Also wanted to let you know that the information at the Feline Rescue Network looks to be a separte organization that has combined with the NetPets Military Foster Program. (As in for information purposes...to get the word out that fosters are needed and available.)

They also offer an excellent contract that can be amended for those that are fostering animals other than cats.
Foster Contract

Just found a foster sign-up area for Operation Noble Foster This may be much more helpful to those who would like to foster cats.
