The animal excrement collection system is composed of a disinfection pool, animal excrement collection DPTE transfer container, and scrubbing tools. The disinfection pool is oblong, has a slightly tilted bottom and a perimeter wall, and is close to and higher than the bottom transfer port. A drain valve is installed in the disinfection pool outfall. One end of a flexible diversion silicone tube is connected to the drain valve, and the other end touches the autoclave plastic bag inside the animal excrement collection DPTE transfer container docked to the bottom transfer port. The transfer container depth is 50 cm. There are stainless-steel lockable wheels under the bottom of the animal excrement collection DPTE transfer container.
