Mine went off at 3.30 and 4.25 am this morning. ( volvo not the S )

None of the security lights had been triggered so it was strange.

Got in the car this morning and theres mouse droppings on the dash

Had the boot out and there is the cutest little field mouse you have ever seen scared out of his wits.

The car is sat on my drive now , with the doors and boot open , and me hoping he will make his escape , otherwise its a mouse trap in there tonight
