I am very satisfied! The cats really like eating it, and it strengthens their immune system. One of our cats had cat flu, which was already healing. But I feel that L-Lysine supports his recovery, and in general, he is very fit again :)

Doesn't help my cat that well, I expected moreBy Siska, Monday 5 October 2026Dr. Ann's L-Lysine - 50g
This is for a cat who had to survive outdoors for 2 years and has feline herpes. He has since been neutered and was given antibiotics, but the antibiotics didn’t help, which is why I’m trying this now. He’s been on it for 15 days straight, and unfortunately, there hasn’t been much improvement yet. I will keep giving it to him and hope for better results soon. He is eating and drinking well.
