Description
Felisyl® is a soft chew supplement that contains the amino acid L-Lysine for use in cats and kittens for conditions responsive to L-Lysine.

Felisyl L-Lysine HCL Immune System Support Soft Chews for Cats also helps maintain healthy tissue, supports respiratory health, and may even help with your cat's vision. The L-Lysine is in a chicken liver flavored soft chew making it easy to give to your cat.

Lysine is good, but cat won't eat it
I think the Lysine has been helpful in reducing my cat's symptoms. However, this cat will eat ANYTHING...except this! I have to break up the pieces into little bits and stuff them ino her canned meat. She still resists, eating around the bits most of the time. I will try a different brand of Lysine and hope she will eat it. I bought a three-pack and donated two of them to a local animal shelter

Felisyl
The cats are not eating this treat and I have 11 cats, none of them liked it. I ended up giving them L-Lysine smashed and mixed with their food.

he won't eat them...
even if I break them up into tiny pieces. They're not soft enough for my old guy. I found another brand that are softer and he'll eat those.

It all depends
They are a little tough so some cats won't like them. I have to kind of squish them a bit so the break up for my cat and even then, she is not thrilled with them.

Bad Purchase
I have two cats, one I call the goat because he eats anything including things like duct tape, paper and who knows what else. Well neither cat will touch this stuff. I gave it to them and they didn't even think about it, just sniffed it and walked away. My neighbor has three cats and we tried it on them and the same result. Waste of money!!

Not the same
I usually buy Vetri-Lycine for my cats; 250mg l-lycine chewy treats that I give to the ones who need it (four or five) and they love it. We make it a fetching game.
I thought it wouldn't make a difference buying this brand instead - Felisyl - and they completely rejected it. They would chew it and spit it out. I was left with gooey lumps all over the kitchen floor. I unfortunately had ordered multiple bags but rather than go through the hassle of trying to return and get a refund, I just threw them out.

Great and the cat loves them!
Used as therapy treatment for my Tuxedo who was exposed to Feline Herpes as a kitten.
Works wonderfully--only wish each chew was 500 mg instead of 250mg.

Helps Eye Deposits Reduce dramatically
In a few weeks, with twice day dosing, she ate it with her dry food but I HAD TO DICE IT UP BECAUSE IT IS TOO HARD FOR HER TO CHEW BUT she ate it if cut up and mixed with her dry food. She is very finicky and ate it. Her eye issue and breathing improved the first week by 50% and the second week by 90%. Once a day she may have some issue and I give her one a day now and one day she had no eye deposit in her tear duct and it has only been two weeks! The product needs more moisture though because even sealing the bag it does dry out to become very hard when the bag still has 1/3 of the contents left at 2x a day.

Most Economical
My vet had quoted me an outrageous price for Lysine when my cats came down with a herpes virus. This product keeps them symptom free at a fraction of the cost!

Was the formulation changed?
Last winter I purchased a three pack. My cats loved them. They were "fish" flavored, dark colored and moist.
I recently received a six pack shipment. These are chicken flavored, beige tan and harder. All three cats turn up their noses and walk away.
What happened to the formulation? I don't remember there being a choice of flavors.

My "go to" Lysine chews
I have rescue cats and some have "eye" issues and benefit from Lysine. Well, there are many forms of Lysine out now, thank goodness but all of the ones my cats are supposed to like...they don't! They are so difficult!! Anyway, These chews are the most moist you can get and are easy to chew. I just widh they had more Lysine per chew, and for that I would add the 5th star! Can't have it all though huh? Thank you!

Great L-Lysine Treats
The cats love them. Not real hard to get them to eat them at all.

Good for the kitties :o)
Several years ago we adopted two kittens who had upper respitory issues. Our vet suggested trying L-Lysine. It helped get them healthy (I believe) and I really think by keeping them on the L-Lysine it helps keep them healthy.

good flavor
We have 4 cats on L-Lysine. The treats make it much easier to administer than pills or powder. All the cats like the the flavor of Felisyl .

Felisyl
I purchased these as back up in case I run out of the Enisyl-F paste. The kitties love them so I think it's a good alternative to the paste. Only problem was some of them were broken up so it affects the proper dosage.

One of the Best purchases ever.
My Cat Lilly is doing good on this product
her sniffles and sneezing are lessoning.
It is much easier to give her the treat.
Though I must cut it in three pieces and
put it with some of her other treats.
Its much simpler to get her to eat her
immune support soft chew. That is why
I reordered 6 more packages. She is currently
doing well on 3 treats a day. She is also
much more alert and active. with her upper
resputory illmess.I would recommend this
product to other cat lovers. Try it.
