I just wanted to add a viewpoint to this. While I can't speak as a parent, I can speak as a child who always had family pets, and if my parents had taken us on a family vacation and I knew my dog or cat was very sick, I'd be very upset about it. ....Just saying if that wasn't an option, the people who would cancel a family vacation to be sure their pet is ok, are not always "choosing" pets over family. I would assume in a lot of cases the children are just as concerned as the parents (again, depending on their age).
