In my series of books the Mitten Kitten Heroes, anytime the Kittens come across buried treasure or something along those lines in their adventures, they donate the money to local animal shelters!
We have three wonderful rescue kitties ourselves, and although they are not Joss, Gust and Edwina, the Mitten Kitten Heroes, they still are daily inspiration for the wonderful work that pet shelter and rescue organizations do every day.
Below is a list just getting started (will be adding to it regularly) of great shelters for you to contact, donate to, volunteer with, and of course go and give some creatures their forever home.
