Is this good for feline herpes?
Answer by ChewyNov 22, 2018
L-lysine is often used to help with various ailments, including viral infections and feline herpes virus. L-lysine has been shown to reduce the severity and the duration of the feline herpes virus. It halts the replication of the virus by interfering with another amino acid called arginine, which the virus needs in order to replicate.

waste of money

When I received this for my cat I was impressed with the packaging and 'delivery system'. The first two uses were fine...the PASTE wasn't liked by the cat but he tolerated it. Third dose delivered a separated product with an orange oily substance and a thin paste both squeezing out. The packaging allows no way to re-mix the product and my cat wouldn't go near the runny oil-like product. Waste of money.

Small container

My cat absolutely LOVES this stuff! Problem is that it is so pricey and the container runs out very quickly. I swear he would joyfully lap up this whole tube in one sitting if I let him.

Finally! A Way My Cat Will Take Her Meds!

My cat is one of those who absolutely refuses to take medicine of any kind in any way, shape, or form. I've tried crushing pills and putting liquid in food, hiding it in treats and pill pockets. I refuse to force feed the meds due to her having been a feral before we rescued her, and I will not break the trust that I have worked so hard to gain over 3 years. I was at wit's end when I ran across the Duralactin L-lysine supplement in paste form. Because she loves to be fed chicken and tuna by hand, I was able to trick her into thinking the Duralactin paste I put on my finger was a treat, too. It must taste rather good, too, because she licks it right off without hesitation. I am thrilled to have found this and wish there were other medications just like it!

My cat loves it!

I highly recommend this if your cat is as fussy as mine- not only does he love the paste, he has significantly fewer upper respiratory issues so no more monthly vet visits. And for those people complaining about the expiration date, DOM means date of manufacturing, NOT expiration date

Helpful for our kitty's calicivirus

Both our kittens have been sick with feline calicivirus since we adopted them, despite getting vaccinated. The vet recommended this to help with inflammation along with antibiotics, and its really helped them. They love the taste (which we mix into wet food), and the vet said we can give this supplement to them indefinitely without consequences should they become lifelong carriers. The syringe & measurements on the plunger are really helpful for proper dosage amounts, but I only gave 4 stars because we wish it came in a more eco-friendly dispenser.

Date is not Expiration

I see a lot of people on here saying that there stuff is expired! If you look it says DOM. It mean Date Of Manufacturing! It’s not an expiration date! If it says 06/2021 it’s just when it was made. So don’t waste your money and throw it away. It is still good!!! :)

Our kitten couldn’t breathe through her nose when we got her. She was sneezing, coughing and her eyes were watery. We tried this, and it really seemed to help! A week after we ran out of this, her eye started watering and she started sneezing again. I think we need to buy more Maybe five more—

This has been helpful!

I have an FIV positive cat; fortunately so far he only shows some skin problems. The Lysine has really helped. I am very pleased!

Lysine Supplement

I acquired 2 sick kitties with upper respiratory infections and was given a recommendation from a vet to use this supplement. I noticed a difference in my kitties after the second day. They don't like it, but it really helps with their immune system.

It takes time to work

I bought this for my cat that has chronic sinus issues that don't go away. She ends up at the vet 2 to 3 times a year for antibiotics due to the issue turning into infections. The vet stated to give her lysine but I could not find any treats she would eat so I thought I'd try this. She absolutely won't take it on her own but I figured out a way to give it to her. I took a 3ml syringe, remove the plunger, fill in the dose, put the plunger back in and then squirt the gel into her mouth. She doesn't like it but she needs it. You do need to allow time for it to start working though. You may need 2 to 3 full tubes before you see effects since it is a natural remedy and natural remedies take time. She now sneezes less often and is quite a bit less congested.
