"The powder is easy to mix into food, and my cat takes it without any issues. I like that it provides lysine to support immune health and overall wellness. The quality seems excellent, and it’s very convenient for daily use. Definitely a product I would purchase again!"
"Before trying Lysine for Cats, I had no idea how essential lysine is to support my fur babies immune function and metabolism! I've since learned that lysine is an essential amino acid and cats need it to build protein just like humans! My cats are VERY picky eaters, but they had no issue with this blend! It is a (daily) easy-to-mix powder & I keep it with their treats."
"I wasn't sure what to expect from this Lysine powder, but I was pleasantly surprised that all five of my cats would go looking for the dry food pieces that had the powder on it! And adding the powder to their food was easy to add to our routine. I just keep the container and measuring spoon next to the food, sprinkle it on top in morning, and that's it. So easy, and I feel good knowing I'm giving my cats something that supports their immune system! I'd recommend to anyone who's looking for ways to round out their cats diet, since Lysine is an essential amino acid that cats have to get from their food."
"As a veterinary technician, I'm always thoughtful about the products I choose for my own pets, so I was excited to try Carlson Labs Lysine Cat Powder with my cat, Ralph. What I like most is how easy it is to incorporate into our daily routine. I simply mix the powder into his food once daily. My cat had no problem eating it, which is always a big plus. I appreciate that it's a simple addition to our everyday routine, and I like knowing I'm choosing a product from a brand I trust. As someone who spends every day educating pet owners about supporting their pets' overall wellness, I know that small, consistent habits can make a difference in caring for our four legged family members. Overall, I've had a great experience with Carlson Labs Lysine Cat Powder, and it's been an easy addition to our routine. I'll definitely continue keeping it on hand for Ralph!"
"Carlson Labs Lysine Powder has been an easy addition to my cats’ daily routine. It mixes well into wet food, and even my picky eaters don’t seem to notice it’s there. I love that it’s a simple way to provide extra immune support, and it’s been a great addition to their overall wellness routine."
"I’ve been really happy with this lysine powder for my cat! It’s easy to mix into his food, and he doesn’t seem to notice it’s there. Since adding it to his routine, I’ve been impressed with how simple it is to support his immune health. The powder blends well, the container lasts a while, and I appreciate the quality ingredients. Definitely a great addition to our daily routine, and I’d recommend it to other cat parents looking for an easy immune support supplement."
"I've been giving my cats some of this for over two weeks now. I was worried about what they'd pick up now that they can go outside whenever they want. I just sprinkle some on their food in the morning and they gobble it right up! I don't even have to mix it in, it doesn't smell bad to them so they just eat it! I appreciate how easy it is and how I know I'm boosting their immune system with this simple habit. I also like that the Lysine is sourced sustainably and aimed specifically for cats and their health. My cats seem healthy, happy and their perky young selves. Thanks Carlson Labs!"
"My cat is overly picky and sniffs out anything we add to her food. This is the only thing I’ve seen her not notice in her food. The powder blends easily and has no smell."
"First and foremost, I love that my cat doesn’t even know he’s drinking his vitamins. Believe it or not, he can be quite the snoot when it comes to taking his vitamins. I feel so secure about my cat’s health since he started taking this supplement. He’s been on it for a few weeks now and he’s taken it so well! I honestly had no idea how important Lysine was for cats to support their immune function and metabolism! And on top of it all, it’s easy to mix with his food and doesn’t cost an arm and a leg! I will continue restocking this for my fur baby!"
"My cat has been through more than ten different foods and supplements over the years, so I've gotten used to the routine of buying something, having her sniff it once, and walking away. It's been about two weeks now, and her eyes look clearer and she's been sneezing less than she was before I started - and mostly, she just seems more like herself. No downsides at all so far! If you have a cat you'd like to give a little extra immune support without turning feeding time into a battle, this is an easy one to recommend."
