Hat had a late dinner and was dozing in the basket. Spencer was having her fur brushed again, and she must have said something to Hat, because Hat suddenly jumped up with a look of terror on his face and ran out of the house. Silly boy. No sign of BH2 and old tom.

I think Mera left paint pawprints all over the corridor. He must have jumped out yesterday when I left for work, and when the paint on the wall was still wet. The only way to prove is to see if he has paint on his paws.
