I don't think it's silly at all! Other than long weekends for Thanksgiving, Christmas, and New Year's, I haven't been on vacation since I got Murray (male veiltail) and it does concern me. He lives at my office, so I can have my assistant feed him for me in my absence, and turn his light on and off, but for my longer vacation planned this summer, I think I will take him home and have my in-home pet sitter who watches my dogs and cats care for him there.
