Our 15 year old cat is thriving!

Without our giving this probiotic to our senior cat, I'm not sure what his state of health would be. We and he depend on it for his health and well-being. We credit this liquid cat probiotic with giving him an extra lease on life. Thank you!

Love it!

Great product

Since putting this probiotic in my cats’ food I feel that they are not vomiting as much. In fact, hardly at all. Thank you.

Love it!

I love this cat probiotic. My vet gave my cat a generic one for both dogs and cats which contained some ingredients cats don't need. After some research I landed on this one from Mary's Organics made exclusively for cats. Easy to administer, just a couple squirts on her food and she's good to go!

I hope it helps

I give this to my cat in the evening. I always need to start him out low and slow on probiotics and I like this one because I can titrate his dose according to his response. Right now he is up to 2 drops. I also like that I don't need a prescription.

Have A Question? Great, Ask Us!

Really. We are here to answer any question you may have.

Can I put the probiotic in my cat’s food?

Yes, the probiotics can be added to wet food or dry food, or to their water. Some customers tell us they have success giving it to their cat directly. Feel free to try whatever works best for you and your cat.
