What to do if a bamboo rat bites the wall? Practical solutions shared

What to do if a bamboo rat bites the wall during bamboo rat farming?
In bamboo rat farming, sometimes bamboo rats bite and gnaw the wall. So how do you solve this problem? How do you prevent bamboo rats from biting and gnawing the wall?
First of all, when a bamboo rat bites and gnaws the wall, it is the bamboo rat gnawing its teeth. So does a bamboo rat need to gnaw its teeth every day? Does eating hard bamboo count as gnawing teeth, and should you give it a stone or an iron bar to gnaw on? Because bamboo rats have two huge front teeth that keep growing every day, gnawing their teeth is something they must do daily.
Some people use king grass for bamboo rats to gnaw their teeth. The hardness of the outer skin of king grass is similar to that of bamboo, so it is very suitable for gnawing teeth, or you can directly use hard bamboo for bamboo rats to gnaw their teeth. If you do not provide anything hard, then your wall will definitely be bitten into a hole or gnawed into a big hole. That may also let the bamboo rats escape, so the loss outweighs the gain. And if we are not at ease, to prevent bamboo rats from biting and gnawing the wall and escaping, we can coat the wall with a layer of smooth cement.
But note that if a bamboo rat wants to gnaw its teeth and has nothing to gnaw on, then the bamboo rat's teeth will not grow well. If the teeth do not grow well, then the bamboo rat cannot eat well either, and the final result will cause the bamboo rat to become thin, and in severe cases it will lead to the death of the bamboo rat.
In short, we must give bamboo rats something hard to gnaw their teeth on, and if the wall is also made smooth, then the problem of bamboo rats biting and gnawing the wall is solved. I believe that after taking such a measure, your bamboo rats will definitely grow up healthily.
