Sounds like you have some great ideas. I'm sure you know, but Big lots and Dollar Stores are great places to get toys and leashes. What would really be neat is if the kids could go spend an afternoon with the animals, but with liabilty and all that prob isn't possible. I have s recipe for "Magic Liver Cookies" that aren't too hard to make and dogs go nuts for if you are interested.

Really sounds like a good project. Good luck!
