I'm in the process of having one made. It was brought to my attention by my parents who saw a segment on TV re. pet wills.

I live on my own with my 5 furbabies, and even though my family has a key to my place in case I'm not home and something happens, this pet will is a really great idea.

It's set up by an pet and animal care organisation here in Denmark called "Dyrefondet" (the animal foundation).

What you do is write a will saying Dyrefundet will be given all rights to your pet(s) in case something happens or in case of your death.
All details on each pet is in the will (Their personality, health history and things like that) and you then state what you want to happen in case of your death or an accident. Dyrefondet will then go collect the pets and care for them according to your wishes stated in the will.

They've also provided posters and stickers I can put up on the doors here in case police, fire department or ambulance people need emergency access to my place so they can see there are live animals inside.

Just thought I'd share this very good idea
