"A Sentimental Journey" Fundraiser for the Doris Day Animal Foundation - April 3-5, 2014

"As you may know, I’ve never been very keen on celebrating birthdays," Doris Day wrote in a note announcing "A Sentimental Journey," her three-day fundraiser for the Doris Day Animal Foundation (DDAF). "I’ve always thought age is just a number and has little to do with how we feel. But, it’s true. I’ll be 90…I can hardly believe it! So I wanted to do something special for my fans and friends who have been so devoted all these years, something celebratory to bring them together and that would warm my heart, as well."

Not content to simply celebrate her own personal milestone, Day asked her team to expand her traditional birthday gathering at the Cypress Inn into a three-night extravaganza benefiting the DDAF, which she founded to help animals and the people who love them. Named for her first hit song, "A Sentimental Journey" will include a pet fashion show featuring Day’s beloved "four-leggers," live entertainment, surprise guests, a silent auction and a raffle. Space is limited, with room selection on a first-come, first-served basis. To learn more, fans can call the Cypress Inn at 800-443-7443, or visit www.dorisday.com/90to90.
