They're here!

Two black and white, a grey and white one, and a tabby, either grey or brown. The idiot gave birth to them under the sofa in the basement, then took off and left them there! My mother found them when she was looking underneath for some reason and saw a leg. They were all huddled together to keep each other warm.

They're in seclusion in another room (with a closed door!) and nursing now.

Stupid, stupid cat!
