There are many ways to catch a large number of mountain rats, such as using cages or using clips. The most exciting part is finding holes. Generally, its hole has several entrances and exits. You smoke it first and see where the smoke comes out. Leave only one smoking port and one exit, and seal the other holes. Seal the hole with a big bag at the exit, then increase the intensity of the smoke and add some chili pepper if there is any. The mountain rat can't stand it anymore and will run out of the only hole and go directly into the bag (remember, there must be someone guarding this place). If you are lucky, you may get a litter of more than a dozen.
Mountain rats are different from the rats hiding in people's homes. Although they both belong to the rat species and belong to the "snake and rat nest" animals, mountain rats are fatter and larger than rats. In order to survive, mountain rats must move around every day in search of food to satisfy their hunger. And because they are worried about being eaten by snakes, eagles and other natural enemies, mountain rats are always cautious and frightened. At the slightest sign of disturbance, they will immediately lose their souls. Scatter around and escape back to the cave.
