Best l-lysine product so far!
I’ve tried several of the treats containing l-lysine and one worked for about a week and he won’t even touch any of those treats anymore and is weary when I give him normal treats now.This powder mixes in with wet food very well. I open the food package slowly so I can get ONLY the juices and oils into a condiment bowl. That’s where I mix it up until no chunks of the powder are seen. Then I scoop the wet food out and put it on one side so the mixture stays a bit separated. Works like a charm! I give him 500mg twice a day, once for dinner then a dry food lunch and another 500mg before bed.

Helps kittens immune system
This product is so easy to use, I love the fact that it is a powder that can be mixed with there wet food. My Maine coon kitten was very congested but since I have been using this product he is not sneezing as much, he is more active. I would recommend this product to anyone who is buying a kitten from a breeder.

Excellent supplement for cats!
I bought a little sphynx kitten and she had some runny eyes and sneezing. A vet friend told me about this product and it is wonderful! Cleared her right up. I do give it to my cats weekly just to keep their immune system strong. They love the taste!

Less snot flinging already!
This is Ella. If her boogers were darts, she would be a pro. She often managed to hit my glass full of wine! But I digress, this is a review of the product, snot about her accuracy. She has had chronic congestion for years. Vets have made suggestions that I’ve tried (benedryl, baby cold medicine) to no avail. Why? This cat can smell meds in any food and giving her a pill is like getting a haircut from Edward Scissorhands while he is drunk. I had given up and resorted to using Clorox wipes to get her flings off windows, walls, fabric, etc. It was the only thing that would get it off…oops, veering off target again. I was reluctant to try this stuff but seeing that it was a powder and salmon flavored (not bubblegum for crying out loud!) I decided to give it a shot. I only gave her a half dose at first and it made a difference the first day! One dose is a lot of powder that tends to stay at the bottom of the bowl. Wet food is best but this weirdo doesn’t care for wet food. I just have to figure out the right mixture of wet and dry. Anyway, other than her poo being like gel (hopefully temporary), it is working very well. She is sleeping better and I am too since she lays right beside me (her nose doesn’t whistle anymore and I don’t wake up with boogers in my hair). Here’s to better days and nights. Cheers!

Great supplement
I heard my cat sneezing and jumped on Amazon to find a supplement for him. I found this one. Great price and I received it the same day. I put a scoop of this in his food and he ate it right up. So far so good. I already know how great this supplement is for cat’s immune system, so I’m happy I found this at a good price and my cat will eat it in his wet food with no issues.

New Product Line is Horrible and a waste of my Money!
I have been using this company’s pet products for about 10 years now. I have 8 cats and each of my kitties would eat their food with Coco and Lunas great quality Vitamins(especially their L-Lysine). UNFORTUNATELY, THAT IS NOT THE CASE ANY LONGER!!! COCO and LUNAS NEW PRODUCT LINE WAS RECENTLY RELEASED(which included New product cosmetics and RECIPE CHANGE for all their products). NOT ONE OF MY EIGHT CATS WANT TO EAT THEIR DINNER WITH THE COCO and LUNAS NEW L-LYSINE. My oldest baby is now scratching & itching after he eats his dinner with COCO & LUNAS new L-Lysine. They were using Grade A ingredients for all their products and it seemed liked they actually cared for our babies wellbeing. This company, just like most, has sold out. They are obviously not using Grade A ingredients any longer, just so they can make an extra buck at the cost of our furbabies health/wellbeing! This is unfortunate because I was buying hundreds of dollars of their Vitamins per month. Now I have to start from the beginning, research Coco & Lunas competitors and find a company who hasn’t sold their Soul for money. U just made a big mistake, I was a loyal customer with your company for YEARS and spent a ton of money over the past 10 years. Now imagine, how many other customers had the same loyalty, spending habits that you will lose just this year alone. Was it ALL WORTH IT??? CUTTING DOWN/REPLACING YOUR PRODUCTS QUALITY INGREDIENTS, U THINK U ARE SAVING MONEY??? I CAN GUARANTEE THAT IN THE LONG ROAD, U WILL LOSE MUCH MORE THAN YOUR CUSTOMERS!!! HORRIBLE CHOICE MADE BY COCO & LUNAS CEO’s, VP’s & let’s not forget their board members! Good Job everyone , Good Jobðð¼, HELLUVA of a Job. “The clueless shall inherit the Earth”

My cat didn’t like it
This is to help a cat’s immune system. Mine has FIV, and needs all the help he can get. I think this is a good product, but my cat hated it. He refused to eat any food that it was sprinkled on or mixed in, even salmon pate.It is a very fine powder that will clump when sprinkled on wet food. It reminds me of damp cornstarch. Perhaps that is what he disliked.I can’t find anything bad about this, it just didn’t work for us.

Repeat purchase- Works well!
This is my third purchase of this. It mixes nicely into a Churu treat squeezed into a small dish, and my cat seems to like the flavor in combination with the Churu. I use this when my cat shows signs of having a herpesvirus flare. She was a feral, rescued, and like most shelter cats, she has herpesvirus, and it glares occasionally. This stuff works well and is easy to administer. I wish Iâd known about this when I had my previous cat; his life could have been so much more comfortable.

Simplesmente mudou a vida da minha JuliEla sempre tinha imunidade baixa, lágrimas ácidas, gripe principalmente por conta do frio que faz em Curitba. E descobri esse suplemento, dou todo dia pra ela com a refeição, e ela não se importa. Melhorou dos olhinhos, gripe nunca mais e tá bem mais ativa. Não deixo faltar mais, agradeço muito por esse produto! E eles são muito atenciosos!! E chega rápido!
