Lysine Aid Cat Gel

L-Lysine Supplement for the management of Feline Herpes (FHV-1) in kittens and cats has been shown to inhibit replication of the Feline Herpes Virus (FHV-1) and can be used in the management of FHV-1 infection.

Feline rhinotracheitis virus (feline herpesvirus type 1 or FHV-1) causes acute respiratory illness known as rhinotracheitis (or feline herpesvirus infection) with the virus affecting domestic and wild cats worldwide of 50% of household cats. 

Cats of all ages and breeds are susceptible although it is more common in the following: Kittens especially those born to infected mothers,  Multi-cat households catteries, pet adoption shelters especially those with: Overcrowding / Physical (e.g. temperature) or psychological (e.g. introduction of a new cat) stressors /  Poor nutrition / Poor sanitation and Poor ventilation / Pregnant cats that are lactating / Sick cats (especially sickness associated with a weakened immune system or other respiratory infection)  and Unvaccinated cats.

 Management Vaccinations are available for these viruses.

Feedback for Lysine Aid Cat Gel has been compiled from 16 customer reviews


I can't ask my kitten what he thinks, and although it said on the bottle, 'it's palatable', he wasn't too keen on the taste at all.
but when mixed through his first small batch of food in the morning, he does eat it and it has seemed to make him calmer.
I was adviced to get this lysine gel by my vet to help to combat cat flu virus, and 2 weeks on.. I can say it looks like we did ;-)


It's the only thing that helps with my 18 year old cat who has a stuffy nose that bleeds on and off after a bad dose of cat flu 18 months ago. Even a CT scan can find nothing wrong.


Not sure whether there has been any improvement as yet


Early days but seen an improvement in both our kittens




very good product will buy more and recommend it to friends


Lysine added to food as directed. Used over approximately 3 days. First meals she ate as normal, the second hardly ate any and went to her kibbles. It seemed to have had an adverse effect as Hollie refused to eat at all and was just drinking water. She has been very lethargic and had a continuous 'snotty' nose. I've further researched Lysine via ehow website and it does state that it can cause further problems. Obviously I no longer use it and it's back to the drawing-board and as well as a visit to my vets, further research is required. I confirm that this is no fault of your Organisation, if anything it's mine, I just want the best for her and will endeavour to find a solution to her condition. She still can't as yet, have her yearly injection due to having had cat flu as a kitten. Could any of your vets give me any advice please?

Thank you for your prompt response. If you can advise further it would be greatly appreciated. Are there any food supplements available that would be beneficial perhaps?

Great product, helps clear up cats runny eyes and sneezing.


I give this to my cats as a supplement to enhance their immune system - it works well.
