An animal litter composition comprised of a liquid absorbent aggregate impregnated with an agent to indicate the presence of sugar in the urine of felines and other related species includes 88.1 percent +/-5.0 percent by weight of an expanded aggregate, 00.9 percent +/-0.7 percent by weight of an odor control/antistatic agent, 07.0 percent +/-4.0 percent by weight of a clumping agent, 03.0 percent +/-2.5 percent by weight of a surfactant; and 01.0 percent +/-0.90 percent by weight of a glucosuria indicator. A method of detecting glucosuria in a feline includes providing the animal litter in a litter box or in an enclosure in which the feline is restrained until the feline urinates on the litter and then visually observing the litter for a color change.
