    Easiest way to use L-Lysine by campgrandma from North Carolina11/12/2013

    My 2 cats love this Duralactin L-Lysine. It is so easy to use. They will even lick it right off the end of the syringe. Did I say they LOVE it! No problem getting it into them.

    good product by patchymoma from KY07/24/2012

    This was recommended by my vet for my cat with IBS. It has made a significant difference after using just a few days and my cat likes the taste and it's not difficult to give her. I found this on entirely pets website for a lot less than what I paid at the vet's.

    Great Product by Joey from Baltimore, MD05/29/2012

    My vet advised this product for my cat's respiratory & sinus issues. This product is amazing. My cat comes running & licks the gel off my fingers like it is candy. Also the price that Entirely Pets charges is great, so I am able to afford it. I have 4 cats, so I'm always looking for the best values. The biggest plus though is that my cat is no longer sneezing or coughing.

    great product by catmomma11/04/2012

    This product is great. It arrived promptly and best of all....it truly has helped my 9-year-old cat Camper. Thanks!!!! Will be ordering again.

    My cat loves this stuff! by Tara01/25/2012

    This makes it a lot easier to get l-lysine into my cat... he really likes the taste of it.

    Duralactin syringe by Kathy MacMaster08/23/2008

    My cat does really good with this product. It is easy to use and she has no recurring bouts of the herpes virus for several months now. I tried the canister that is available, but it was difficult to use. I highly recommend this product.

    by Vicki from Texas06/05/2013

    My 16 1/2 year old kitty loves this and it keeps her healthy.

    Works Wonders! by Jesslan01/18/2008

    My cats have been on Lysine for a well over a year now. They no longer get Upper Respiratory Infections as long as they're taking it! The minute I run out and don't have a chance to get some for a few days they start sneezing or coughing again and get sick. It's a real saver if you've got four cats and do everything you can to try to keep them from becoming ill and having to go to the veterinarian!

    Product recommended to us by our Vet. Seems to work very well, and we have used this for several years now to control this incurable virus.

    Product arrived quickly and not expired. Always worry about that.

    While visiting friends one day, I noticed that their two cats were ill with respiratory issues. I questioned whether they had been diagnosed with feline herpes since their illness seemed to relate to the symptoms caused by this devastating virus. Their cats were seen by the friends' vet, but it was too late for one of their two, so he eventually had to be euthanized after an attempt of saving him with antibiotics failed. I suggested to them that they immediately start their other cat on Duralactin. They wanted the paste type that could be applied to one of her paws for her to lick off, so I told them I knew of a great website where I could obtain this product for them. Their second cat has been healthy to this day, so I continue to order this product from Entirely Pets for her. It is such a convenience to qualify for free shipping and have it right at your door within a few days' time.

    Best Product Since Sliced Bread !!!! by Victoria09/17/2013

    This product is a literal life saver for my cat, Spats. Spats has ALWAYS been finicky and getting him to take supplements is like pulling teeth. When we adopted him we knew that he had herpes so I have tried to provide him with L-Lysine but the pills are huge and, even when turned to powder, not easy to mix into food without him knowing. Additionally, he is 11 years old and I have been trying to get him to take Omegas and Chondroitin to support his joints but, no luck. Then I found this product and it doesn't matter what time of day or what he's doing, if I present it to him he devours it like it's candy everytime!!! I urge everyone with a cat like Spats to try this. It really does work!!!

    Great product by Dale from Vancouver BC01/21/2015

    I am using this product to treat my cat that has a type of rhino virus.. Seems to be helping, as she has not had any nasal discharge since starting the product

    Lysine is the best medecine! by Val01 from Bucks county, Pa03/08/2014

    see attached video. Mayet, my kitty was recently diagnosed with upper respiratory problems. She also suffers from a yeast and bacterial infection on her nail bed since a couple of years. Until 3 weeks ago nothing cured the problem. Daily cleaning with medical pads, a laborious process, basically maintained her nail bed free of visible infection. A new vet prescribed steroid medication. That worked well However steroid can only be used temporarily. The vet suggested the use of Lysine to treat the upper respiratory symptoms. Mayet readily accepted the Lysine Syringe. 3 weeks later Mayet no longer sneezes precluding visible nasal discharges! Additionally I have yet to clean her nail bed in 3 weeks! We are thrilled with the result! We are impressed with entirelypets.com for carrying such a great product.

    lysine syringe by katlady from Fairless Hills,Pa10/28/2011

    Easy to administer for indoor pets.Great for preventive care.

    Works great for my "Miss Millie" cat by Mamarama01/02/2013

    Miss Millie has BAD peridontal issues and has a hard time with her food. Our vet recommended L-Lysine for her. Problem is that the pills are the size of Miss Millie,& there's no way to crush them without making a mess, so we decided to try this product. Millie actually waits, mewing to take her meds!! It so far is working great. Thank you!!
