The worst thing is when the fricken mice eat through the wiring loom and ive seen it happen causing all sorts of problems.... Best one was me cousin opened his bonnet on the cossy & seen this big fck off RAT on the rocker cover lol. I missed it but must have been amusing at first as he just slammed the bonnet in shock thinking what to do after a few moments lol...

Do soming about it before it becomes a major problem for you

Best of luck
