I just ran across this information from United Animal Nations. It seems quite complete, and offers advice and a supply list for dogs, cats, reptiles & amphibians, and horses.

They also have brochures for spreading the word, $.30 each, although the first 5 are free. The brochures are pretty basic, and would fit in with your wanting to inform people without scaring them with too many details. I am thinking that a $20 order as a gift to my vet's office could get 65 people to start thinking about what could happen, and what they can do about it.
