I think you need to make up an adoption application. One that states clearly all things that are important: No declaw, indoor only, etc. what ever you think is necessary. Everyone must read and sign. Tell this woman that you are sorry this was not mentioned at the first meeting, but how you ASSUMED that she knew how inhumane declawing is, you know, because she is in the rescue business......anyway, you cannot allow any cat that is under your care be declawed. PERIOD!
