My cats love this L-lysine mixed with their wet food or in the puree lickable Delectables by Hartz. There is this tiny scoop you use twice a day. It should last quite a long time but I have already ordered a back-up. The soft chews by Tomlyn they also love and I break in pieces . I have tried 3 different chews and these are the only chews they will eat as well. My cat had a feline herpes outbreak and a terrible pink runny eye that she could hardly open and sneezing. Unless they get a secondary bacterial infection antibiotics are not effective for this viral problem. Within about 3 days she has stopped sneezing, her eye is better and she is not lethargic. I try my best with rescues cats and spay and neuter but vet costs are mostly impossible.
It mixes easily into my cats' food, and I've noticed less sneezing and better overall health.
Excellent vitamin for cats I recommend it.
this helped my sick feral stray when they had an URI and since then Ive noticed a huge change in their weight and overall health
Great for treating my pets with vision irritations
Easy to dispense and they seem to like it
Unfortunately it did not work on my cats allergies. I do know that lysine does help with allergies, just not my cats particular allergies.
I have 3 cats and no matter what I mix it with, they won't eat it. IDK if it's taste or smelll but cats are so much different from dogs~~~they don't care if you threaten to take away their Birthday!!!
The container arrived half full. Don't know if we got all we paid for. Smells like old fish. Cat eats it mixed in food. But it does not stop her from sneezing, not at all.
My cats wouldn't even taste the food I put this in. Waste of money.
