When we had our old (ancient) central heating boiler in the kitchen a mouse once made its home beneath it, behind the pump. We had a ginger cat, called Murphy, at the time. My husband, on discovering evidence of said mouse, picked the cat up and placed him next to the boiler, saying, "Go get him, boy", or words to that effect. The cat gave him a look that said, quite plainly, " Fer gawd's sake don't be so bloody stupid. What do you think I am, a contortionist?"
I solved the problem. I got a wooden spoon and banged it on the side of the boiler, for 5 minutes, with the back door open. The mouse, obviously with its ears ringing, shot out of the tiny gap under the front hatch and disappeared into the garden.
