Mouse and dressing gown

This morning the three of us were playing a computer game (we do that quite a lot) when R heard a squeaking noise from his bedroom.  On investigation, Saphy was staring intently at the radiator, and we knew immediately that she had brought something in.  Sure enough – it was a mouse.  She had caught it and carried it back to the den in her jaws, but as usual she didn’t have a clue what to do with it.  She didn’t even mean the poor little creature any harm or want to eat it – to her it is just a little toy that goes squeak.

Anyway, R and I love all God’s little creatures (well apart from bluebottles and ticks) so as usual we managed to catch it in the whisky tin we keep for the purpose, but this took 20 minutes and involved moving the wardrobe and the dressing table.  We let it go in the garden and it shot off – it really was a beautiful little thing.

And then in the evening, I left my dressing gown lying on the bed while I had a shower.

It is a silk dressing gown with a belt, and when I left it, the belt was securely attached to it.

However, when I came back 10 minutes later, the belt was gone.  After a thorough search I found it ten minutes later halfway down the stairs.

How could this conceivably have happened?  Could this creature possibly have been responsible?

Surely not.
