    Efficient service by schmee's mom from Washington, DC10/19/2011

    I order Enisyl-F on a regular basis for my kitty, and my order arrived quickly and in good condition.

    excellent product by yokokam from Hong Kong12/15/2013

    I must say this is an excellent product for cat, especially for Exotic , will keep feeing them !

    Great purchase by love cats10/30/2012

    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.

    by Sue from Fort Wayne, IN10/23/2012

    Product was delivered quickly. It definitely helps my cat with her breathing issues.

    Has been very effective by Jodi05/07/2013

    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.

    A Must For My Cats by Cricket & Weasel's Mom from Woodstock07/02/2013

    Both my cats like this form of Lysine and they must have it for their health. We use the powder and the treats too. Great product and the price is usually good at Entirely Pets.

    Enisyl-F Paste saves the day, every day! by Kali's Mom11/15/2011

    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.

    Very good product by Latka B from Los Angeles04/15/2013

    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!

    we love it by carmen cakes from Fremont, Michigan12/13/2012

    this product works better than any others we have tried. And best of all the cats love the taste.

    This is a great medication for cats with herpes virus.

    Excellent by kt20127 from Westwood, NJ07/28/2014

    I love this product. It keeps my cat healthy. It helps manage his allergies - he no longer coughs or sneezes daily and his eye mucus has subsided. Highly recommend.

    Enishy-F Oral Paste for cats by Sara from MI03/29/2012

    Easy to dispense. Cat likes flavor and laps it up. Excellent way to administer lisene according to the vet's orders.

    My cat needs this by cag from Plymouth, MA05/01/2013

    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.

    Amazing results by Peter from New Port Richey Fl07/18/2012

    I have an aids kitty that is always drooling with bad breath. This product over a month period has made the problem almost disapear.

    Enisyl-F works! by Franz's mom from Fairfax, Virginia02/19/2013

    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!

    Good product, great service by angela from Michigan03/24/2013

    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.

    An Extra Treat by freehawk from Phoenix, AZ05/29/2012

    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!!!!

    Best product for kitties immune system! by Grannybrenda11/07/2012

    I am very satisfied with my purchase of the Enisyl-F oral paste for cats. Our cats all love it and it is so good for their immune systems! The order was complete and arrived quickly!

    Best Med for feline herpes at a much better Price! by Kali's Mom04/10/2013

    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.

    Works for my cats by Susanna from Toronto, Ontario CANADA01/17/2014

    I have been very pleased with this product which was recommended by my cats vet. They both like the flavour. I did request some assistance in opening the packs though but have not heard back from anyone. Sometimes I find okay but the last one I had to break and was left with a tube that have to squeeze to get the product out which is not the best. Please direct me on how to open properly. Regards, Susan

    by from 09/28/2013

    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.

    Enisyl-F Oral Paste by Tobius from Elliot Lake, Ontario09/17/2013

    Works great, the cat has stopped sneezing and seems to just be better. Great Stuff.

    Enisyl-F paste by Teri from Tucson, AZ07/13/2014

    This product truly helps my cat with breathing and sneezing issues. I get a great price and quick delivery from Entirely Pets.

    Wow! by Sawbones from Middleton, WI11/04/2012

    Our feline,Danny, has been dancing to rock and roll music on the stereo and performing backward flips ever since we started giving him Ensyl-F. Thank you so much.

    Great Product! by purrs from Merritt Island, Fl06/06/2014

    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.

    cats -general health booster by Story from Southampton,PA07/21/2014

    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.

    Love it by jmr2 from San Diego, CA01/20/2013

    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.

    This stuff made a difference by Aggie& CodysMom06/23/2014

    Without Enisyl my Aggie was a projectile sneezer, and an unhappy kitty, life is so much better now

    Great product. Great price. by Jo07/17/2012

    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%.

    Enysil-L by aquamansergio02/04/2014

    Fantastic product to boost your cat immune system and protect them from Rino.....which 85 % of cats have........

    I ordered a 6 Pack of Enisyl-F Oral Paste for Cats - 600 mL. Price was competitive, delivery was very prompt and follow up superb. I will continue to order from EntirelyPets.

    Excellant product, kitty loves it! by Kikikobe from Huntington Beach, CA03/03/2014

    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!

    by Sue02/01/2012

    Delivered in a very timely manner and met my expectations.

    Really Works! by Angie E from North Dakota05/27/2013

    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!

    by from 05/27/2013

    Seems to have helped 2 cats with chronic eye drainage. It is subjective but it seems to have decreased in frequency and amount.

    Great product and amazing value by Gingernutta from New Beith, Australia05/14/2013

    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.

    an easy way to medicate by justy from PA10/27/2011

    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!

    by from 05/17/2013


    My vet's office now charges $35 each for these! My cat LOVES it!!

    Enisyl-F for Cats Review by iluvcats from Louisiana07/23/2013

    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.

    Cats love it by Richbeast from Iowa05/09/2014

    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.

    by from 01/16/2013

    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.
