How do bamboo rats replenish water on a hot day?

In spring and winter, bamboo rats generally don't need to replenish water. If the mother mouse gives birth to a mouse, just don't mix it up when feeding rice and chaff. If the mother mouse has no milk, she can feed some glucose (injection), open it and shoot it into the mouth of the bamboo mouse with a syringe (pulling out the needle). In summer and autumn, the weather is hot, and the bamboo mouse needs a lot of water. Rice grains mixed with bran can be wet. You can feed sugarcane, raw sweet potatoes, corn stalks, carrots, sorghum stalks, pumpkins, etc. But don't feed too much at a time, too much won't do, it will lead to diarrhea in bamboo rats. Don't feed it every day, bamboo is indispensable.
