Excellent product!
The best I can say is this product really works and quickly plus my cats like it. I use it when they have sneezing and/or watery eyes. It mixes into their wet food easily. As they have gotten older, I give them this supplement most days. It is great for their immunity. I ran out recently and one of my cats was sneezing day and night. Within the second day of this supplement, he is fine again. It is a wonderful product.

Helps with respiratory problems
Have purchased this product for the last couple years. I have a black fur baby who lives outdoors. While most of his time is spent on a fully enclosed deck he is susceptible to upper respiratory problems. Since I gave been giving him this everyday to help build his respiratory system he hasn't had anymore problems. I mix it in his nighly squeezable treat. Been 2 seasons now without problems. Will continue to give it to him even during the warmer months. We live in south eastern Washington where it gets fairly cold in winter and hot in summers. This product works! I give it to another outdoor cat who doesn't have issues . Highly recommend for all your fur babies.

Good product keeps my cats healthy
Fine powder, cats like the taste, needs to be mixed in the food well. Cats fur and nails are healthy, shiny. Helps keep them healthy all year long. For 3 cats it's lasts about 2 months

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!

It works!
My cats and kittens like this! I mix it with their food. I have a kitten who has a mild cold and it seems to not get worse and help with the other synptoms compare to before when I had a kitten who had a cold and wasnt using this. I highly recommend this!

Great product
It dissolves very well in the wet cat food, the cats absolutely love it, and it makes their coats very shiny

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 Job👍🏼, 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.
