We use this for cats in our shelter. It's mixed into their canned food daily. Much more economical than l-lysine marketed specifically for cats.

From what I have read, it is the number one most likely deficient amino acid in your horse. It doesn't cost that much per serving. Product has always been consistent.

Something to Boost your Pets Immune System
September 15, 2014
I've been giving Lysine to my cats & dog for over two years. Recommended by a friend who runs a cat sanctuary I tried it. Have found that my cats seem to be healthier & less susceptible to eye, allergy & skin problems. For a healthy pet I would strongly recommend you provide this important immune booster to them.

Much more cost effective than l-lysine specially made for cats. I'm mixing this into canned food and it doesn't seem to affect the taste.

Lysine is one of the 20 amino acids essential to horses, but often is the most deficient in their diets due to its inadequate levels in commonly-fed cereal grains. Amino acids are the building blocks of protein, which form muscle, enzymes, and hormones throughout the body. Horses can only use them if all essential amino acids are present at sufficient levels. A plus with this item is it helps muscle development. I use this as alternative to numerous shots. Purchasing through Entirely Pets saved me money.

Lysine Important for 56 Rescue Cats & Dog
December 19, 2012
I have been buying Lysine for about 15 years now for my Rescue Cats & Dogs. I use it every day on their food. When I took in 15 kittens 2 years ago they came with FIP and the one thing the vet kept saying is make sure they have lots of Lysine. I kept telling her I buy it by the 4lb bucket and use it daily. We saved 13 of the 15 kittens.
Yes I recommend it very highly. Laurie

Ordered Pure Lysine due to a hoof issue. Vita flex has always made good products. Only issue I had was the length of time it took for product to arrive

I run a cattery and the cats absolutely love the taste. I don't use as much of the l-lysine for horses as I would of the cat l-lysine. Thats also a good thing less l-lysine but the same effects. The taste is apparently very appealling to the cats as they ate it like it was the best stuff around.
