I knowingly used both terms. I think that I remember reading somewhere that vegetarian capsules (just the capsules - not what is in them) are are not good for cats. I am assuming if that is true, which I am trying to find out, then neither would be the vegetarian Taurine caplets that I just bought because they have something vegetarian in them. In other words I am trying to find out what makes empty vegetarian capsules unsafe - if in fact, this is true.
