<p>A system which separates the pet excreta collection, storage and disposal functions is disclosed. Each individual component used to perform each of these functions can thus be optimized for its intended purpose. In simple terms, the present invention comprises the combination of a nonsorbent, nonclumping granular litter material (1), a sorbent means (3) for the collection of urine underlying the nonsorbent, nonclumping granular litter material (1) and a filter (2) for the removal of solid or fecal matter from the nonsorbent, nonclumping granular litter material (1). Such a system permits almost indefinite recycling of the nonsorbent, nonclumping litter material (1) without adverse effects.</p> |
