More Active & Playful

My cat has very sensitive taste buds! I was skeptical she would eat her foot with the Lysine in it. It's only been 5 days and she has eaten everything I've given her with the Lysine in it. It's a miracle! It's too soon to tell the health benefits other than to say she seems to be more active and playful than usual. This is a great sign already!

Well Its little early to notice much, but whenever I add it to my cats food, he just looks at it and walks away. He sooner or later eats it, but I get the feeling he is not impressed by it

Lysine for cats

It seems to be working. Was delivered on time and shipping was free. I did order from Amazon to get free shipping but since Coco offers free shipping I will order direct from now on.

My product came damaged and when I reached out to them, i got a fast reply and they also sent me another one! I am very happy with my purchase and it also really improved my cat’s constant watery eyes.

Works for our 16yo boy

Our vet recommended this product due to his life long-term battle with sinus issues and scar tissue. Great product, easy to use. Mix it in his salmon broth every morning and down the hatch it goes. Just like everything else with our finiky friends some will love it and eat it up, while others will fight it and be stubborn to the core. Best of luck to all.

Coco and Luna L- Lysine

I am not certain about how much he likes the taste for the L- Lysine. I am taking half dose of the powder (450 mg) and added a few droplets to form a paste. You can place it on the cats paw or I have also put on a small butter knife and put it in his mouth. My cat is picky, but hoping in a week, the sneezing is gone.

Using it for eye care.

Hopefully this will help with my cats eye problem. It was recommended by our veterinarian. Cant hurt him.

Helped My Indoor Cat

He'd been fighting off a nasty cold he'd had for a while(feral rescue), so I got this to help him regain some strength to continue that fight. He's doing much better now, healthy and happy as indoor cat.

Review later

I've only been using this a short time. I will review after we've taken it a while. So far my cats love it. I can mix with water and they will drink it in a cup. So far so good!!

Works good

My cat doesn't notice that I have mixed this into his food which is a good thing. So I am guessing it has no taste as advertised. Seems to be helping with his running eyes. Plan on repurchasing.

Easy to mix with wet food

I have an older kitty. Mixing one scoop with her wet food in the morning has been very easy. I started giving this to her after she had a bad kitty cold. The vet advised this for over all health. Shes not fond of chews, so this is purrrfect for her.

Love this

I try to keep lysin on hand for my FIV+ baby. I like how it dissolves easy in her food or water dish. Very easy to use w the spoon it comes with.
