Id say that sometimes you have to do some things to get to do the other. if you put some poison down on a farm he will know that you are really trying to control his pests and will be more likely to let you rabbit, shoot etc. my dad is a farmer and if he heard that the people didnt actually want to get rid of the pests but keep them there for fun then they would lose all permission very fast. and its not all about fun, there are way too many rats everywhere so you dont need to preserve them for god sakes
