Half hour later I catch mouse and evict, still live. Two weeks later cat comes into lounge and mews loudly. Search and can't find anything. Relieved - all quiet. One week later, washing machine flood.
Engineer opens top of washing machine.
Mouse sitting happily washing itself. Fast disappears into washing machine. Engineer and I spend 20 minutes trying to shake out mouse. Evenually comes out and is evicted - live again. Inform cat this is unacceptable behaviour.
