Abstract
Abstract Smooth plastic or rubber granular material is used as an aid in taking a urine sample from a cat or a member of the cat family. The urine sample is necessary in order to carry out a complete physical examination in veterinary medicine and is of special importance in diagnosing disorders of the urinary tract. Novel apparatus is also provided for use with the granular material to aid in obtaining the urine sample without the need for manual expression of the bladder, cystocentesis or confinement of the cat within a special rack in the veterinarian's quarters or in an animal hospital.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
94 words
A urine collection system for cats and members of the cat family comprising a granular, non-absorbent, non-porous, hydrophobic litter which is capable of being spread in a pan, said litter having substantially cylindrical particles with a diameter between about 1 millimeter up to about 5 millimeters and a height between about 1 millimeter up to about 5 millimeters and being substantially smooth whereby the cat can urinate in the pan to permit easy removal of a urine sample at a minimum loss without the need to manually express the urine or catheterize the cat.
Claim 2
Dependent Claim
94 words
