Feral Catâs health
I read description and chose this for my 3 feral kittens. One had squinty eyes with one inflamed looking, you could hear the poor little one breath. All three were sneezing and under weight and skittish of me. Couldnât get close to anyone including mama whoâs mama Iâve known since a big kitten. They are ferals that I do my best to take care of. So I ordered this to try to help them hoping it would help. To get the little to eat, I put this in chicken dinner baby food by itself and with the páte I was feeding them. There is no special food for one with this group, good thing this is for cats health in general and so glad for mamaâs milk. I fed them 2xday with two scoops in each can two at a time to make sure they ate it all. I almost cried of happiness when two days later no more sneezing and her squinty non inflamed eye opened. Mamaâs milk helped. So I increased feeing to 4xday. And in a week she engaged in eating with the rest and her eye is so much better. So now all 4 kittens come closer to me as long as I donât reach for them and the two mamas. The third adult I think had a littler. The visiting Tom Cat chased my other ferals. Canât get rid of him. The kittens are so cute. Iâm trying to get the 3 them plump like the 4th one. I just ordered my second jar that should be hear today. I can not stress how much This Jar has helped my babies that I canât pet. This Jar has made me feel good that Iâm taking care of them and enjoying their play. The fourth one wouldnât play with the three. Thought their was something wrong with that one, til I heard the sneezing. Then figured that was the healthy one. I plan on getting another jar to keep them healthy. I definitely recommend This Jar to all cats!! Thank You for This Jar!! I have more cats and all of them gets this. I put it in their wet food 2x a day to make sure they all get some. This is my 3rd jar and not issues.

My favorite source of L-LYSINE!
L-Lysine is fantastic for cat immune systems and prevents cats with feline herpies from having breakouts. It helps clear up runny noses, eyes and congestion and can even help itching. It really is amazing. I give it to my cats regularly with their food and they love the taste of this one, so sometimes when they’re being picky about their food this helps. I’ve tried multiple different types of L-lysine but so far this is my favorite, I’m on my 3rd jar.

Probably unnecessary
I got this to help with my cats immune system and didn’t notice a difference in his health. I stopped giving this to him because it was clear he didn’t like the taste and I just didn’t see any changes in how he was acting (he had an upper respiratory infection for a year and even after giving him this in his food and having frequent visits to the vet it didn’t improve). After about a year of trying to cure his respiratory infection we finally got a medicine from our vet that actually worked, but this product didn’t help with his illness. Im sure this product has health benefits, but I just wouldn’t buy it again because I felt like it didn’t really do anything for my cat.

Excellent supplement for skin and fur
This supplement works I just days to help your catâs skin and fur. Their coat becomes very soft and shiny. This supplement contains probiotics, also, so I imagine there are positives not visible to us (as their coat is). I have three cats and each one looks healthier. I mix it into their wet food, and they happily eat the food. Very easy to use.

It works!
My dog brought home a feral cat a few years back, and she has been an indoor cat ever since. Recently she started coughing, and had a runny nose, watery eyes, and a bump near her nose. I tried getting her to the vet, but she does not like to be held. Needless to say I started doing some research and came acrossed this product. The first day she didn’t want anything to do with it. The second day I got her some wet food and mixed it in. The third day she was not coughing, no runny nose, and eyes. The bump starting going away. The fourth day, no signs of anything wrong. I still keep in the mix with her wet food. She is back to playing with my pup, and running through the house.

Verdict is still out..Kitten doesn’t like it
My 4 month old kitten had continual fever. He is a rescue. His body was healing from eye surgery and he’d already been to the vet to get antibiotic shots twice plus I had to administer antibiotics by mouth for 7 days straight. After all that, still a fever. So I got this and started sprinkling it on his food. I even tried mixing it in. Sometimes he’d only take a couple of bites and waste the rest. Sometimes he wouldn’t eat it at all. Some of the reviews said their cats gobble this right up. Not mine. So I don’t know if this did anything….or if the antibiotics in his system continued to work and do their job. He went back to the vet for follow up earlier this week and he no longer has the fever. I just wish I could get him to eat it as it seems to have a lot of natural health benefits. My kitten already has a beautiful coat, but some reviews said their cats eyes and coats got even more beautiful after being on this. I’ll keep trying to find ways to sneak this in but the verdict is still out as to whether it works since he barely eats it.

WARNING: This made cat VERY SICK
I donât leave reviews often, but wanted to warn other cat owners because this made my cat extremely SICK. Weâve tried 3 other Lysine supplements and did great with all of them. This one immediately gave my cat explosive diarrhea that he couldnât control (all over the house). His balance was off and had a hard time walking, and had a very uncomfortable, out-of-it look to his face. I didnât realize what caused it at first and I almost took him to the animal hospital. After this, he wouldnât eat for a couple days, so also didnât get lysine. Eventually he got better, and the moment I gave him the lysine, he was sick again. This happened 3 times before I figured out this Lysine was the cause. Since stopping it, he has gone back to normal with no return of symptoms. I donât know what is in this stuff, but Iâve never experienced anything like this with my cat (who is 16 years old). Please donât risk it – but if you do, watch your cat closely for a reaction.

My cats like the taste better than the more well-known brand and this one is a wee bit cheaper and is the same strength. My cats even stick their head in the jar and want to lick it!
