Help save my best friend Robin

Story

Hello, my name is Amy and this is Robin. Robin is only 7 and has been diagnosed with a mast cell tumour. Rarely seen in cats, dogs actually. He's had one operation where they removed a lump although it's very difficult to remove all the cells around it so he's having revision surgery also. To anyone who knows me, you'll know how beyond devastating this is. I see Robin as my equal and best friend. Having to make life and death decisions about someone elses health has been extremely stressful and seeing him in pain and destress probably even more so. He's been through a lot already but I'm going to do everything I can for him, I wish I could donate an organ or something! Any help matters and is extremely appreciated. All funds will go to Robins surgery and recovery (aka Dreamies!) Thank you
