B12 For Cats (1 fl. oz.) is THE product you didn't know your cat needed! It's a natural, bioavailable, non-synthetic vitamin B12 in liquid form and supports the health of your cat’s immune system, nervous system, digestive system & cognitive function. This B12 supplement is superbly more effective to cats than its synthetic counterpart, cyanocobalamin, because it is absorbed more readily by the body.

    I think it's okay for them.I just need to be careful how often I give it to em.I think a lower dose might be safer for now.They're still growing,so it's hard to tell if that's just them,or they are getting something from it.?Love ya Jackson...AWESOMENESS ALWAYS!

    Important part of daily regimen

    My cat Mary is nearly 11 years old. Her health was starting to take a downturn after the death of her companion kitty Maxi. She became at risk for kidney disease, overweight, skin and coat problems , anxiety and overgrooming, allergies, and UTI. I made a few select changes in her diet and added some supplements. I can’t speak to B12 results alone, but I know that she has made an incredible turn around with B12 a part of her daily diet. Her weight has normalized, her coat and skin have healed and is shiny and full, eye and respiratory problems managed, her kidney disease risk reversed, she is happier and more energetic than ever. Beyond that, it is a healthy energy, and not anxious as before. (I use B12 in combination with a balanced raw diet, Jackson Galaxy’s complete probiotics, omega-3, glucosamine joint supplement, and lysine immune support, antidepressant prescription, play and environmental enrichment)

    B-12 for chronic gastrointestinal issues

    My cat has been suffering from chronic gastrointestinal problems. Even prescribed vet diet cannot correct. My cat has frequent diarrhea, which last only a day or two. And occasionally occurs every few weeks. I am hoping that adding this B-12 into her diet might correct her tummy problems. Also, I added Happy Tummy supplement as well. It’s been a week now and so far so good!

    B12 for cats

    I have been giving my 16 year old Siamese your B12 daily since I got it. I add it to her wet food and she seems to accept it well. I don’t see much difference yet but will keep giving her 0.5 ml daily as suggested.

    Healthy kitties

    Having 6 cats is a huge responsibility and keeping them healthy is my goal. I give them this vitamin and i have notice that my babies are very healthy, always energetic. 2 of my cats have constant colds and allergies.. the b12 has helped with their constant sniffles and they have been doing so much better after taking this.
