Since nobody at the ulster county S.P.C.A can return a phone call...maybe I will get an answer this way.... does anybody know if they can use a futon mattress?

Valerie, thank you for the offer but futon mattresses are too large for our dog rooms. We do not have a use for them. We are always happy to accept towels, blankets, sheets, and clean linens. There is a donation bin outside of the building. Thanks for thinking of our animals.

Do I just drop it off?...if so where?

Yes they can.
