Felisyl Immune System Support for Cats is a safe nutritional supplement for your cat if it has a condition that is responsive to L-lysine. L-lysine has been known to reduce the harshness and number of occurrences of herpes simplex viral infections. These infections result in fever blisters and cold sores. L-lysine is an effective ingredient of Felisyl Immune System Support for Cats.

In cats, the herpes virus is considered very contagious. What makes it so problematic is that it is a very common cause of upper respiratory infections (URIs). Symptoms of URIs include eye discharge and sinus congestion in your cat. You may also notice some squinting of the eyes and sneezing as part of the effects of an upper respiratory infection. Felisyl Immune System Support for Cats can help.

Felisyl is an easy to use nutritional supplement that kittens and cats alike seem to find tasty. It is easy to administer by simply mixing it in with their cat food.

Other benefits to Felisyl Immune System Support for Cats are that it helps promote healthy tissue, encourages respiratory health, and can even help with your catís vision. It is effective, easy to administer, and has some nice additional healthy side effects.

Usage Information

The Impact of Feline Herpes Virus on Your Cat

What is the Feline Herpes Virus?

The Feline Herpes Virus causes an acute respiratory illness known as Rhinotracheitis. The virus affects domestic and wild cats worldwide. Rhinotracheitis, a member of the feline upper respiratory infection complex, is one of many viral and bacterial infections that cause sneezing and discharge from the eyes and nose. Cats often have two or more of these respiratory infections at the same time with FHV-1 being the most common.

Where does the virus typically originate?

Cats of all ages and breeds are susceptible to FHV-1. Certain factors increase the likelihood:
  • Kittens born from infected mothers
  • Multi-cat households, catteries, and pet adoption centers with the following factors:
    o Overcrowding
    o Physical or psychological stress
    o Poor nutrition
    o Poor sanitation
    o Poor ventilation
  • Lactating pregnant cats
  • Sick cats, particularly those with a weakened immune system or other respiratory infection
  • Unvaccinated cats

    How is the virus spread?

    FHV-1 is spread through the discharge from an infected felineís eyes, nose and mouth. The most common methods of transmission are when contact with contaminated objects that an infected cat has touched or sneezed on includes cages, food, water bowls, litter trays, etc. Several days of close contact are necessary for infection to occur. Most cats that are infected with FHV-1 are never completely rid of the virus and are known as latent carriers. Latent carriers do not necessarily show symptoms but harbor the virus in nerve cells.

    What are the signs and symptoms?

    Common symptoms include:
  • Coughing
  • Fever (up to 106⁰ or 41⁰C)
  • Loss of appetite and weight loss (anorexia)
  • Runny nose (rhinitis)
  • Sneezing attacks
  • Runny eyes

    How is the virus diagnosed?

    FHV-1 is diagnosed on the basis of clinical symptoms and the catís medical history. Lab tests detect the virus in the catís nasal or eye secretions. It is strongly recommended that your cat visits your veterinarian on a regular basis. If any of the symptoms are exhibited by your cat, immediate veterinarian attention is advised.

    How can the virus be treated?

    Prevention is the best method to keeping FHV-1 from infecting your cat.
  • Stress reduction: make sure the room is warm, well-ventilated and adequate lighting. Keeping the cat indoors is recommended by veterinarians.
  • Healthy diet: make sure your cat is eating and drinking enough.
  • Keep the catís eyes and nose clean and clear of discharge.
  • Use a humidifier or place your cat in the bathroom while a hot shower is running to help breakup the mucus in the upper airway.
  • Kittens should be vaccinated at 8-10 weeks of age, then at 12-14 weeks, and then annually.

    Once infected, most cats are not completely rid of the feline herpes virus. These latent carriers can benefit from products like Felisyl, an immune system support supplement. Felisyl by Pet Health Solutions is a brand new nutritional supplement that is safe and effective for conditions responsive to Lysine. Lysine has been proven to reduce the severity and duration of feline herpes virus infections. Felisyl is a palatable oral powder that easily mixes into your catís food to provide relief from FHV-1 flare-ups. Felisyl rivals competitive feline Lysine products with equal effectiveness at a fraction of the cost.

    Only product to help my pet. by Buddy from Jackson, TN08/21/2013

    This is recommened by my vet. Only thing that can build his imm. system

    Felisyl by Sandy from New York12/14/2012

    Used the product for my cats who were sneezing and it seemed to help them a bit. Their eyes are no longer dripping as they were, so perhaps it works as stated.

    by Barb12/03/2011

    I give this to my 4 cats on a daily basis. Very pleased with results.

    Felisyl Immune System Support by Queen B from New Castle, DE11/23/2012

    It seems to work as well as other brands. It dissolves better in food than other brands. It's slightly cheaper, however, I believe the dose is slightly larger.

    my cats love this by Karen11/30/2012

    this product is very palatable, one of my cats even tries to lick it right out of the jar!

    Good product! by FosterMama from Boston09/24/2013

    Easy to give to kitties with a little bit of wet food or even add a little water. My cats love it and it keeps their sniffley episodes down. Love it!

    My Ferals Like It by kirvls from Colorado09/17/2013

    They like the flavor and it gives them the Lysine they need.

    Felisyl by Pam from Enuclaw, Wa03/15/2012

    This product helped my cat conquer his sinus condition better than a whole series of antibiotics. It seemed to greatly improve his immune system.

    Felisyl by jj05/20/2013

    works really great it really helped and looking forward to ordering more in the future

    Not the answer by Pauladimi from Las Vegas Nevada02/26/2013

    I have cat with diabetes and allergies. it does not help him at all. I was hoping to avoid going to the vet and getting him a steroid shot

    by from 03/04/2012

    My cat does not like "treats" so I bought the powder version of Felisyl and put it in his food. He does not know the difference and he eats it! YEAH!!! No force feeding!!!! Something you do not want to do with a cat. (CLAWS)

    be by buyng from moreI


    by Benji's mom03/04/2012

    The cat loves his food with sprinkles of FeliSyl on top and has zero hair balls if given daily.

    product probably fine but the cat won't get near i by max's mom from west palm beach04/05/2012

    They say it is flavorless and odorless. The cat doesn't think so. Right now I am back to crushing human lysine tabs and then mixing them into soft food to hide it. Right now, that is fine but may try sneaking this into his soft food again soon to save me the trouble of mashing his pills. Too early to tell how this will work.

    Kitties Are Crazy for It! by foxfyreutk from Tennessee12/31/2013

    I had been mixing granules into canned cat food, but that is a very expensive treat. Thought I would try the kitty treat version. Both my cats are crazy for it. They try to open the bag themselves and remind me it's time for their treat. Far easier and not nearly as expensive as the powder.

    ease of use by Query11/29/2013

    So can I just add this to dry food left out for self feed of 1 to 16 cats?

    it works great by cathy from indiana08/20/2013

    my cats caught the feline cold from a new cat I got they were all sick. I looked up what to give them to help them. this is the lysine and its in this product works great to keep it under control, nobody has gotten sick again . I put it in there food and they don't even know they are eating it.

    Good product by Dawn from New York, NY03/10/2012

    I used to buy a more expensive brand, then found this one. The color turned me off a little (I'm used to a white powder), but my cat doesn't know the difference and I have no problem putting it in her food.

    by Katzhse from Tucson, Az11/24/2012

    I have been sprinkling this on their dry food so at least they get some when they eat. If i put it in the wet food they won't eat it.

    oral powder by Anita10/24/2012

    This works well mixed with wet food...we do have a couple that will eat it right out of the bowl before the food is added....it does a good job of helping to control virus'

    FABULOUS Felisyl L-Lysine Granules by iluvcats from Louisiana01/22/2015

    This product is EXACTLY what I have been needing for my two kitties! These granules have proven to be the very BEST product to deliver the 250 mg of L-lysine necessary for my cats health needs. I was using the L-Lysine in a pump, which is tuna flavored. The extra strong smell seemed to be a deterrent, even though they both love seafood flavored wet food. They would walk away and leave the food to spoil, causing me to have to open another can of food. When one of my cats recently had a herpes breakout (sniffles & runny eyes) I had to put the stinky tuna flavored thick L-lysine from the pump on my finger and stick it in her mouth to insure that she was being treated properly. The granules don't have a scent; both of my cats lap up their wet food; and my sweet kitty is now 100% well in less than 2 weeks! Like normal, I put the wet food in the bowl with water; mix it up; then put the tiny scoop of L-lysine granules on top; gently stir so that the granules are just barely mixed in - they lap it up and get 100% of this vital nutrient! I HIGHLY recommend this product! It is AWESOME!!

    Good stuff! by Kaye6311/13/2012

    My cats loved this and I will be ordering it again!

    Works very well by moms_2slow from Wilton, CA08/16/2012

    This product has a very yeasty smell, so my cat loves it. He has slowly improved on the product, so I am quite happy.

    Great product by Bruiser04/13/2014

    When shopping for a Lysine supplement for my FIV positive cat I had been used to the Viralys gel. Seeing as how the Felisyl brand was half the price I thought I'd give it a go. I feel that the powder allows me to be more accurate in the dosage. And my cat has transitioned very well. I will definitely be back for more when my supply runs out.
