Granulized litter compositions comprising a natural organic litter substrate for absorbing urine or other liquid. In order to improve the wicking ability of such “green” litter granules, which are initially slow to absorb liquid, the litter composition further includes a wicking agent to more quickly wick urine or other liquid into the natural organic litter substrate, where it is absorbed. In one embodiment, the wicking agent is provided as granules separate from the natural organic litter granules. In another embodiment, the wicking agent comprises a coating applied over at least some of the natural organic litter granules. The presence of the wicking agent advantageously improves the ability of urine or other liquid to be quickly absorbed so as to minimize and/or prevent any pooling that would otherwise occur.
