Feline Herpes Virus

Hello all, I am new here.

I have a kitten, about 5.5 6 months old that has feline herpes virus. I was just wondering if anyone else had a kitty like this and how do you control it??

I use L Lysine 500 mg a day in his favorite cereal and veggies (He is very fond of baby food and will NOT touch wet cat food)

Any suggestions are appreciated.
Thanks everyone in advance =)

Hi there!
Many of us have kitties with herpes here... L-Lysine is probably the best thing to keep a flare up at bay... I am just not sure if 500mg is too much for a kitten... But if that is what the vet said.... My thoughts would be more in line with 250mg a day. My adult 18lb cat takes that 500mg a day.

What do you mean cereal and veggies? I hope not literally?
You should not be feeding that to a cat. I hope by "cereal", you mean his dry food.

Also, he probably should be on a grain-free diet (no corn, no wheat, no soy), as grains are bad for herpes.

If you give him baby food, make sure it doesn't have garlic or onions, as they are toxic to cats.

Yes that is what the vet prescribed 500 mg a day.

His cat cereal and yes baby food, baby food doesn't have garlic or onions in it!! Its the veggie AND water, no salt either.
Why does this site have so many advertisements at the top?

Thanks by the way! I totally forgot to thank you.


I have ten cats, I am well informed on what is toxic to their little systems. I have had to throw away many lillies in my lifetime! Haha!

One of my cats has herpes. I have kind of figured out that it needs to run its own course. I occasionally give him viralys (bought at vet) (l-lysine) as well as regular l-lysine supplements in his wet food. Occasionally he will have very bad flare-ups and I will have to call the vet and they prescribe him steroids and antibiotics. It's gotten so bad once that he had to get a nasal flush (also done for diagnostic reasons as well). I just try to minimize his stress as much as possible, because stress causes severe flare-ups for him. And I make sure to always have water available for them.

I was just kind of lurking and reading.. but I saw this wasnt answered.

This is a "free" site.. or at least its free for you and I to use. nothing is really "free" in life tho.. the domain name has to be paid for somewhere, those can cost several hundred or more a year (a friend of mine runs a more simple forum and I think she pays about $300 a year for the domain name!).. so, you get advertisers who pay to put their ads up at the top.


I believe you can be a paid/premium member on this site, and you wont see the ads. I dont know what perks come with the paid membership tho, but if you are interested, Im sure an admin would be glad to tell you about it.

I have a cat with herpes also and use lysine.
I also give her chicken ,beef and turkey baby food.

Thanks everybody! I guess for now I am just doing the best I can with him.

Thanks again!

about the ads - for my web browser i use firefox with adblock plus and i didn't even know they were there

I keep my home warm when its cold as well and use a humidifier. I try and make sure she doesn't get near the drafts. But some fresh air is good also (for everyone in the house) so I air out for 5 mins every weekend. I notice a difference with her if she gets too cold or the house gets too dry.

It isn't always a worst case scenario, some cats can live very well with this virus. I don't have to use the lysine everyday anymore for Fiona. I just do it if I notice she is having more disharge from her nose and eye and want to help support her immune system through that. Usually happens only once a year or twice a year with change of seasons.

My kitty with herpes virus is on a maintenance dose of 500 mg lysine every other day, but if he shows signs of a flare up I put him on the therapeutic dose of 500 mg daily.

He has been taking l-lysine for 8 years, after all out infections that almost cost him his eyes.

Baby food is okay once in a while for a cat, or if the kitty is ill and needs to get food, any food, into him, but it is not a balanced diet for cats or especially kittens.

If you are giving your kitten baby food every day, that is less of his balanced food he is eating. I strongly urge you to stop the baby food, except as a treat once or twice a week.

(and yes, some baby food does contain onions and garlic, reading labels is important )

Welcome to TCS!

I do read the labels and I don't get the 3rd stage, first ONLY. Which is pretty much water and makes me want to puke by the smell lol!

My vetrinarian has him on the l lysine and he said to bring him in if he gets a really bad flare up for a steroid shot. He is SO hyper all the time (my cat, not the vet) Lol! And he's about 10 pounds and 6 months old. I have a hard time believeing he has feline herpes virus (they say they are supposed to be small framed and little and don't move much) He has 2 speeds, fast and faster. I don't think he knows he's sick! LOL.

He's probably the sweetest of my ten. He talks, and talks....AND TALKS. AND TALKS! lol. I loves him =)

Thanks everyone for all your information. I appreciate it.

If your guy has herpes do NOT get the steroid shot. Steroids and herpes do not go together. Has he actually been tested for Herpes using the IDEXX Real PCR URD test? If not, you should consider getting him tested just to be sure he has it. If it turns out he doesn't, then you can look for other causes of the recurring "outbreaks". If he does have it, then you can really work out a plan to manage it and prevent or at least lessen future outbreaks.

My Hannah is FHV+ and she's on a maintenance amount of 500mg Lysine daily. She's currently fighting an outbreak, so she gets 1000mg/day. Not all herpes kitties are small, though. Some are bigger breeds such as ragdolls and Maine Coons.

Small framed? Lol - my herpes boy is an 18lb Ragdoll I am not sure why your vet is telling you to give him Steroids? Steroids pretty much stops the immune system, which is the last thing you want to do during a flare up... Are you maybe talking about antibiotics? In kittens sometimes vets give antibiotics during bad flare ups to prevent opportunistic infections...

Bugsy had to take Steroids a few times due to other issues and it does not go well with Herpes... For him it was the lesser of two evils... But specially during a flare up, a cat needs it immune system to fight the virus and possible bacterial infections...

A steroid shot will not help a cat with herpes. Steroids depress the immune system which is the exact opposite of what you want in a herpes cat.

If his eyes look bad, he has most likely gone into secondary infection and needs antibiotics. Antibiotics do not cure, or affect the herpes virus at all. But they do cure the secondary infections that are common when a cat is younger and has less immunity to fighting infection.

Tolly's energy level was never affected by the herpes virus, except of course when he was so ill I thought he was going to have to lose his eye.

He's 11 years old now and plays as lively as a kitten every day. He's not small, in fact he is a big boned cat, and could easily weigh 11 or 12 pounds and still not be fat, but he's always been on the thin side (9 pounds)

Herpes manifests differently in each cat, but l-lysine is the best treatment for controlling outbreaks. As your kitten gets older he will probably have fewer and fewer occasions when the virus goes into secondary infection.

Keep stress at a minimum is very important.

Let us know how he's doing.

I agree with the advice you've gotten so far! I also have a girl with FHV. I give her (and my other 3 cats) at least 500mg of Lysine every day with their food. They are also on a grain free diet, because many grains are high in Arginine which is the amino acid that the herpes virus uses to replicate. But, like other posters have said, Lysine is probably the best thing you can use to keep herpes at bay.

Flare ups can be caused by many factors, including stress, seasonal changes, etc...and in the event of a flare up you should double the Lysine dose until the flare is over.

Definitely stay away from steroids - they can cause a herpes flare up or if your kitten is already having a flare up, steroids will probably make it worse!

Best of luck with your new kitten!

I had no idea about steroids and herpes, and was interested to read the explanation here.... how I wish I had known that while Bunnelina was still alive. I've learned SO MUCH important information on this site. I only wish I'd gotten here sooner!

My one cat is suspected of having herpes (did not do blood test to confirm).. she responds well to the L-Lysine tho. She was pretty down one nite, but she perked up quite a bit the next day.

She is certainly not small framed! She weighs about 16 pds.. actually when I took her in to the vet for her shots a few weeks ago, the vet pointed out that she gained a little weight since the last visit, and the vet commented that she must had the same problem he has!

Would some weight loss help at all?

She is at least 4 or 5 years old, and the first time she had an issue was last year.. it was shortly after Bastet came into the household. All of the cats were sneezing a little, but she took it the hardest. She had an issue again this year shortly after recieving vaccines.. I dont know if its seasonal or stress related? None of the other cats seem to be having any problems.

I dont keep the cats on the L-Lysine all the time.. should I? The vet did not really give instructions on using it all the time, I was under the assumption that it was only needed when there was an issue.

I would keep a cat with a known herpes virus on a maintenance dose of l-lysine all the time. It can't hurt for all the cats to be on it, it's an amino acid and helps boost the immune system.

I know some vets say only use "as needed" and perhaps some cats only need it taken in that way. Tolly needs to be on the maintenance dose, if he is taken off it all together, the flare ups come back.

When I had the h1n1 last fall I started dosing all my cats with l-lysine to keep their immune systems in top shape, while I was contagious.

herpes is not diagnosed with a blood test. It is done with a swab, a numbing drop is put in the eye, and the vet goes deep with the swab and gets a good sample of material from the eye. What the test actually entails I don't know, but it's quick and relatively inexpensive, at least it was the last time I had it done. (8 years ago)

Stress and seasonal changes are what most often will bring on a flare up, in my experience.

I had seen people suggest the test "if you have the extra money" .. so I assumed it was a costly test.

If its not that costly then- should I have all the cats tested? Or would a test only work if the cat is having a flare up?

I may keep them on the l-lysine all year then. Its not that expensive. I think the tub we have cost $15 or $20, and it lasts a long time.

My BF put a little on some tuna and tried to get Tabbi to eat it the nite she was really sick, and she just wasnt interested.. he was going to divide it up to the other pets so it wouldnt go to waste. He asked if it was OK if the dog had it, since it had the powder.. I didnt really know the correct answer to that, so I told him to give it to just the cats, since I know it wont harm them to get the powder.
