Since moving to my wonderful "country home", I've noticed that Bogie (aka Monster) has spent more time grooming, and been more... well... determined about it. We went to the vet, who couldn't find anything wrong and suggested Feeliway to alleviate any stress. That seemed to work but then, winter hit again and the aggressive grooming started again - he's now got patches on his arms and legs that are nearly bare.
Was all this country living getting to him? Did he pine for the noise of Brooklyn (or the horribly cold cottage we lived in between Brooklyn and Country Life)?
Then I had a brainwave: I have an oil heater. My skin was dryer than usual, perhaps his was, too. So now we have a humidifier in the bedroom and he seems to be much happier.
Best purchase I've ever made, and one I highly recommend to anyone who uses oil heat.
