Abstract: A base 12 supports small disposable containers 18 in an array. Each container holds a portion of litter 20. Containers are preferably transparent or translucent. In preferred embodiments a hinged grille 14 assists in the locating of containers within the base and serves to conceal the upper rims of the containers. A containment rim 16 is optionally provided for better keeping litter within the box. Container may be reused, or sealed with a snap-on lid 26 and disposed of without cleaning. Veterinary urine samples can be collected at home without stress to the cats. Amount of urine can also be determined even when litter has absorbed it completely by weighing the individual used container before and after soiling.
