I'm so sorry to hear about your loss of Star, Alyssa . Budgies can live from 12-14, but they can be very fragile and hide illness well. She may have been older when you got her from the pet store. She reminded me of an albino my mom had when I was younger named Angel. Angel also passed away suddenly one day without showing any prior sign of illness. I know you will miss Star very much. Perhaps she will meet up with Angel at the RB and other beloved keets I have known. They are special little birds.
