Maybe you were doing some Spring cleaning  in grandmother's attic and you uncovered an old fur coat. Now I'm betting most animal lovers wouldn't choose to wear it, but thrifting or selling the pelt isn't the best solution. Even if you donate the proceeds, do you really want to encourage someone else to wear it either?
Instead, ship the coat to the Humane Society's Coats For Cubs  program for a tax deductible donation. Upon receiving old furs, organization staffers cut up and distribute to comfort a variety of animals in wildlife rehabilitation efforts – I know I'd feel better having orphaned creatures snuggling or playing with this for their own feel better moment as well!
