It wasn’t too long after Lily was diagnosed with stomatitis that someone recommended that I start giving her Lysine. I have been giving it to her ever since and have seen what happens if I stop giving it to her.
Lysine for cats is similar to Vitamin C for humans. It is an amino acid that helps boost the immune system. I’m sure there are far more technical descriptions about lysine and cats, but that is the extent of my knowledge. This is the same thing as L-Lysine that humans take, but the one for cats includes flavoring to make it more palatable for them.
When I first heard about Lysine I talked to my vet about it. I didn’t want to give something to Lily that might harm her. According to my vet, Lysine is safe for cats and has no harmful side effects.
There are a lot of different Lysines on the market, but the one I give to Lily (and all of my cats) is called Vetoquinol Viralys Powder. As I said above, I started giving it to her within a month or two of her being diagnosed with stomatitis. It helped, though I admit that it wasn’t enough to “cure” the inflammation in her mouth. But, it did help lessen the pain and redness.
I wasn’t sure exactly how helpful Lysine was to Lily but I did know that she no longer drooled while on it. Then came a day when I ran out. I had ordered more before running out but the seller accidentally sent the wrong item. Lily went without Lysine for a week while I waited for the Lysine to arrive. During that week her stomatitis got worse to the point where she was drooling again. The drool was tinged with blood and I knew she was in terrible pain. Never again will I let Lily go without the Lysine.
Today Lily is still on Lysine, as well as PlaqueOff and a steroid cream. You can read my review of PlaqueOff here, and see how I give the Lysine and PlaqueOff to Lily here.
Lysine for Cats
I buy my Lysine from Amazon. The prices are low and free shipping is offered. Initially I bought it in a small container (100g). About six months later I discovered that it also comes in a much larger container (600g) and now I buy that one. It is more cost effective to buy the larger container, especially now that I’m giving it to all five of my cats every day. I keep the small container to use daily and fill it with Lysine from the big container as needed.
Here is a picture of the two different sizes so you can get an idea of how large they each are.
The small container lasted for several months when I gave it to just Lily, but ran out quickly after I started giving to our other four cats. The large container has lasted for almost a year and cost much less per gram than the smaller container.
The Lysine that I buy is from Viralys (seen above) and comes with a dosage spoon so you don’t have to figure out the dose yourself. The daily recommended dose is about 500mg.
