Adams has not returned. I hope that he is safe.
So I returned to the Humane Society today and adopted "Tuffy", an eight year female, to be company for Adelaide.
I have renamed her "Abigail" in honour of President John Adams' wife.
The two cats are sussing each other out, but apart from a bit of hissing from Adelaide, they seem to be intrigued with each other.
Adelaide seems to have needed a bit of extra TLC this afternoon. She's been a bit stand-offish with me.
(But all the literature and lore suggests that two cats do better than one. So I think that Addie will adjust with grace).
I'll keep you posted!
