It is worth it, and in your heart you know it is, but these hard times are debilitating to the morale. You are already working intensely hard to save and assist many, many cats so a set-back like this can really feel exhausting. And now Scooter and Beavis are knocking the stuffing out of your bank balance, good job you love them so much! Very best wishes that all will turn out well with this new family.
