022
My order arrived packaged to survive and on time. I use Enisyl-F for my cats as a suppliment ever since their vet suggested I do so and they have benefited by not getting the sniffles like they were before. I add a pump to breakfast for the finiky one and the little one will lick it right off my finger. Will order again!

Merchant Response:Hello Patty, Thank you for your feedback! We love to hear you're seeing improvements.
Pros
  • My cats have been healthier since I have been using this - The one had the virus and would get bad sniffles 3 - 4 times a year and then give it to the others. None have had the bad sniffles since I started using the Enisyl-F. One of my cats LOVES the taste of it and thinks it is a treat.
Cons
  • One of my cats does not like the taste so I add it to wet food breakfast.

Helps With my Cat's Herpes Condition
September 9, 2020
This is a wonderful product in keeping my cat herpes in control! When I got her last year as a kitten she had herpes in her eyes. The eye problem is now a chronic condition. Enisyl-F helps keep her from getting recurrences with her Herpes! If I miss a dose she starts having symptoms. This really helps my sweet kitty!
Pros
  • Great Supplement For Immune System
Cons
  • My cat not crazy of the taste. They need to develop different flavors. It only has one flavor Tuna. Chicken flavor would be good as an alternative flavor.

It really works!
August 27, 2020
I used this stuff on my cats for years at the advice of my vet! They were on it regularly as a supplement and was told to increase dosage when I see signs of sniffles etc. It saved me so much money on meds and vet bills! Its worth it! Then my vet told me that the research done saying that Lysine helps pets is "unfounded" and does not recommend it so I stopped. My cats are in terrible health. It's been two years of drug after drug. Test after test. I've had enough. I will go back to enisyl! It's always worked! If it ain't broke, don't fix it!

Merchant Response:Hi Veronica, Glad you found Enisyl-F to work. Sorry it takes a little more $s to ship into Canada. Wish we could ship everyone for the same price. Take care!
Pros
  • Cats love it.
  • Cheaper and safer than pharmaceuticals.
Cons
  • A bit pricey. Have to order it online from the states (I am in Canada). After taxes, shipping and exchange, it's costly.

Helps my cat with runny nose
June 13, 2019
This was recommended by our vet to help with her sneezing and runny nose. We have noticed a great improvement since using.
Pros
  • Easy to use, we just squirt into her canned catfood.
Cons
  • No cons with product but all lysine products are super expensive.

Review for 3 Pack Enisyl-F Oral Paste for Cats - 300 mL

My cat has a chronic respiratory disease & requires this product. I am thankful that it is available & keeps him well.

Works Wonders
April 21, 2016
When I got my first hairless sphynx (6 years ago) she showed signs that something was wrong the day after we were on 14 hour drive back home and I wasn't turning around to take her back to the cattery (this was when we were 6 hours from home and coming home with a new sick cat was very depressing when I knew something was majorly wrong and I waited about 2 months to actually go pick the cat up) She was sneezing and coughing along with green gunk coming out of her eyes and nose. I took her to my regular small town vet the next morning after we got home and he thought she had feline herpes along with chlamydia and bordetella. He referenced me to a larger vet because he doesn't have all the high-tech tests, equipment, etc. and got my cat in the very next day. The larger vet thought that she just had an upper respiratory infection so we treated her for that with oral medicine. After repeated visits to the vet for 3 months of nothing working the vet finally suggested we do an expensive test to see what exactly was wrong with her and sure enough the test came back with everything that my small town vet had said he thought she had. She was put on a oral medication and an eye cream that was put together for her based on what came back on the test. She was also put on the Lysine pump to keep her immune system boosted and I have given this to her every single day since then. She has had 3 outbreaks since then and it was caused from pretty drastic changes: Got another hairless sphynx, moved into our new home (about 3 years ago) and we got a dog outside and she somehow must have sensed that someone else was being loved as well. During her outbreaks I gave her 2 pumps a day instead of just one and it helped a lot. She was back to normal in about 2 weeks. I also give the other cat the lysine pump as well because I was told that if one cat in the household has feline herpes the other one probably already contracted it. Overall this product is amazing considering how sick she was and what she is like now. I would recommend this product to anyone with cats who need that extra immune booster. It is also way cheaper on here than it is buying it directly from the vet.

Great Backup
April 13, 2016
My cats prefer the tasteless Felisyl granules that is mixed in with their food, but I keep a few of these Enisyl-F pump pastes handy to use for bad flare ups like diarrhea. Sometimes they aren't getting enough of the granules because they don't eat all of the wet food. This paste is the "powerhouse" and stops flare ups quickly. Also, I use it if they get hair stuck in their throat and start coughing - a little bit on my finger and into their mouth gets rid of the hair when they swallow. Great product and gets the job done.

Cats love it
November 24, 2015
Bought this for my cat with a runny eye that has the herpes virus. He loves it and it keeps his eye clear or very minimally runny. His brother loves it too, but I just give him a tiny taste as it's not an inexpensive item. Works like a charm and they love it.

ENISYL-F ORAL PASTE FOR CATS
October 13, 2015
I've been using this product for 5 years. This is a great product, my kitty loves the taste and I've seen a marked improvement in his health. He has feline herpes and used to get ulcers around his eyes, the ulcers used to get red and swollen and his eyes weeped, they still weep periodically, but the ulcers have gone away. I'll use this product until it is no longer needed and I hope my boy lives a long life!

After 2 or 3 visits to the cat eye specialist one of them recommended this product for both cats that we adopted from the SPCA. It's been about 3 years now that they get one dose a day and the eyes of both kitties are no longer weepy and runny.

It quiets the sneezing episodes
February 22, 2015
My 15? year-old male gets really bad sneezing episodes. He is a large kitty, so I give him more than the prescribed dose, at least twice the daily dose. It makes quite a difference in his sneezing attacks. I have used it for about 2 years, almost daily.

Easy to Give supplement
February 12, 2015
This product is a very easy to give supplement. The cats love the taste and will readily lap it up. It is most helpful to two of my kitties with the herpes virus. One is affected in her eye and the other in her sinuses. It certainly cuts down on the severity of the herpes flare ups. I highly recommend it. The only downside.... it is pricey.

Excellent for multiple symptoms
February 9, 2015
I started giving this product to my cats for periodic sneezing. I've since learned that the fish oil and l-lysine are excellent for kidney and arthritis issues as well. Most of my cats get this on their wet food but one doesn't eat anything but dry. I tried putting his on a spoon and now he waits on my desk every morning for his treat.

Cats with Feline Herpes - Must Have!
October 10, 2014
Vetoquinol Enisyl-F Oral Paste for Cats - 300 mL is the easiest measured method for administration of Lysine to cats that I have found. With a bit of effort you can actually place a precisely measured amount of Lysine in your cats mouth. If the cat is particularly ill this is the preferred method of administration . . . also can be placed on cat's paw and if not very ill a cat will innately attempt to clean it's paw (take the Meds on its own). This formulation of Lysine insures excellent absorption and Feline Herpes requires daily Lysine treatment if infected cats are to survive the illness!

Enisyl Oral Paste for Cates
September 6, 2014
I have been giving this to my cat, Myles, for nearly three years. It was recommended by the vet to address his probable Herpes; symptoms are sneezing, chronic upper respiratory "phlegm", and weepy eyes. He still has the symptoms, but they have been reduced, and he is far less likely to need antibiotics for an URI. So, not the "magic pill" but definitely contributes to better quality of life for him and less . And prices here are SERIOUSLY cheaper than those at the vet office.

Keeps Simon active
August 24, 2014
My vet had me give this to my cat, Simon, who has a chronic respiratory condition. I put it on a spoon and when I tap the spoon on the floor he comes running. So not only does he love it, I believe it keeps him healthy. He is VERY active. Entirely Pets has the lowest price that I've found for this product and they have extremely fast shipping at a reasonable cost. I'm happy and so is Simon.

Dessert for our kitties
May 22, 2014
Enisyl oral paste was recommended by our vet for our little part Siamese flame point Ginger. She was a shelter pet and had some issues with irritated bowel and upper respiratory problems. When this was first prescribed we tried to feed it to her like a pill but she would not swallow it. We decided to place it in a small dish beside her regular food and called it "dessert". She gobbled it up and our other cat also wanted a treat. Now they expect "dessert" every day after breakfast - we just call them and tell them dessert is ready and they appear. The paste has helped Ginger. She has not had any respiratory problems and only occasional small accidents from the irritated bowel. She's has been on her "dessert" diet for several years and she is now five years old.

Saved his life and mine
April 16, 2014
Our cat wandered into our life as a stray kitten and is now the light of my life. He came with upper respatory infection which took 5 months to clear, the vet recommending the Enisyl-F oral paste. I have kept him on this for nearly 3 years and he has remained symptom free. I have had 4-level fusions of both my back and neck and without Tonto beside me recovery would have been very difficult.

This product works!!!! Our adopted cat acquired Feline Herpes virus infection or Feline Viral Rhinotracheitis when he was a kitten before we got him. Several visits yearly to the vet was the normal routine until we discovered the Enisyl-F. Now the only time he sees the vet is for his annual check up and shots. Small price to pay for a happy cat!

Not sure if this is really it's intended use, but my Vet recommended this to help my cat's weeping eye. Bought the first bottle from him, seemed to help my cat, so I looked and found it on EntirelyPets at a much discounted price (awesome!). It's been more than 2 years and my cats eye has had NO issues. So for as long as she's with us, I will continue to use this product, and purchase it through EntirelyPets!

Feline Herpes

my vet recommended the lysine product as a supplement for my cats but it was quite expensive. I can purchase the same size, same brand for less than half what the vets office charged.
