This is neither necessary nor possible. Swiss hunting is regulated and monitored by the federal government and the respective cantons. There are quotas that are adjusted depending on the animal population in the respective cantons and distributed among the hunters. So the number of marmots that can be hunted each year is fixed and adjusted to the population. The population of these wild animals is controlled by hunting in order to prevent and contain overpopulation and thus diseases.
We have a large network of Swiss hunters and buy the valuable marmot fat, chamois fat and badger fat directly and exclusively from them. This is a lot of work, as each individual hunter is dealing with smaller quantities of marmot oil, chamois fat or badger fat.
