Lithothamnium is more then just a calcium supplement 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 animals with firm stools.

Lithothamnium derives its calcium and minerals from a natural 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 the small red seaweed Lithothamnium.

The Seaweed eventually grows into a hard and brittle coral-like structure. Local tide patterns deposit the seaweed in large deep beds. The material is dredged from the ocean floor, washed thoroughly in fresh water and the highest quality fraction is separated to be taken to an ISO 9002 certified food facility. Here the material is carefully inspected, sterilized, and dried then milled to the required particle size.

Review of Lithothamnium 150g | Calcium for Cats

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.

Review of Lithothamnium 150g | Calcium for Cats

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.

Review of Lithothamnium 150g | Calcium for Cats

Teddy is doing extremely will with your products, I have added Lithothaminium into the mix with luxiolite at night. I noticed his recovery rate is faster and I see life back in his eyes, so much more calmer and content. I can’t believe that I thought that was just part of his breed and not being healthy. We went to the ocean for 4 days and brought teddy with us. I only heared him yell in pain once in all that time. I do know he still has a bad disk in his neck that flares up at times, but it has been improving with warm water therapy and message. I was walking him 3 times a day and he keeped going, he seemed tired which I expected but didn’t stop going. He even ate something on the beach like slimmy seafood, and never once vomited. My husband gave his new supplements credit for the non vomited teddy. Such a different expectation for us. I feel myself getting surprised with the new teddy every day, he is always doing something new or different then from before. He used to lick the rug floors for hours, that has totally disappeared. He still licks my husband arms and legs and head if he gets a chance for quite some time. I think teddy loves a big salt lick or there is something else in my husbands blood or skin that tedddy loves. Have a great day.
