Helps with my cat’s diarrhea
Read More
I’ve tried other products and some of Vitality Science’s other products for diarrhea but did not help for my cat. I saw that this product helps with diarrhea so I decided to give this a shot and it worked. I guess my cat needed a little extra calcium in his diet. I wont stop using it because if I do than poor Storm needs to get butt baths which he doesn’t like.

Hello Stephen, many good wishes. I doubled the dose of the calcium white powder (Lithothamnium) and the soothing solution. I left out the anti inflammatory to see what would happen. I initially gave her 6 calcium pills per day and 6 soothing solution drops per day. I spread the doses out to morning, noon, and night. Over the last few days I have noticed gradual improvement. Today, she has a completely normal stool!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I am almost afraid to exhale. This could change the quality of her life and mine like you would not believe as the last two years have been rather stressful with her diarrhea etc etc etc. Now we can sleep through the night for one thing.
Lithothamnium is the shiznit!

Hi Steve, Good news – Lithothamnium is the shiznit! Clarence is no longer pooping on himself and is able to make it to the litter box without pooping on the kitchen floor either. He seems real pleased with himself too. He’s had a good bath & looks fluffy again. Now he wants to mingle with the other animals a little bit instead of snoozing disconsolately in a fruit bowl. Thanks for the good advice.


Lithothamnium is more than just calcium for cats, it is composed of a wide variety of body essential nutrients including Calcium, Magnesium, Boron and Zinc. It is also very absorbent, and can dry liquid stools fast. This product should not be given to felines with firm stools.

Lithothamnium derives its calcium and minerals from a natural calcified red seaweed product harvested from the sea bed off the South West Coast of Ireland. Here, amongst the cleanest and purest waters found in the world, grows smaller red seaweed Lithothamnium. This calcium is 100% natural.


  • Promotes healthy bones
  • Promotes strong joints
  • Relieves mild to chronic diarrhea
  • Provides calcium
