Save my best friend Orange Kitty

Orange Kitty has been my cat and best friend for 16 years ever since I got him from the shelter. Over the past 3 days he has grown a large tumor on his rear left paw that needs to be amputated immediately. All of my money has gone to veterinary expenses just to get to this point and I'm praying that you can help me save him before the cancer has a chance to spread. The money will go towards his surgery, x-rays, and scans. Please, help this beloved family cat live and love a few more playful years with us.
