My good veterinarian helped Luna cross over today.
She had developed neurological symptoms and was having difficulty eating and drinking. She passed peacefully in my arms, with the sun shining down on her and me brushing her... her favorite thing.
Another friend said, "You couldn't have been luckier with a first goat."
It will take me a while to stop looking for her sweet little face, but I hope I never stop remembering how much she brightened my life.
