Huh? Either you live in Canada or you don't. I have no idea what you mean by "the European equivalent thereto". You'd need a country that has 6.5 time zones and every type of ecosystem we have here. Even British Columbia has everything from semi-desert to temperate rainforests to areas where houses can get almost buried in snow during winter. And noticeable parts of the Arctic are literally melting and sloughing off into the Beaufort Sea.
Try telling an unspayed cat to ignore her natural rhythms. You have three choices, if you want to keep the cat: Extreme levels of tolerance for days of screaming and howling, a very good set of earplugs, or just get the cat spayed.
I suppose you could find a tomcat and let them do their thing and deal with the kittens that will come along 2 months later. But then you'd just have the same problem all over again after the kittens were weaned 5-6-weeks after birth.
Don't presume to tell me that I can just ignore the natural rhythms of the seasons I grew up with. Maybe some people can, and maybe some people have only ever lived where there's one season and they can't imagine what it's like to have changes. I don't actually spend a lot of time outdoors these days, yet the change of the seasons matter very much. It's doing its best to sleet outside right now (had snow overnight, and what's coming down now is a cold, sloppy mix that's not solid enough to be snow but would be if the temperature dropped a bit or the wind picked up). It's going to make for dangerous driving tonight and I suspect some kids will be kept off the streets for Halloween. But for me, it's a relief to finally get some calendar-appropriate weather. Snow at this time of year is normal.
I've honestly found it mind-croggling to see people on the forum post that they've never seen leaves change in the fall, or that they've never experienced snow.
That was in response to incompetent bureaucracy, inconsiderate kids, inconsiderate people, people who just wanted to be obstructionist because they had the authority to go on their own little power trip.
Not sure what it has to do with moving to California.
