Help sweet baby Annabelle

this is Annabelle, she’s a 16 year old Himalayan cat that I’ve had for 12 years. She’s a rescue. Annabelle has been my rock and now it’s time for me to pay just a little back to her. She has mass that needs to be removed. We are looking to fundraise enough to cover her medical expenses. She’s not a likely candidate for surgery due to her age but we’re holding out hope for our little trooper. She is my everything and it pains me that I can’t help her by myself. Please help any bit you can.
