Yes, that is correct, this is cat littler the alerts you to the fact that there is an odor by turning color. Now pardon me if I just don't see the point, but one would think that the fact that there is an odor would be readily discernible by the odor itself. Maybe this product will be marketed to those who have lost their sense of smell, but that seems like a very small market. So apparently, Arm & Hammer has come to the conclusion that what America really needs is a cat littler that tells us it is smelly by turning colors. Until next time...happy smelling/seeing.
