Tiene un sabor que gusta a los gatos y según el veterinario tiene una muy buena concentración de lysine

Just had to chuckle as the review asked me to rate flavor, I assume it is OK because the cat doesn't refuse to eat his food with this mixed in.So far it is controlling my cat's weepy eye problem as well as the expensive brand from the vet.

It smells fishy but the cat likes it and it's not so terrible that we humans can't tolerate it. The cat also seems to enjoy the taste. I can really tell that it works for her though because we've run out and almost immediately she starts to sound "rattly" when she breathes. Very happy with the purchase.

Great value

We all know l-lysine taste horrible, but this is flavored. They won't eat it by itself yet when I mix it with moist cat food, they will eat it. The unflavored type of lysine mixed with moist food is harder to get them to eat .This is a little more expensive but it's worth it

My cats love this mainly because of the yeast smell. They will eat food with this sprinkled on it. Disappointed that it was open and don't know if any had been taken out because it was certainly not full and hopefully it's safe

Highly Recommend! Worth every penny! We were recommended to purchase the Felisyl due to our two cats getting continuous colds their first year. We have been using this product for over three years now and it's the only L-Lysine product I trust to give my fur babies. The cats go crazy over the taste- they get so excited when I sprinkle some on their wet food. It lasts a good while. Only down side is that it get's stuck together sometimes, but I can break it apart easily.

Purchased for my kitten to encourage him to eat his food. It has helped him he is eating his food.

My Dad has a colony of ferals that have become outdoor pets. Recently some have began sneezing and coughing, trapping them and taking them to the vet wasn't an option so I researched what we could give them without a prescription and found this. Not only will they eat it out of his hand almost by itself; but their sneezing and other symptoms are almost gone. Definitely recommend this stuff, especially if you have a multiple cat household.

this little one eyed FIV+ baby was sneezing his head off the first week he was home, but after just a week using this he's barely sneezed at all & no green snot.hoping it'll help keep the vision he has left! & i have high hopes!

The cats love the flavor. So easy to get them to take their probiotic because it takes so good.

I use this for my cats who have colds or sniffles on occasions. Also for chronic issues that now only flare occasionally. It is a little expensive for the amount you get compared to the non-flavored L-lysine. Also it is slightly granular, which I don't perfer, but so are the other L-lysine products I have purchased. It seems they taste the difference in texture and some animals seemed initially turned off by it. After a while they seem to get used to it. If it were a finely ground powder it would probably be more palatable initially with less rejection. BTW it does seem to work pretty well. Have been using L-lysine based supplements for those conditions for years.

Bought for my sneezing kittens. Wanted to help build their immune systems. They were born on a porch. Most likely have feline herpes. They don't mind the taste and I love the measuring tool it comes with.

My kitten was very sick and my vet recommended me to buy some immune System Support product for my cat. This thing helped my cat A LOT. She is now the healthiest cat I have ever had! She runs and play all day. Much recommended!

I put 1 cup in wet food for my fur children and they ate the food without any issues. Thank you this is a very good product and yes I recommend it :)

My catsLove the taste and run for the bowl. This makes me happy to know my cats got their vitamins

Works great. My cats loves the taste and would eat it out of the container.

My cats really like the taste. I'm hoping it helps their drippy eyes because I cant keep them on antibiotics forever.

Poor kitty had a number of health issues, so vet prescribed Felisyl. He was much better after a month and continued treatment until it was all gone. Much happier and healthier now!

My cat will eat this right out of the container without waiting for me to sprinkle it on his food, so I can't remove the lid until I'm ready to use it.

I have senior kitties in my house and this winter will be very harsh in New England where I live. It's much smarter and less expensive to protect my kitties early than it is to take them to the vet later. Felisyl L-lysine powder sprinkled into their canned cat food is the best way to help boost their immune system to fight off colds, runny eyes, sneezing etc. They just feel better when they're on Felisyl.

My cat does't want it.

My cats don't even notice it when sprinkled and mixed with their food

THIS PRODUCT WORKED FOR ONE CAT BUT NOT AS WELL FOR THE OTHER. THEY ARE MOTHER AND SON. I CAN ONLY ASSUME, SHE EATS MORE OF THE FOOD WITH THE PRODUCT IN IT OR HER IMMUNE SYSTEM IS SOMEWHAT STRONGER THAN HIS. I PUT TWO SCOOPS OF IT DAILY IN CANNED FOOD TO WHICH I ADD A CAN OF WATER. I LEAVE IT OUT FOR ABOUT 30 MINUTES AND DON'T MONITOR HOW MUCH EACH CAT EATS. IT HAS HELPED HIS HEAL, SOMEWHAT BUT NOT AS WELL AS HERS. THEY MUST LOVE THE FLAVOR SINCE THE PLATE IS CLEAN EVERYDAY.

I mix product with their food and they eat with no problem. The tiny scoop makes it easy to measure amount. Hope it does what it claims. Haven't notice any major difference as of yet.

Works great

Cats both ate it no problem.

Spiffy product

I ended up putting these in a large empty spice container that I washed out super good and I shake them on the food

Mixed this in with wet food. They didn't even notice. Will buy again.

I've been using this product for over 2 years for my cat who has FIV. It has minimized frequent respiratory issues. I sprinkle and mix with his wet food, as directed.

Works well and cats like it. My new kitten had a runny nose and after adding to food for a week it cleared right up and she has been fine ever since.

perfect organtic antibiotics. they are great. cats love to eat it. fine powder with a scooper included. lots in a small jar. it will go a long way. it worked withint two doses.

Just sprinkle it on and all their runny noses and yucky eyes get better

I got this for my cat with allergies.

Much more economical to purchase the l-lysine support he needs here! It is not the same brand, but he happily consumes it with every meal!

Great for keeping the kitties healthy! I give in every meal. Recommend by my vet!

Really helps my cat with URI

Use this for a stray that adopted me. Her health has been turning around ever since

I have multiple kitty household and this is the most important supplement that I can give them. They like the taste and or smell. I just sprinkle on their food every day. One container last a good month, not too costly to be used every day.

It gave my one cat the runs.

excellent product, my cat loves it and she stopped sneezing , and this power has taste like fish so its wonderful product,

Really works, builds immune systems

Only been using it for a couple days, but it seems to be good so far! My cat who needs it wouldn't touch the lysine chews, but she doesn't seem to notice this at all! Happy that I can boost her immune system without any trouble.

After over 2 years of trying everything from prescription meds to over the counter allergy pills to organic help this stuff seems like a miracle! She has had feline herpes since she was a kitten & used to just have bouts with it maybe twice a year. The past 2 years she has been sneezing, snuffy & feeling horrible almost constantly. My finicky cat has no problem eating it when mixed with wet food & her health has improved greatly since we've started using it. Funny I got the request to rate this when I was about to order another container.

it gave my cat HORRRRRRRIBLE diarrhea!!! The company was really good about getting me a refund though. So 1 star for the product but 5 stars for the of the company itself.

Works great! My youngest kitten was diagnosed with herpes. He had chronic sneezing, watery eyes & runny nose. The vet prescribed lysine & charged $26 for it! I ordered this and it works just as well. One scoop twice a day in food. No sneezing, runny eyes/nose. Just s healthy & happy cat.

As advised by our vet, we use it daily mixed with wet food for a shelter rescued cat with chronic herpes-like upper respiratory virus. It seems to reduce his sneezing & eye discharge and prevent more severe symptoms. We have tried the much cheaper human grade lysine powder, but kitty prefers the taste of this brand that adds flavoring. I think this works as good or better than other brands. If you can't afford this though, I would recommend the large container of lysine for humans ( made in USA) but using 2 scoops (the ones included with cat lysine) instead of just one per meal or day depending on symptom severity. It gets expensive using every day for years or for more than one cat.

This seems to work at boosting my kitties immune systems. I recently took it with me when we evacuated from hurricane Irma. My cats tend to get sick from stress but we didn't have any of my 5 cats get sick while gone for 5 days even though they were super stressed out. They like the taste too. My cats are picky and usually if they see I added something to their can food they won't eat it, but they seem to like this and will eat their food right up with this in it. Good product.

This has helped by sick cat for the last 8-10 years. He has herpes and gets symptoms (red inflamed gums and his eyes tear terribly) that only this has helped His litter mate was taking supplements prescribed by a vet for the same problem and passed away 5 years ago. Great product! I will keep using it!! I found that if I missed a few days his gums would start getting red and he would get black tear stains around his eyes. Had to make it part of his routine everyday
