For non lethal mouse traps peanut butter supposedly does not work because it causes them to choke to death, if you are trying lethal mouse traps them choking to death would not be a problem. I do not know if they would choke on oil.
What would be best bait for fox traps? Someone above suggested Tofu instead of meat although I do not know why. Someone also suggested domesticating the fox after capturing it.
Tried to find laws on that to which someone replied fight cops
@shortstories I am talking lethal mouse traps. I do not factor in the mouse choking because the metal bar will kill him.
For foxes, I have no idea.
