1. A pet litter, comprising a plurality of health monitoring particles, each of the health monitoring particles consisting essentially of:
a porous base material; and
a plurality of additives applied to the porous base material, the plurality of additives including a first additive that includes color particles conjugated for a target analyte and a second additive, the first additive and second additive co-present on porous base material particles, thereby causing a change in color of the pet litter when coming in contact with pet excreta, and wherein the change in color is indicative of the existence or non-existence of at least one medical condition in an associated pet,
wherein the first additive is positioned on an exterior surface of the porous base material and applied as a membrane that is configured to dissolve and facilitate release of the color particles for adsorption into pores of the porous base material, and wherein the second additive is contained within the pores of the porous base material.
