since i just got notification of a favorite for this thread, I figure i'd give an update and report that Bailey (one of the 3 stray kittens we caught and adopted out) just passed away due to sudden onset kidney failure. Both bets (primary and animal hospital) think it was pre-existing condition that just decided now was the time for it to take effect. Worst part is it's my mom who's suffering right now, as she adopted Bailey and Grayson. Bailey was 7 months old.
