Oh Vampire Biscuit, I’m sorry 😥 I’d be worried for Socrates as well. Might it be possible to introduce a new playmate to Socrates before you lose Nibs? That way they both get the benefit of a new member of the family and Socrates won’t be resentful of a new rat in the mix…..
I’m so sorry to hear Nibs’s tumor is coming back. You’ll just have to give Soc extra attention once he is alone. Maybe start now, so it won’t seem weird later. I hope he is okay, and that you are too.
