Well since cats are carnivores, is it cruel to have a cat chase a laser pen mousey when they can never actually catch the mouse?

It's been a while since I was a geology major but I learned that by the time of the K/T boundary, a lot of non -Avian dinosaurs were already extinct so it isn't like the impact killed the dinosaurs as much as it was the final blow.

Is that still accurate?

I wrote that Australia isn't as far south as Europe and North America, not America (meaning, the US).

But Melbourne is at 39 degrees south. Plus 42 north is Chicago and Boston. Even rural areas that latitude see very few auroras (aurorae?)

But it is pretty rare, no? I mean Australia isn't as far south as Europe and North America are north. New York state is further north in latitude than Melbourne is south in latitude and the Aurora Borealis is pretty rare even up near the Canadian border.
