One time I saw an account on some website somewhere of someone - I think, though I'm not sure, that she was an academic of some sort, though I'm not sure whether a scientist or not - who had selectively bred cats for intelligence over several generations, and her observations of the cats.
The cats lived in her house and there were quite a large number of them, maybe a dozen or so.
She reported the later generations of cats doing some remarkable things, most of which I've forgotten the details of - some of them rather disturbing, like an incident when several cats, working together, somehow lured a flock of blue jays into a room and then shut the window, trapping the birds, and killed them all. Or something like that - I'm not sure.
It was quite a long and detailed account, would possibly run to several pages of type if printed out.
Well, I now can't find the website. Tried searching for "cats bred for intelligence", "cats bred for intelligence experiment" and "cats selectively bred for intelligence" with no luck. (I originally found it via a link from another website - I thought it was a link from a Wikipedia page, but checking the "Animal intelligence" and "Cat intelligence" pages didn't turn anything up either). Does anyone recognise this account and know where it's from?
