To say that a being who is sentient has no interest in continuing to live is like saying that a being with eyes has no interest in continuing to see. Death—however “humane”—is a harm for humans and nonhumans alike.
There is no moral distinction between fur and other materials made from animals, such as leather, which also is the result of the suffering and death of sentient beings.
