My cat has FHV-1. What can a vet do to help her feel better?

Updated on September 23rd, 2025

Pet's info: Cat | Siamese | Female | spayed | 13 years and 1 month old

My cat Violet has Feline Herpes Virus 1. A few years ago, I had a cat that died from FHV-1. We would take him to the vet and they would give him a shot or something and he would feel better for about a month. He had a very severe case, but I think Violet's is minor. I don't want to go in for a diagnosis I already have. If I took her into the Vet, would they do anything other than tell me what's wrong? What would a vet do to help her? Thank you so much.

I have to say that I have never heard of a cat dying from FHV. It is normally a very mild disease, producing only a mild upper respiratory infection and occasionally conjunctivitis. Rarely immunocompromised cats (i.e.those that have other illnesses, such as feline leukemia or feline AIDS) can get pneumonia from FHV, but again, that's rare. Most cats that are chronically infected do well with supplementation with the amino acid lysine, which keeps the virus from rapidly reproducing, and keeps most cats symptom-free. In comes in a variety of formulations that cats will readily eat - try the brand Viralys, which makes powder, gel, and treats.
