Review: Great absolutely recommend - My cat deals with a low level chronic respiratory infection. This ailment seems to affect white or orange cats more than others and he is a white siamese mix. His only symptom is constant black boogers in his nose. My vet suggested lysine treats so I ordered these. He has been eating two treats twice a day for almost 2 weeks now and his black boogers have decreased so much. I used to have to clean his nose every day but now it's every couple days and hopefully after continuing these that will go down even more. He loves the taste but I do break them in half as they are a little hard for him to chew otherwise.
Review: Ray Charles begs for these treats. - One of our cats, Ray Charles, has feline herpes. He has always struggled with wheezing and sniffles. We have tried everything from Lysine gel, powder, and other treats. Ray Charles loved the GNC pets Lysine treats but they stopped making them. After several other tries with different brands and him turning his nose to those other brands, I found these. I read the reviews and I gave them a shot. RAY CHARLES BEGS FOR THESE. He loves them. They are chicken flavored and soft. I agree with the other reviews that say they are a little too large. Ray Charles is a tiny cat so I usually break each treat up into three pieces. These don’t eliminate his symptoms but they do greatly decrease them. HIGHLY RECOMMENDED.

### ⭐⭐⭐⭐ My cats love these
*by S***E on November 20, 2025*

I have had my cats on these for years now, I’ve lost count of the amount of packages that I’ve purchased. This is the only brand that I will buy because it’s the only brand that my cats will eat. I have to cut them in thirds for my cats or they are too tough to chew and they won’t touch them. I cut the tail off and then the main part in half, perfect size for them. Once I do that they get excited for their treats. I got one of my cats when she was 10 weeks old and noticed that she was sick right away. The vet explained that she had a cold caused by the feline herpes virus. She’s twelve now and if she doesn’t get the chews then she’ll have a cold within days. A couple of years later, I adopted a two and a half year old male cat that also has feline herpes. Without these chews his eyes get junky and he gets the cold symptoms just as quickly. They both know when it’s treat time and will sit in front of the counter and meow until I look at the clock. I recommend these to anyone that has a cat with feline herpes. If your cats won’t eat them, try cutting them in half, it might help; did with mine.
