A litter package has a body of litter within a container of waterproof material and is for use by a pet animal after the package has been opened to expose the litter substantially throughout the area of the container when disposed for use. The litter body consists of particles of absorbent material or materials that are chemically neutral when wet. Testing means are associated with the litter and of an indicator type changing color if wetted by urine containing a color-changing reactant indicating an unfavorable health condition. The testing means may be incorporated in litter material, carried on the inner surface of the container or on inserts in any case when the package is open, the testing means includes at least one unitary portion under each position the animal may occupy while urinating and of an area such as to become wetted at least in part by contact with urine-wetted particles in the normal use thereof thus to be subject to the reactant throughout a predetermined time. The indicating means may include different types of indicators, each changing color in response to different reactants, the colors being different for each reactant.
A litter package comprising a container of transparent waterproof material, a body of litter within the container for use by a pet animal after the package has been opened to expose the litter with the litter covering the bottom of the container when disposed for use, said body consisting of absorbent particles that are chemically neutral when wet, and testing means within the container and of an indicator type changing color if wetted by urine containing a particular color-changing reactant indicative of an unfavorable current health condition of the animal, said testing means so located within the container that when the container is disposed for use, test areas are provided where they will become wetted by urine in any position the animal will normally occupy while urinating during a predetermined time interval, each test area dimensioned to provide a colored signal, if said reactant is present in the animal's urine, that is readily distinguishable from the remainder of the litter body during the disposal thereof.
An absorbent material package adapted for use for receiving animal litter comprising at least one container for said absorbent material, said container adapted for enclosing within the same for storage, use, and disposal said absorbent material, said container adapted for opening and for receiving litter from said animal within said absorbent material, said container further adapted for closure and/or discharge of said litter within said absorbent material.
