As cats get older, their body can stop pulling B12 out of their food. Your Kitty can eat every bite and still miss it. Normal vet tests don't check for this. Changing her food won't fix it — food was never the problem. PetLovies drops give her the B12 her body isn't getting.

My cat Fig has been eating fine for 2 years but kept getting thinner. Tried a probiotic, vet said bloodwork was normal. I found PetLovies B12 drops and 6 weeks later she's the same weight she was last spring. My vet noticed at her last checkup and asked what I changed. I'm still a little shocked it was this simple.

I was skeptical because I already feed my cats expensive food. But my 9 year old Mochi was losing weight and I could feel her spine every time I picked her up. Started the B12 drops in her wet food, she doesn't even notice it's there. Within 1 month she stopped losing weight and started acting more like herself again. Wish I had found this sooner.

My vet kept telling me my cat was healthy but something felt off. He was eating every meal but just getting lighter and more tired. A friend recommended PetLovies and 4 weeks in the difference is noticeable. He actually meets me at the door again like he used to.
Why Your Cat Keeps Losing Weight
B12 is what your cat's body uses to turn food into energy. When B12 runs low the body cannot do that, so it takes energy from muscle instead. That is why the weight keeps dropping even when they eat every meal.
As cats get older they absorb less and less B12 from food. A regular vet blood test does not even test for this, which is why everything looks normal.
Why Liquid Drops Fix It
You cannot fix this with better food because the food was never the problem. The body just cannot absorb enough B12 from it anymore.
Pills and chews have the same problem because they still absorb through the same struggling gut lining.
Liquid cyanocobalamin is different. It goes directly through the gut wall without needing that lining at all. That is why it works when nothing else does. Half a dropper in their food once a day gives their body the one thing it has been missing.

"B12 deficiency is one of the most commonly missed nutritional issues I see in cats. The standard blood panel simply is not designed to catch it. A daily liquid B12 supplement is one of the simplest things an owner can do, especially for cats over 6 years old."
Frequently Asked Questions
Common questions we hear from customers
Does liquid B12 actually work for cats?
+
Yes. A 2024 clinical study showed that daily liquid B12 normalized levels in 100% of cats tested. The liquid form works because it absorbs directly through the gut wall, bypassing the part that is already struggling.
My cat eats fine but keeps losing weight. Could B12 be the reason?
+
This is exactly what B12 deficiency looks like. Without enough B12 the body cannot turn food into energy, so it takes energy from muscle instead. The cat eats every meal but the body cannot use it. That is why the weight keeps dropping.
My cat's bloodwork came back normal. Could they still have a B12 deficiency?
+
Yes. A standard vet blood test does not check for B12. It is a completely separate test. So a cat can have normal bloodwork and still be severely low on B12.
Is it safe to give every day forever?
+
Yes. B12 is water soluble so whatever the body does not need gets flushed out naturally. No buildup, no toxicity, completely safe for long term daily use.
How long until I see results?
+
Most owners notice their cat is more alert and present within 1 to 2 weeks. Weight usually stabilizes around week 3 to 4. Give it at least 4 weeks before deciding if it is working.
What if it does not work?
