So with this product with vitamin C, Echinacea and the Andrographis you suggest to take the one pill, and take out 1/8 of a teaspoon daily for one cat correct?

I didn't try the 1/8 of a teaspoon yet but I was just curious if there is a possibility that if the dose is too strong for the cat, can he vomit? Yesterday morning I gave him this product in his food and then few minutes later, he puked it up. Once in a blue moon, if he eats too quickly, and too fast, he will vomit. But he did not eat that much.
