Molly, I'm afraid what will happen if the tumor is cancer and it is also HD. The rescue seems really caring, so I'm hoping they work with it. (Praying that it is not cancer or HD, though.) If he has the surgery done, I won't be able to foster him, I have stairs all over the house, everything is up one stair, three and four and then 13. I've also got pesty Killi and Shi. Pray that we won't come to this.
