What is the age limit? Youngest?
Answer by ChewyJul 14, 2022
It is always best to check with your veterinarian who knows your pet's medical history, age and size. Without knowing the age of your pet it is difficult to say. L-lysine can be given in much smaller doses for kittens under the age of 6 months. You should start out very small and gradually increase to about one half scoop. If the cat shows any discomfort, the dose could be too high.

Don’t hesitate!

This Lysine powder is great. I’ve tried different chews but my cats wanted no part of them. This powder mixes in well with wet food and my cats clean their bowls. Give it a try and I think you and your kitties will be happy!

Great product

I have two Persian cats. I used to give them vetri science lysine chews and they loved it. Then they changed their formula, it smelled weird and they were rock hard. I tried re purchasing a bunch of times because my prior experience with lysine powder wasn’t good. Every order of the chews was awful, so i had to hunt for something new. Even Tried the gels. My cats wouldn’t even go near it. One of my kitties developed a sequestrum in his eye and had to have surgery. After almost 2 months and a million drops a day, the vet said his eye was healing unusually slow. He was not on a lysine supplement during this time as I hadn’t found a good one they liked. Well, i finally found this, and almost immediately his eye started showing real improvement! I didnt do anything else differently except add a scoop of this to his food twice a day. Hes almost all better now, and i really do think adding this helped. Also, the cats seem to like the taste too.

Mixes Well!

My girl was diagnised with feline herpes a few years ago and I have since tried lysine treats and gel which she did not love. This powder mixes well into her wet food and she does not seem to notice it in there! Bonus points that it comes in salmon flavor which she LOVES. Mine did not come with a scoop but I just add a spoonful.

My cats love it & it works!

when the Temp outside drops to about 40 degrees I start putting 1 scoop of this L-Lysine powder per cat into the canned cat food I fix for my colony cats, mix it well in a large plastic bowl with lid, they all love it & it works for cold symptoms!

L-Lysine powder

My cat is quite finicky, so I am using only small amounts in food that I think he likes enough to finish. Too early to tell if it will help his issue, but I think it blends well in wet food. The scoop is in the jar, but I just put a bit in a teaspoon, since a whole scoop would seem too much for the amount he eats at once. The powder sort of sticks together, making it hard to shake out only a little at a time. But putting the amount into another spoon works fine.

Miracle product

The lysine powder is amazing! I have a couple cats with respiratory issues and within a week they were snot free. I mix it in their canned food and they eat it right up. Highly recommend.
