Distribution

Although not a part of staple human diet in Cambodia, a growing market has developed there with most exports going to Vietnam.[2] Rat-catching season reaches its height after the rice harvest in June and July when rats have little to eat. That lack of food coincides with seasonal rains that force the rodents onto higher ground, where traps are set up to catch them.
