The Toronto Humane Society struggles as global warming results in more hours of daylight.
From which we can extract the following argument:
1) The humane society claims that global warming is behind the explosion of winter-born cats.
2) As cats mate only when there are over 8 hours of sunlight in a day, they can't breed in winter (September to January, to be precise).
3) The explosion of winter-born cats can't be caused by Global warming.
However, even if valid what the argument actually proves is that the explosion of winter-born cats the Toronto Humane Society claims to be seeing isn't happening in the first place (cats can't breed during the short, dark winter days), and therefore can't be caused by Global warming. Hence the Toronto Humane Society are lying commies bent on wealth redistribution.
In fact, the argument fails outright:
Long haired breeds tend to be more seasonal than short-haired breeds, with 90% of long-haired cats experiencing a period of anestrus compared to only 39% of short-haired cats. In an extensive survey of 168 queens, approximately 50% of cats cycled year-round while the remainder experienced a period of anestrus from September to the end of January.
Some cats obviously can breed through the winter. It's presumably these lucky cats that are doing the EXTRA breeding.
And actually I didn't even have to google this, just scroll a few lines further down through the link Kate provided. Clearly, she expects her regular readers to get tired after the first paragraph. Its hard work moving your lips when your sucking your thumb, I guess.
