In view of the increase in the number of cases with nephropathy in aged animals of the cat family, the invention provides a marker for early diagnosis of feline nephropathy which can substitute for the conventional complicated methods of diagnosing nephropathy such as blood examination, kidney radiography using a contrast medium, and ultrasonic image analysis. It was found that cats with nephropathy show markedly lowered levels of excretion of a novel protein (named cauxin) with a molecular weig...

A method of reducing the concentration of metal contaminants, such as vanadium and nickel, in distillates of a fossil fuel feedstock is disclosed. The method comprises producing a selected distillate fraction and demetallizing this distillate by suitable means, thereby upgrading and making it suitable for use as feed to a catalytic cracker.

The disclosure relates to a cat exercise device in the form of a post structure that is applied between the ceiling and the floor of a room, comprising a body portion that is proportioned to extend a substantial portion of the height of the room and a leg projecting from either end of the body portion to engage the room ceiling and floor, respectively, one of the legs being resiliently telescopingly mounted to accommodate varying ceiling heights and provide a biasing action to secure the post st...

A pet door comprises a frame defining an aperture in which a flap is pivotally suspended so as to close the aperture when it hangs vertically.
