I have used multiple tubes for my cat upon my vets recommendation since he was a kitten and now he is five so I can safely say this helps to keep his coat smooth and shiny and also helps with his overall health, energy levels and gut health I feel. He takes this easily there are no offensive smells attached to it. Check with your VET before you start. Read more

Works soooooo well! Especially helpful for feral cats you can't just pick up and take to the vets. 100% More energy and less sneezing, runny eyes or nose. Why maple, but it works. Read more

My vet recommend this product for my Fiv positive cat, to boost his immune system. He lacks it up easily from the top of his wet food. Read more

Does this stuff actually work? It seems to. If you have a cat that's sick or seems to have a mild respiratory infection, especially a cold that keeps coming back, this stuff does seem to help them. I've had vets recommend it, and if you have cooperative cats it's not hard to get them to swallow this stuff. (If you train your kitten to let you give it medicine, it'll be cooperative as an adult.) This is maple-flavored, and I don't know why. I've known a lot of cats, and I've never known one that likes maple flavor. I mean, why would they? A lot of hairball gel is maple-flavored nowadays, too. Mysterious, but so it goes. If you put a lump of this on your fingertip and smear it into the cat's mouth, most cats will lick and swallow it. Some may spit it out, in which case you'll have to gently hold the cat's mouth closed for a few moments, but they don't usually *hate* this stuff. All in all, we feel this is worth the money. I can't prove it works, but I'm pretty sure it helps, and it's not hard to use. I've never had a cat show any ill effects from it. I just wish it wasn't maple-flavored. Read more

Took my cats a little time to get used to. It's maple flavor. It costs more than others. I keep this one and another brand on hand bc my female seems to sneeze a lot. Indoor cat so vet thinks maybe something she picked up from outdoors. She was a shelter cat. Has great health benefits. Good quality. It's cheaper on here than at the vets. Smells like maple syrup.

Lysine is an immune booster & very helpful for immunocompromised cats & dogs. My vet prescribed lysine for my dog that I measured out & sprinkled on his food. Then my 21 yr old kitty caught a cold while I was sick too & vet prescribed lysine in this gel Viralys form daily for him in his old age to help keep him from getting sick. He lived to be 23! The gel form is much easier to give to cats & they either like the flavor or can’t tell when it’s on their food (I’m not sure which); & can be put directly on the tongue if using a syringe. I just put a 1cc needle-less syringe to the tip of the Viralys tube & draw while squeezing a tiny bit on the tube & no waste/no mess. I just put 0.5cc on top of my kitty’s canned food once a day & the tube lasts quite a long time for 1 cat, so not bad! Sadly, he was my little antique by time he reached his 23rd b-day & departed. I’m now using Viralys to help keep a FeLV very immunosuppressed cat from getting sick (along w/ no exposure to other cats or any sick people & keeping her indoors only) so she can live a happy life as long as possible w/o succumbing to every virus & bug that comes near. It’s a challenge but one of love. So I immediately started her on Viralys in hopes that it might help even in this severe case. For most pets, this is hands down a very good choice!! The verdict is still out in the case of the cat I’m trying to help that has essentially no immunity at all, but it sure won’t hurt her & just might help a little too. I do know it’s a great product from my own past experience & also because it was vet reccommended for my sweet ancient little guy as well as previous knowledge & use of lysine for people & dogs.

My vet recommended this for an outdoor cat that I had brought indoors. I was skeptical but it actually worked to clear up her congestion and watery eyes and she gained weight. I can't say that she really liked it despite the maple flavoring, but the main thing is it worked. Read more
