Ingredients & Use

Lactobacillus acidophilus, L. plantarum, Bifidobacterium longum and Streptococcus thermophilus in an enzyme-enriched substrate with water and a proprietary blend of three organic grasses.

Suggested Use: Give the recommended dose to your cat in water, add to their food or serve directly into their mouth. Can be taken any time of the day.

Store in a cool, dry place. This Liquid Probiotic is easily absorbed and, unlike solid probiotics which are treated with heat and chemicals, our probiotics are always in their raw state, ensuring shelf stability & maximum potency.


Q: I’m not seeing a difference in my cat when taking this. Is it doing anything?
A: Yes, yet you may not notice any difference. Most of these changes can be strictly internal and show results in blood-work or better digestion.

Q: Can I put the probiotic in my cat’s food, or do I have to give it to my cat straight?
A: You can put the probiotics directly into wet or dry food, into their food or you can give them straight to your cat. Whatever works best for you and your cat.

Q: Are the strains of bacteria in here the same as humans or are they for cats?
A: Our Cat Probiotic has four strains: Lactobacillus acidophilus, L. plantarum, Bifidobacterium longum, and Streptococcus thermophilus. While this product is human-grade quality, these strains are the best suited for felines and are shown to maintain and enhance the natural microflora of cats.

Cat probiotic

My beloved ragdoll had Lost a great deal of weight, was not eating, and when he did eat, he would throw it back up. Only 4 1/2 years old, pampered and babied in every way, I was baffled how to help him. I did some research and came across Mary Ruth probiotic for cats. Since he was throwing up daily, I felt I really didn’t have anything to lose. I am not a vet, I have no medical background, but I will tell you this product has been amazing! He has gained weight, he is eating and keeping his food down, he is more active, has more energy, and is back to his playful self ! I am so thankful I took a chance, what a difference this product has made. I would highly recommend!
