A. If your cat has had chronic upper respiratory issues she may benefit from a supplement such as lysine. Lysine can help boost the immune system and is often used as a supplement in cats that have chronic respiratory viruses acquired in kittenhood (many stray cats will have this virus) to prevent the virus from causing serious health issues. If that does not help and you are concerned about your cat's symptoms, seeking additional testing or a second opinion with another vet may be helpful.
