Questions & Answers

Will this also help with bad dandruff?
Answer by ChewyFeb 10, 2022
Lysine Immune Health+ does not help with dandruff since it helps support immune health, skin and eye health, and allergy symptoms such as congestion, sneezing, wheezing, itching, squinting, and eye and nose discharge.

Are any of the ingredients sourced from China?
Answer by ChewyJul 19, 2022
PetHonesty does not source anything from China. All of their ingredients are sourced from the USA with the exception of Kelp from Iceland and Turmeric from India.

so disappointed

I was really hoping my kitties would eat this. It’s really not a big scoop, but my 2 picky eaters wouldn’t touch their food and my not-so-picky eater ate it once, but by the next meal, she wasn’t having it.

Cats won't touch it

I mixed the product with their normal food. They will sample each meal and walk away. Going back to the other product that is offered.

Just keep trying

My cats didn't like this at first, but you have to slowly introduce it! They loved this stuff when they were kittens, but it's been a while since i've gotten it for them, so they were NOT having it. I mix it in with forti flora to entice them more and they eat it just fine now. Cats are picky, yall, but you gotta work around it and get creative instead of giving up after 1 try!!

Best thing since market allowed

I add this to my cats food and it has no taste and is so he’s for all cats. Especially my rag doll.

Will not eat

My cat would not touch her food after I mixed in a 1/2 a scoop into her wet food she usually eats. I tried a couple times. When will companies realize their so called flavorings do not fool cats? Can the make anything without flavor additives so you can get it in your pets that need the supplements and medications? I even get my vet medications done at expensive compounding pharmacies and the flavorings do not work well at all and are very inconsistent if you do finally get your cat used to one. Since many cats have herpes I really wish something could be created that will actually help them.

It's Perfect!

I needed a way to get Lysine into my cats. I came across this powder that has chicken and tuna flavor! It comes with a teeny scoop which makes it so easy to add to food. My cats don't mind it AT ALL. Like they don't even notice it's there.

Got sick

My two cats both got sick from this. They refuse to go near it. I wish I could get a refund.

Worse Lysine Ever!

My cats hate this stuff! They won't eat with this in their food. Wasted several cans of wet food. Smells horrible as well! Don't buy it!
