Ingredients L-Lysine Hydrochloride Directions See Label Review: Has vastly improved my housecat's drippy nose and sneezing - Having spent 2K on seeing 5 vets over four months, this appears to have massively reduced my cat's drippy nose and sneezing and she can now obviously smell more, and as a result, is less of a fussy eater. The vets reached the point where they could offer no more help, other than perhaps a referral for a CT scan, etc. but as my cat was basically otherwise well, and she chooses to remain indoors, this felt unnecessary. We did agree to an anaesthetic and nasal camera, which reassured us that polyps/growths appear unlikely, so before going down that route, I would thoroughly recommend giving this a try. Within 5 days of just a teeny amount in her food, once a day, there was a massive improvement. Review: Good for reducing cat flu symptoms - Our cat was struggling with cat flu and so we took her to the vet. A two week course of antibiotics was prescribed, but by the end of the two weeks she was still clearly struggling - sneezing, dribbling, mouth ulcers, overcleaning front and back paws, and conjunctivitis. She was in considerable stress and I didn't think she would survive. Out of desperation, I checked many on-line reviews of this product, and they were mostly very positive, so I purchased a jar of the l-lysin. Our cat's health has improved immensely and she's pretty much back to her normal happy self with bags of energy. I use the product now every day for all four of my cats - just a very light sprinkling on their wet food, and they still eat it. So, I would definitely recommend this product. ## Features - Perfect for use in cats only - Helps support a healthy immune system - Also helps support normal respiratory health ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B016WG7UF8 | | Active Ingredients | None.No artificial flavors, colors or | | Active ingredients | None.No artificial flavors, colors or | | Best Sellers Rank | 64,048 in Health & Personal Care ( See Top 100 in Health & Personal Care ) 32 in L-Lysine Nutritional Supplements | | Brand | NOW | | Brand Name | NOW | | Country Of Origin | USA | | Customer Reviews | 4.5 out of 5 stars 3,460 Reviews | | Flavour | Nope | | Global Trade Identification Number | 00733739044501 | | Item Form | Powder | | Item Type Name | Pets, L-Lysine for Cats - 226g | | Item Volume | 0.62 Millilitres | | Item Weight | 0.64 Pounds | | Item form | Powder | | Item volume | 0.62 Millilitres | | Item weight | 0.64 Pounds | | Manufacturer | NOW Foods | | Manufacturer Part Number | 4450 | | Model Number | 4450 | | Number of Items | 1 | | Product Warranty | See Label | | Protein | 0 Portion(s) | | Target Species | Cat | | UPC | 733739044501 | | Unit Count | 226.8 gram | ## Product Details - **Active ingredients:** None.No artificial flavors, colors or - **Brand:** NOW - **Flavour:** Nope - **Item form:** Powder - **Item weight:** 290 g ## Images ![L-Lysine Powder for Cats - Image 1](https://m.media-amazon.com/images/I/71XDv3QInAL.jpg) ![L-Lysine Powder for Cats - Image 2](https://m.media-amazon.com/images/I/71RIn-RjSBL.jpg) ![L-Lysine Powder for Cats - Image 3](https://m.media-amazon.com/images/I/31Hx+6SxUlL.jpg) ![L-Lysine Powder for Cats - Image 4](https://m.media-amazon.com/images/I/71z5aR5okqL.jpg) ![L-Lysine Powder for Cats - Image 5](https://m.media-amazon.com/images/I/71+PwabNaYL.jpg) ## Questions & Answers **Q: Amazon needs to show the label's ingredients so is it pure L-Lysine no fillers or additives? Thank you.** A: No fillers or additives, so it is pure L-Lysine. And to be honest when I bought the flavored powder L-Lysine made specifically for cats (different brand)- I was able to see a white powder in jar and a few streaks of tan powder- it didn't stay mixed well and the tan powder was the added flavoring. This product is white granules. I mix it in with canned food- the added flavorings I was paying A LOT extra for was never needed and I was so glad when I switched to buying from Now brands, definitely a money saver. **Q: Why does directions say twice weekly? I thought twice daily.** A: Directions say--cats 6 months and older-1/8 teaspoon twice weekly. Kittens 6 months and younger -1/16 teaspoon twice weekly.. My cat was not eating for three days and would hide under the bed. After two days of this stuff he started to come around. Now hes back to his old self. I gave him a pinch twicw a day the first week because he was so bad, now im going with the directions. Good luck,,,cap **Q: How to the feed ration?** A: I just mix it in with the cat's food.These are the manufacturer directions:* For cats 6 months or older 1/8 teaspoon twice daily* For kittens under 6 months 1/16 teaspoon twice daily **Q: Why does this product have a california proposition 65 warning?** A: California does not include pet products in Prop 65. NOW does not add this warning, but some resellers add a warning for all products sold to California businesses or residents to assure compliance with that unique law in case manufacturers aren’t testing heavy metals; NOW does this testing. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Has vastly improved my housecat's drippy nose and sneezing *by A***R on 24 September 2024* Having spent 2K on seeing 5 vets over four months, this appears to have massively reduced my cat's drippy nose and sneezing and she can now obviously smell more, and as a result, is less of a fussy eater.

My cat has had 2 bouts of runny nose/sneezing (expensive vet visits) He hasn`t had another flare up while I`ve been using this, so will have to wait and see if it reduces his symptoms/length of flare up. He happily eats it mixed in with Lick - e - Lix, and there isn`t any strong smell to put him off ## Frequently Bought Together - NOW Foods Pet Health, L-Lysine Supplement, Powder, Formulated for Cats, NASC Certified, 8-Ounce - Purina Pro Plan Veterinary Supplements FortiFlora Cat Probiotic Supplement for Cats with Diarrhea - 30 ct.
