    My cat suffers from rhinitis and has a permanently runny nose. Adding this to his food helps to control that and he has become noticeably less affected by it since we started using it. The lysine is in a pink translucent gel which is easily camouflaged when mixed in with wet food and I guess there’s no noticeable taste since he doesn’t notice its there. Highly recommended if you have a sniffly cat

  2. H Nix

    Cat is 17 and was not in brilliant condition, Vet thought she might have Neutropenia a white blood cell deficiency which left her vulnerable to infections, so recommended this. My goodness what a difference, glowing coat, bright eyes, runs around(for a short time, but still runs around on furniture, leaps on chairs and seems to be her “old” self)!! I do believe the Lysine Aid plays a big part.
