I was sitting working at my computer just now and noticed my cat Jessie looking very interestedly at the big bag of catfood next to my desk. She was... listening.
Then I noticed faint sounds coming from... inside the bag!!
The bag was clipped shut and I clipped it a LOT more shut!! And listened some more and the noise would stop, then start again.
Then, tried to decide how in the world a mouse got in the bag, and how I was going to get the bag outside without mouse escaping, and get the mouse out of the bag outside.
As I was steeling my nerve to do this, I thought I heard a faint... buzzing! Listening some more, I realised a large fly was trapped in the bag, not a mouse.
I cannot tell you how happy I was to open the bag and watch a fly buzz away.
