The PayPal donation button is set at $10.00 intervals, if you wish to donate more then the stated amount, simply select multiple quantities for the desired amount. Please remember, we are a non profit 501c(3) organization ran by volunteers only. There are lots of expenses associated with taking quality care of the animals in our program. Anything you give is more then we have, so we sincerely appreciate the difference you are making with your donation. We will gladly provide you with a receipt of your donation for your taxes. THANKS for helping us help those in need.
