Kind of Off Topic, but related
Kind of off topic, but I work at University of Buffalo and my office is in the same building as one of the larger dorms. Every spring when the dorms close for the summer, there are tons of items left behind by the students that can make wonderful dog beds. I've picked up memory foam, mattress pads, blankets, comforters, foam mattresses, pillows, towels, bath mats (great for crates), etc. I've even picked up some cheesy furniture I use in the cat foster room. Our university has large dumpsters they put out for just this purpose, but if you call student services, they might allow you to put out donation cans or allow you to dumpster dive. (It's not as bad as it sounds - these are household items, not garbage). The students don't want to transport them, so this is perfectly good stuff that is left behind.
I make the rounds, take things that I think would be useful, take them to a large laundry mat and wash it all in one of the large item washing machines and then I have dog beds and cat bed galore - at very little cost.
I have so many foster dogs and cats, that I sometimes have to throw items away for sanitation purposes. Plus if I have a foster dog with "bladder problems", once they are trained, I get rid of anything that might still have urine smells on it.
Just a thought.
