Administering Lysine to Felines

Does Lysine Work?

For years this was the “go-to” for treatment. More recently, there has been some research indicating it doesn’t work as well as once suspected. As with any supplement, results can vary, so it’s hard to say. Many people still use lysine supplements for cats with feline herpes.

Many say the supplement works perfectly on cats who are not under a lot of stress. Research has shown that cats that at animal shelters sometimes do not respond as well to lysine supplements. The reason for it many not work as well is because of the extreme stress levels a cat can experience when at a shelter. Keep in mind, the cat is mixed in with other animals and is in an unfamiliar territory, so it is understandable how stress levels are elevated under these circumstances.
