Each layer of the metabolic cage frame 2 is provided with a plurality of cage accommodation chambers, and each cage accommodation chamber is independent of each other. A metabolic cage cage body 1 can be placed in each cage accommodation chamber, and a rat can be raised in each metabolic cage cage body 1, so that each rat has an independent activity space. In this way, by arranging the metabolic cage frame 2 as a multi-layer structure, the space occupied by the rat metabolic cage is reduced, and multiple metabolic cage cage bodies 1 can be accommodated at the same time, more rats can be raised, and the space utilization rate of the rat metabolic cage can be improved. In some examples, the bottom of the metabolic cage frame 2 is also provided with 4 universal wheels, and the universal wheels have brakes, so that the free movement of the rat metabolic cage can be realized.

[0035] A funnel tray 3 is connected to the bottom of each metabolic cage body 1, and a urinary tube 4 is connected to the bottom of the funnel tray 3. The urinary tube 4 is wide at the top and narrow at the bottom. A corresponding urinary tube placement groove 5 is arranged below each cage accommodation chamber, and the upper opening diameter of the urinary tube 4 is larger than the transverse diameter of the urinary tube placement groove 5, so that the urinary tube 4 is stuck in the urinary tube placement groove 5. At least one filter screen for filtering feces is arranged on the bottom surface of the metabolic cage body 1. When rat urine appears in the metabolic cage body 1, the urine will flow into the funnel tray 3 from the bottom of the metabolic cage body 1, and then flow down along the inner wall of the funnel tray 3 into the urinary tube 4, so that the rat metabolic cage can collect rat urine.
