Rats (1.21)

Rats are very cowardly, so taming them will be as difficult as cats. You can tame them with potatoes. These mobs will put a certain type of item from different chests into one chest. But be careful, these rodents can destroy potato crops, but tamed rats will turn them into experience; the more the crop grows, the more experience. Along with rats, you can add underground burrows, small caves that will consist of rooty dirt, they can be found under the Forest biome, where rats will spawn. They can also be found in Lush Caves
