The following news snippet was pointed out to me recently:
More cat owners ‘have degrees’ than dog-lovers
I wonder if people with degrees tend to be more bookish and less sporty or active in general… there’s always been a link in people’s minds between writers, artists and cats. An artist or poet is not going to be happy at being interrupted in the middle of their great masterpiece by a canine wanting to go out! It would no longer be the Man from Porlock in that case, but the Dog from Porlock.
Any other ideas?
