At least one of the floor and the wall is made of a material including resin, and has an excretion hole to allow the excrement in the animal residential area to be discharged to the excrement collection area, and the excretion hole has a size that prevents four feet of the animal from entering the excretion hole. The excretion sheet faces the excretion hole.

Rearing cage unit and rearing apparatus

There is provided a liquid supply apparatus eliminating the need for a power supply, having relatively light weight and small footprint, and ensuring a stable liquid supply. The liquid supply apparatus includes a first support member, a second support member, a balloon having one end supported by the first support member and the other end supported by the second support member, and a casing having a constant longitudinal length. The balloon is disposed in the casing and is configured so as to be able to hold a liquid therein and discharge the liquid therefrom. When the balloon holds the liquid, the one end and the other end of the balloon are positioned in the case.
