How to stop groups of cats caterwauling?

I say that's just not good enough ol chap , what seems the problem to me is that you have the afore mentioned bird bath podium stage in the wrong situation. You will have to call the local builder to erect a very nice and comfortable amphitheatre with adequate seating arrangements for the onlookers to admire and appluad the fine muscle feline as he parades and displays his mannerisms for the ladies. The builder can make the structure soundproof and d fine cloths about the place to make them feel at ease with their new surroundings. The construction can easily be built from a fine summer house or pavillion , and surely you would be able to get a good nights sleep if all the marauders and applauders are out of the aural reach of yourself. I would also ask the builder if he could place in form a suitable convector for when the nights are a bit chilly, especially when Samson is only dressed in fetching beachwear.. hope this can be thoroughly resolved for your slumber ...
