Cage for breeding an experimental amimal which is convenient for check the condition of the animal's health}

The present invention relates to a cage for experimental animal breeding, and more particularly, to efficiently separate the stool and urine excreted by the experimental animal while breeding the experimental animal, and to check in real time the amount of urine excreted by the experimental animal. It relates to a cage for laboratory animal breeding.

In general, a large number of laboratory animals are required in an enterprise or a university research institute that develops a new drug for an animal experiment to confirm the efficacy or side effects of a new drug that is developed in a company or a university research institute. Therefore, a large number of experimental animals are raised, and a cage for experimental animal breeding that can observe the experimental animals well while preventing external infection during the experiment is required.

In particular, when a new drug is administered to a test animal, it is necessary to check the health change of the test animal in real time to confirm the efficacy or side effects of the new drug. In general, the simplest way to check the health of a test animal in real time is to check the amount of urine excreted by the test animal and its components. For example, when an experimental animal has diabetes, the amount of urine excreted increases. On the contrary, when an experimental animal having diabetes is administered a new drug effective for diabetes, the amount of urine excreted by the experimental animal is checked. Changes in health status can be seen. In general, mice with strong fertility are used as experimental animals.
