I can haz climate change?

Climate change has lengthened the moggie breeding season in Australia, from October through May (that's summer down under), leading to "record numbers" of cats being born. On the one hand, this means pet shelters will be overburdened with unwanted felines. On the other hand, this is a perfect time to enact your plan of swimming Scrooge McDuck style in a pool full of kitties.
