ABSTRACT:
A cat litter which comprises a plurality of lightweight, resilient paper strips treated with a pH-indicator and/or an occult blood indicator and folded transversely into generally zig-zag shapes, enables early detection of feline urological syndrome. When wetted with alkaline urine secreted by the cat, the paper strips treated with pH indicator exhibit a noticeable color change. When wetted with cat urine containing occult or gross blood, the paper strips treated with occult blood indicator exhibit a noticeable color change. A mixture of pH indicator treated strips and occult blood indicator strips in the cat litter enables the detection of both alkaline pH and occult blood in the same urine sample. The color changes are easily visible to the observer without requiring unsanitary contact with the cat litter.
