Some fur comes from animals caught in horrific traps. Leghold, Conibear traps and snares are non-selective devices, which means that there are many 'non intended' animals who get caught in these barbaric contraptions. These traps are banned in 88 countries, but leghold traps are still widely used in the United States and Canada. Legholds are spring-loaded steel jaws that clamp shut on an animal's foot once it's sprung. It causes injuries and loss of circulation.
Snares are wire strangulation noose that tightens around an animal's neck or body.
It is usually used on fences to hang animals or under water to drown animals. This is a picture of a poor fox caught in a trap that is used for catching animals. The animals are stuck in the trap for hours or even days before the trapper comes to pick them up. Some animals try to chew and bite their own limbs off just to get out of the trap. That sure speaks volumes about the pain they must be in.
