Metabolism cage with excrement and urine separation function and using method thereof

The invention belongs to the technical field of metabolism cages, and discloses a metabolism cage with an excrement and urine separation function and a using method thereof.The metabolism cage comprises a cage body, handrails and a top cover, a bottom cavity is formed in the bottom of the interior of the cage body, and a middle base and a limiting plate are fixedly connected to the interior of the bottom cavity. Deflection of the carrier plate is actively achieved by matching with the adjusting assembly during starting, urine and excrement are automatically cleaned and separated from the interior of the cage body under the condition that a filter plate is not additionally arranged, and the situation that the lower limbs of organisms are clamped when filter holes or gaps are formed is avoided; an electric push rod is matched to push an adjusting assembly to move and reset under the elasticity of a spring, a vibration effect is achieved between a limiting plate and a limiting rod, the separation effect of excre
