and the cats easily eat it with no problem

I run a Cat Cafe, and we use this for all of the cats to keep their immune system boosted. We had one with the sniffles, and the symptoms disappeared in just 3 days. I mix it right into the food every day, and the cats easily eat it with no problem. I am very happy with the results, and happier that even picky cats eat it with no problem. The jar is large, so totally worth the price. I think every cat parent should keep this product on hand.

Packaging and product change

Update- manufacturer wrote back and confirmed the packaging and product change -'Yes, we did recently downsize our container in an effort to save on how much plastic we are using for this supplement. And, yes, we did slightly tweak our formula to make it a finer powder in the effort to have it 'stick' to dry food easier. And we added 74 minerals to up the nutritional benefits per serving :)But rest assured, it is not a counterfeit product and it is still us! :)I do apologize for any confusion or inconvenience this may have caused you. 'Recently repurchased, the container and the product seem much different. The powder is much finer, almost like baby powder and while the label is the same the container is different. I've contacted the manufacturer to see if this is a change they made or if I received a fake product in my most recent purchase here.

Fantastic quality

I have seen a lot of different L-Lysines and this is the best quality powder I have seen. I would assume it is human grade quality so I am also going to take it myself!

Helped my chronically congested cat!

I have to review this stuff- we have had our 10ish year old cat for 6 years, and she has chronically struggled with nasal congestion and respiratory infections stemming from her feline ******. She has had antibiotics 3 times in the past year and they clear it all up, and then she is in bad shape again a couple of months later. We have used a different L-Lysine supplement that the vet sold to us, and I have used both powder and gel in that version, and I felt like I was doing what I could to help her, but it didn't really seem to make a huge difference. She flares up with stress and is very attached to my daughters, so when one went to camp this summer, BAM, sniffling, sneezing, coughing kitty. So, when we were going on a nearly two week family vacation, I wasn't sure how to keep her from becoming a congested mess, and she had been so bad a couple of months ago, we thought she might just stop breathing. She is happiest in her home environment, so my parents were going to come check on her every day while we were gone, but I didn't want them trying to give her the gel she usually takes, and by the time I thought this through, I couldn't get my hands on the powder version of that one fast enough... but I could Prime this one. So I thought, ok, better than nothing, and figured my mom could put some on her food every day. Well, to my great surprise we came home to her in better respiratory health than when we left, and she is still mildly congested and sneezes now and then, but overall, I would say this daily powder on her dry food has her feeling much better than she has in along time. If you have a cat with ****** and or chronic respiratory troubles, this is definitely worth a try!!

My Cat Gobbles Wet Food without Detection! Love it!

Yup true to it's claim. No odor or taste. My cat still gobbles up he's wet food without detention. Leo is super hard to fool. Since I just started giving him this stuff can't really comment on effectiveness. Poor Leo been through many health issues so I decided to supplement this in he's diet. I read very good things about Lysine & I take capsules myself, I no doubt it will work. It's pricey but if you have a finicky Cat this is the best purchase! I just give one scoop per day.UPDATE: Leo's been taking for 3 mos now. He hadn't had any reoccurring ear infections or gotten sick so I'm going to say this stuff helped? My senior cat has battled multiple health issues & this product has sustained him for sure. It doesn't hurt to try since there's no side effects or reactions.Update: 2019 hate the new formula... please change it back! Not 100% Lysine mixed with other stuff & 8oz measurement is incurrent. Much smaller in size. Terrible consistency, now more flowery Fine which is very difficult to scoop & pour. Doesn't seem to be as effective as the original product. Cats still gets goopy eyes. Therefore no longer using switching to another brand until they bring back the original formula.
