Feline Herpes Virus

What is feline herpes virus
Feline herpes virus is an upper respiratory virus of cats. It is also known as rhinotracheitis virus. It is very common among cats, especially in environments where there are multiple cats or new cats are constantly interacting. The virus is spread through the air and replicates in the upper respiratory tract (nasal area, tonsils). The conjunctiva of the eye is also affected during the primary infection. Clinical signs of infection include sneezing and ocular and nasal discharge. In most cases the primary infection resolves with no residual ocular lesions. However, depending on the age when the cat is affected, the serotype of the virus (infectivity or strength of infection), and other factors, there may be various ocular signs. In very young cats, adhesions of the eyelids to each other or to the cornea may occur. Adult cats may experience recurrent conjunctivitis or corneal ulcers. The virus remains latent in the nerves that serve the eyes. When a cat is stressed or exposed to new serotypes (different strains) of herpes virus, the ocular disease can recur. There is some evidence that eosinophilic keratitis, plasmacytic-lymphocytic keratitis, corneal sequestrum, and some cases of anterior uveitis may be associated with feline herpes virus infection.

How do cats get feline herpes virus
Most cats are affected as kittens, contracting the infection from their mothers. Stray cats, multi-cat households, and cats from households where new cats are constantly introduced are more likely to suffer infection. Feline herpes virus is not contagious to dogs or to humans but only affects cats.

How is feline herpes virus diagnosed
History and clinical signs can diagnose ocular diseases caused by feline herpes virus. Aside from history and clinical signs, diagnostic tests for feline herpes virus include virus isolation, immunofluorescent antibody testing, polymerase chain reaction testing, serology, and cytology. Testing can be expensive and is generally reserved for specific cases. Tests that may not specifically detect the presence of herpes may be used to detect ocular disease caused by herpes. These tests include a Schirmer tear test (measuring tear production), corneal staining, and conjunctival biopsy.

How is feline herpes virus treated
Treatment for feline herpes virus infections is nonspecific and generally directed at controlling secondary bacterial infection. A topical antibiotic such as tetracycline or erythromycin may be prescribed for use in the eye. Systemic antibiotics may also be prescribed. Oral L-Lysine is recommended by many veterinary ophthalmologists at a dose of 250-500 mg twice daily. Lysine competes with another amino acid, arginine, that herpes virus must have in order to reproduce. Lysine has been demonstrated to decrease the severity of ocular symptoms associated with herpes virus infection (1) and reduce viral shedding during periods of disease recurrence (2). Depending on symptoms, other medications such as topical antiviral drugs, topical polysulfated glycosaminoglycans, topical nonsteroidal anti-inflammatory drugs or topical interferon may be used. In some cases the ocular diseases resulting from feline herpes virus may require surgical intervention. The key to managing the clinical signs associated with feline herpes virus is controlling the cat's environment. Cats exposed to multiple cats (indoor-outdoor cats), cats in multiple cat households, or cats that are frequently introduced to new cats are difficult to keep disease free. Reducing stress by maintaining a stable routine is helpful in preventing recurrences of disease. Keep in mind that it is the nature of the virus to see recurrences of the disease and periodic treatment is often necessary.

We adopted a 2 year old female cat named Sky. We now call her Gray C.Sky, she is a fancy girl, she is a Chartreux (well most of her anyway)from a shelter. She was held in the sick kitty room with an upper respiratory but we were told she was fine. No sooner I bring her home that she sneezed around 20 times. This goes on for weeks along with one watery eye and mucus. I have had many cats in my life and never experienced this. After a couple of months a vet diagnosed her with feline herpes. She was put on 20 days of antibiotic and then it was suggested that I give her viralys. Well little Gray C. is doing much better sneezes are down to once in a while,no mucus and her eye get glassy only when she does sneeze. She is the sweetest cat I have ever had I put the Viralys on my finger tip and put it directly on her tongue. I would recommend this product for sure.

My cats are doing better, which is a good thing after over $1000.00 and having to put one down we were ready and willing to try anythinh, our Vet is the best and so is this

Our kitten Max really likes it and it has helped with his runny nose. It was really plugged up but now it is a lot better.

This product is so much easier to use than grinding up tablets. it is worth the price as my cat eats it when mixed with wet food and a little water.

My Ragdoll kitten is being treated for idiopathic uveitis. The eye clinic charges $34 for L-Lysine gel, which is part of his treatment. I get 2 bottles of it here for less than the price of 1 bottle at the eye clinic! I am so relieved that PetsTruly offers this product. Great service, great selection, fast shipping. Couldn`t be better.

My cat pepper has running eyes caused by the herpes virus.There is no cure as yet so the only help available is to supplement her diet with L-Lysine.The best way for us to do this has been the tube of gel.She hates the powder.But she needs no coaxing to take her meds when it is in the gel form.I put a small amount on my finger and she licks it off.Wash my hands and job done.

Excellent service and exactly the product as described on your website. Thank You

Thanks PetsTruly for your fast service and great product. Viralys L-Lysine is `just what the doctor ordered` in clearing up watery eyes in my new little Siberian Forest ckitten. I will definitely go to your website in the future when I need high quality products at a great price.

First of all, the price and service from Petstruly were both great. I have nine cats and use both the powder and gel Viralys L-Lysine so it can get quite expensive. I like the gel for those who are picky eaters or don`t like wet food. Just put a dab on the nose and they are good to go. Three of the cats have had watery eyes for years and now that problem has all but disappeared. Even the Persian`s eyes have cleared up. The minute I start to hear sneezing, out comes the Viralys and it hasn`t failed me yet. My vet told me to keep using it as all of the cats are doing great.

Great service from Petstruly. I give this to my kitten by first squirting some Viralys into an old pill bottle. Then I use a vete ary syringe to suck the right amount out of the pill bottle and into the syringe. Its very easy to squirt into her mouth and she doesn`t mind the taste at all.

The product arrived promptly. It is easy to use and the cat doesn`t hate it. Seems to be helping his eyes.Price is very fair.

Web-site was user friendly and additionally informative Price was favorably competitive. I promptly received confirmation , quickly followed by actual shipment. This company has the products and efficient service to substantiate eager re-orders. Thanks

Great product and great service.

I am always VERY skeptical when a product says `delicious` or claims that cats will eat it up. I`ve been around the world with products that made that claim only to find that it is not only untrue but I`ve had cats actually run the other way when they smelled it coming! Viralys was recommended for an outbreak in our house and I have to say that I was amazed at the way the cats go for it. I simply spread it on the top side of their paw and they lick it right off. The funniest part is to watch the younger ones try to get at their siblings` paws to lick off the siblings` dose too! It has also really helped with the herpes virus symptoms which is a blessing because we raise Himalayans and their smushed little noses just can`t stand much congestion at all before things get critical. Thanks for offering this great product!

Very potent and effective at reducing herpes symptoms in my cat. She gets brown watery stuff that comes out of her tear ducts. It`s kind of yukky. This stuff has made that go away. I give her the recommended dose in a medicine syringe. I have to make her swallow it and she doesn`t like the stuff that much. She doesn`t like the taste of it. I wish they made it in a better flavor that most cats would like, but you never know with cats, they are very finicky little animals. This stuff really works. I just wish my cat liked the flavor.

For CottageKitty, Have you tried a tiny bit of light tuna? My vete arian said a small amout is ok to give to your cat about 1/2 teaspoon. My cat will not eat wet cat food either but does like human canned Lt. tuna. or White. Also white chicken. You could grind up the white chicken and put the powder on that maybe.

My cat tolerates this very well. I couldn`t get him to take any other type, and after 3 weeks, I see an improvement. My vet told me it could take 2 months for him to clear up. I open his mouth and rub the dose on his tongue, then follow with a treat.

This product is a blessing! Thank goodness my vet recommended it. My cat has only 1 minor flareup (she gets the terrible respiratory symptoms) in the past year, and that was much more mild, since we started this. And a small price to pay to help keep her healthy. She usually licks her dose right out of my hand. If not, I rub it on her front paw and she licks it right up. Thank you for saving us!

I give a small amount of this gel to my cat as needed on her nose, and she licks it off. It seems to help with her watery eyes, and this way I don`t end up giving it to my other cats.

I`m so glad we finally found something that has benefited our cat! She has suffered all of her life with nose problems and now she is so much better. Our precious `little one` is now about 8 years old, is about 11 pounds, and is an all black American short-hair we got from the pound when she was a small kitten. When it gets cold or if she even gets a slight chill at night, her nose will swell and she will sneeze out large amounts of thick green mucous with blood. At first while she was younger it was about 4 months out of the year (winter mostly) when she was `sick`, but now the time was getting shorter and shorter between infections, even in the summer. It looked like she was always fighting an infection and her fur was dirty all the time. The previous vet said maybe it was allergies (maybe to us, her food, litter, etc. etc...we changed everything that we could to find the problem), but we got a new vet that did some blood work (yes it was expensive but worth it) and said it was feline herpes. The vet said to give her Lysine but sadly she will never get better. I started her on this product about two weeks ago (winter - middle of Jan. `09). After the first treatment she began to get better in about three days. Unfortunately, one day I was not able to give our cat her meds and the next day her nose was a little runny, but clear. So far her nose has improved dramatically. The swelling around the bridge of the nose has decreased, she is not breathing from her mouth anymore, her fur is super soft and glossy, and overall she`s in a much, much better mood. Also, along with the Lysine we purchased (about three months ago) an automatic cat bed that will warm up when she is in it, but not while she is out. It was about $60.00-ish, but worth every penny. The combination has really worked for our precious one, but it was the Lysine that really did the job. For some reason the feline herpes virus tends to make cats feel cold all the time. Now she spends about 85% of the time (or more depending on how cold it is) in it. We have no other animals and she is completely an indoor cat. When they say `keep stress down` they mean it. Any-little-thing will set off another infection. For example, if my husband and I have been gone to long (for the day) or if she feels we are in any way stressed, she will chew the tip of her tail off and `snort` for attention. We (the cat and I) would argue about the bathroom door being closed but when she was really sick, the cat would meow/howl like she was in pain, ... and so would win the argument. I give her the recommend dosage for an adult cat by scruffing and a syringe. Just unscrew the top of the tube and insert the syringe like a regular injection, but without the needle. Our cat really hates to be scruffed, but it`s the only way we can give it to her. She will not eat wet food, so the powder kind is out. Luckily, she likes the taste and will eat small amounts on her own, but just not enough for a full days dose. My only complaint would be I wish it could be in a different form. Maybe a once a month/week sub.Q injection someday? Or maybe DRY cat food already made with it? Anything besides scruffing daily would be nice. For her and for us. But at least for now she`s feeling much better and will gracefully let me win the argument then go scratch the couch up.
