Good product for sickly cats
Cats were sneezing , runny noses, eye issues. I mixed a little into their food, twice daily at first, then once daily, and after a week rhe sneezing is subsiding and they are almost back to normal. Highly recommend

lots of lysine in smaller quantity of powder, 9 cats love it
I've tried five brands of powdered lysine, two brands of lysine treats, as well as the old sticky Viralys and this is mine and the cats favorite powder based on taste. I take in stray cats and calicivirus and respiratory issues are non-stop so I've been supplementing lysine for years. FLAVOR-All 9 of my cats love the flavor this brand. I mix it with canned food so I can be assured each cat gets the correct dosage. I do not sprinkle it on dry food as then I can't tell who got what. DOSAGE-this one is my favorite as it takes a much smaller scoop to deliver 900mg. The other brands of powder I've tried vary in how much powder/scoops you need to use and how much lysine you'll get. This one has the smallest amount of powder, a therapeutic level of lysine, and the best flavor. Other brands can have much less lysine and/or require larger amount of powder. I've tried two brands of chews, one has very little lysine in it and it was universally hated by the cats. The other is loved by all the cats but has a lower (500mg) amount of lysine. Between that chew and this powder they get the appropriate levels. So this is my favorite powder and my cats willingly eat it. Everyone's happy.

Found that my cat eats it with his food
Why did you pick this product vs others?: So far my cat is eating his food with this mixed in it. I have had trouble with a few others that. Y cat would not eat. So far this has been my best solution for him to get his lysine.

Excellent product. I believe this saved my cat
Walter has a long history. He showed up Jan 2019 with my feral colony of 7 cats. He had two litters with the only female before I was able to trap her and had her fixed. I thought he was feral. So, Sept 2019 I trapped him and had him fixed. He was big 16 lbs. He disappeared Oct 2019 and returned Thanksgiving 2021. He would come late at night to eat and I did not recognize him. scrawny, little fur and sickly. He came 5am one morning and I followed him. Found where he was sleeping in a neighbor's garage, 3 streets from me( a long walk). Jan 6th 2022, he came to eat around noon, sat in my garage and never left. He had a terrible nose infection, lots of mucus and bleeding, and his meowing was horse and horrible. when he would sneeze, his nose bled a lot. I took him to three different Vets. One said he had a tumor in his nose. Tried several Rxs. nothing worked. To remove the tumor and treat if it was cancer was out of my pocket range. So to the L-Lysine. I read a lot about it. I gave him every am and pm. from Aug 2022. Four weeks ago the bleeding stopped, he is breathing better, meowing normal, but still has a snatty nose and would blow out some mucus now and then. He was 9lbs and diabetic when he returned. Now he is 16lbs with lots of fur. I believe that supplements do help a lot, (from personal experience) and would continue to give him this L-lysine.

Cat Loves the taste and he never gets sick anymore
My cat loves the Strawfield L-Lysine. When I brought my kitten home he came down with sneezing and runny eyes. He was so lethargic. When I gave him the L-Lysine he ate it eagerly and I could see he felt better instantly. I stopped giving it to him for a month and when I heard a sneeze I started it back up. I have been giving it to him daily and he has never gotten sick for the last 3 years.

Nah
My cats don’t really like the taste or smell of it. It does have an icky smell that I don’t even like. It’s also clumpy.

Great product, more ounces than most other brands
This product may seem expensive at first glance, when you're comparing items to buy, but then with further scrutiny, you realize that it has Many more ounces per jar than most others, and if you're using a lot of it often enough, than it's worth it to spend a little more for more ounces of product. I do cat rescue, & have feral cat colonies I care for, so I do go through quite a bit of L-Lysine. The product is a finely ground powder that is naturally liver flavored for palatability & compliance. Cats can be pretty picky w/ certain flavors, but I haven't had any issue with non-compliance with this one. I highly recommend it!
