    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.
    • 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.
    • 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!
    • Great Supplement For Immune System
    • 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!
    • Cats love it.
    • Cheaper and safer than pharmaceuticals.
    • 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.
    • Easy to use, we just squirt into her canned catfood.
    • No cons with product but all lysine products are super expensive.

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

    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.

    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!

    Enisyl-F Oral Paste is my cats' favorite treat! They love the taste. I love how it reduces flare-ups of the herpes virus they contracted before we rescued them. It's great stuff. Just ask the cats!!

    June 27, 2015
    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.

    My cat liked the first can and then did not want it anymore so I had to force feed it to him. Going to the treats for awhile. Then he will like the can again. Its a cat thing.

    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.
