Posey the opossum is an animal ambassador who’s looking forward to meeting you at Castello di Amorosa for this year’s Wild Night at the Castle fundraising gala, but she won’t be the only one. Owls, hawks and other native Napa creatures join them for this event that benefits the Wildlife Rescue Center of Napa County, which helps care for orphaned or sick wild animals. Within the literal castle walls of the Medieval-looking estate, live music and savory dishes will delight as one-of-a-kind items go up for auction. There’s even a chance to win an “instant wine cellar” stacked with dozens of Napa Valley wines. Things get wild Saturday, April 4, at Castello di Amorosa, 4045 N. St. Helena Hwy., Calistoga. 7pm. $150. 707.967.6272.
