That's so nice of you!
A few ideas:
You might contact Baypath Humane in Hopkinton. They have an annual auction to raise money for the shelter and could maybe use those as items to auction off.
You might also contact Community Servings. They're a wonderful organization in JP that would know how to connect with an abused women's charity, or if they have clients in need themselves. They serve home cooked meals to critical ill people, but they're very hooked in to the nonprofit community and could certainly point you in the right direction.
