Cat on windowsill looking pathetic so DH let her in, failing to notice the enormous mouse dangling form her jaws 
Mouse was released by the cat & somehow managed to squeeze itself under the range cooker by apparently dislocating its hips & wriggling on its belly.
DH has been swiping about underneath with a garden cane
as if that was ever going to work.
Cats were quite interested in the underneath of the cooker for about five minutes & are now doing other things.
The mouse is presumably round the back of a cupboard, chewing the shit out of things. Sigh.
