I remember seeing someone mention once about how details concerning their BP collection was actually included in theirs and their spouse's wills.
If something serious did happen to you, what would become of your collection? Where would your animals go, or who would look after them?
They are questions that someone of your age might never think to consider. Heck, many people of all ages probably wouldn't think of it either, I know I certainly didn't until I read that post.
