What an unwelcome news, I'm so sorry!
I wanted to react yesterday, got distracted and forgot about it, only for you to haunt my dreams!
They were nice dreams by the way, despite me feeling guilty for forgetting to react in my dream. You were just as nice in my dream as your granddaughter seems to think you are.
I had to look up the thread today to see if I dreamt your whole post too, disappointed to see the part on the cancerous cells was not just my imagination.

I admire your stoic approach on 'doing without', and I'm very happy this is not something which is something like unacceptable for you, which would have made things much harder. On the other hand, an operation like that can't be easy on your body, especially with your other health issues.
I have my fingers crossed they can help you with minimal issues for you!
My household has its own little drama's. Just last week I bough a giant guinea pig pen for in the living room to house an elderly guinea pig with foot problems so she wouldn't have to spend the winter outdoors.
I moved her in with another guinea pig to keep her company.
This morning I found her in one of the hiding places. At least her last days were comfortable.
I've put another guinea pig in with the remaining one, as I don't dare put it back outside now it's gotten used to warmer surroundings, so I now have two indoor guinea pigs who didn't need it!

Still, I like watching them, so it's not really a bad thing.
