I just learned of this program and hope folks who have an old fur they'd rather not have now know where they can donate it without worry that someone else will be promoting cruelty by wearing the fur they donated.
Coats for Cubs is a program of the Humane Society of the United States. Fur items donated are used by rehabilitators to comfort orphaned wildlife. Those who own or inherited furs can't turn back the clock and prevent the item from being made in the first place, but they certainly can do good with them now.
Send Grammy's old stole to HSUS. She nurtured you, now the stole you won't wear can carry on her nurturing and love with a wee one who needs comfort and warmth to grow.
