## Questions & Answers

**Q: I don't feed my cats canned food.  Will this work on dry food?  If so, how do you do it?  Do you wet it at all?**
A: This product will work well when added to canned food.  Cats should Never be fed dry food only.  Dry food does not contain enough water to maintain a cat's health.  Dry food is made for people and not cats.  It is made to be convenient.  Cats are desert animals and will not drink enough water on their own.  Cats need all the water you can get into them, to avoid long term health problems such as diabetes and the dreaded kidney disease.  Canned food is more like the prey cats would eat in the wild and has enough water to maintain the cat's health.  I also add water to the canned food.  Complete info on this can be found on the Cat Info website, written by Lisa Pierson DVM.

**Q: Approximately how many servings are in a container?**
A: Depends on the size of your serving. The recommended dose for adult cats is 1000 mg. per day (2 scoops) so...that would be 100 days (2 servings/day) per container. I however, give 1/2 that amount to my cats very successfully. 500 mg.(1 scoop) which means there are 200 doses (servings)or 200 days per container.

**Q: Can this product be added to water?**
A: I cut up can food and add a little warm water to make a gravy. I sprinkle the Lysine powder on food and wet it with gravy. My vet said a little extra water is good for cats. They love it. I have not used this product with plain water.

**Q: Where is this product made? Is any part of it made in China, or does any part come from China?**
A: No part comes from China - except maybe the container. You can compare this product to the one offered by vets under the name "Viralys" by Vetoquinol, an acquired Company of Tomlyn Products. The only difference: THE PRICE at my vet is $ 39.--. Both are made in Canada.

### ⭐⭐⭐⭐⭐ Review
*by M***S on 18 November 2014*

I purchased this as a replacement for another brand (Viralys) that I had been getting through my vet. One of our kitties had a "cold" when we adopted her. That "cold" just wouldn't clear up. She had a weepy eye and sneezles for weeks. When we took her to the vet, the vet said it was kitty herpes and prescribed the Viralys (at $30 a container). It's l-lysine in powder form; you sprinkle it on the cat food. There is no cure for feline herpes, but l-lysine helps clear up the symptoms. (For those who want to know how l-lysine helps, The Cat Doctor & Friends in Santa Clarita says, "We use L-Lysine to fool your cat's herpes virus into self-destructing by using L-Lysine, instead of another amino acid Arginine, when making new copies of itself. This decreases the amount of herpes virus in your cat's body and hopefully eliminates clinical signs such as sneezing or squinting one eye and reddish brown discharge. Green or yellow discharge from your cat's eye or nose is probably not feline herpes and deserves a veterinary visit.") The Viralys l-lysine powder not only worked great, clearing up the weepy eye and drippy nose within a remarkably short amount of time, it was also loved by all our kitties. (The vet said it wouldn't hurt any of them to eat it.) However, at $30 a container, and with the stupid mistake I made that wasted half a container (see below), I wanted to find a less expensive alternative. And I did. This product, the Tomlyn Scientifics l-lysine, seems to be identical to the Viralys, and costs half what my vet was charging me. My one concern was whether it would taste as good to the kitties, and it does indeed seem to. == My Stupid Mistake and How You Can Avoid It == When I first got the Viralys from my vet, I made a stupid mistake. I used the little scoop that comes with the powder to sprinkle the lysine powder on the cat food, and then I used the scoop to stir the powder into the food. Then I returned the scoop to the container. Those of you who are familiar with good sanitation practices will be able to predict what happened next: after a while, the tiny crumbs of cat food I had inadvertently transferred to the container gave birth to new life. In a few weeks, I saw suspicious little clumps and balls in the powder. I threw out the rest of the powder rather than risk making my kitties sick. After thinking about what I could do to prevent wasting my kitties' medicine (and my money), I realized the solution: put the powder into a shaker container so it never gets contaminated. After shopping around, I purchased the Kaiser Bakeware La Forme Select Sugar/Spice Shaker Set (available here on Amazon), which is just the right size for the powder. I'm using the shaker lid with the largest holes. Now all is well.
