Review on 🐱 Felisyl Immune System Support for Cats - Enhance Feline Health with L-Lysine - Boost Antibody Production - Support Respiratory Health, Vision, and Tissue - 60 Soft Chews by Andrew Pierceson

Revainrating 3 out of 5

Doesn't seem to work

I know L-Lysein works for herpes because it works for my herpes. However, it didn't seem to have any effect on my poor cat with feline herpes. He has the same sneezing and runny nose, after 2 weeks 2 (i.e. 500 mg) a day.

Pros
  • Weight
Cons
  • Incredible piggy bank
