Here in Wilmington, NC a fellow animal advocate is the site owner. No animal posts are allowed, but animal care items are welcome. Back when I was setting up the 'clubhouse' for Miss Annie the wonder dog in my garage, I got a twin mattress, small rug, TV and a radio tuner/CD player with nice speakers from my Freecycle friends. It's a shame that Annie wanted so badly to be a house dog, as her 'clubhouse' was just a super hangout.
There are similar areas at Craigslist, but I still prefer Freecycle. I use it at least monthly to declutter and rehome unwanted household and pet items. I request items less often. Give it a try when you need something that could be 'pre-owned!' Think of all the helpful things a foster parent could request: towels, pillows, dog bowls, leashes, collars....the list goes on and on!
