Would a Korat be too sensitive for a constantly changing household schedule?

Korats are indeed sensitive cats, but it's not so much about schedule changes as it is about human interaction. They form strong bonds with their people and want to be involved in whatever's going on. A constantly changing schedule isn't inherently a problem for them-what matters is that when you're home, you're present and engaged with them.

The bigger risk with a Korat in a busy household is not the schedule itself, but if the cat ends up feeling ignored or left out of daily life. They can become anxious or withdrawn if they sense they're an afterthought. So if you can maintain quality playtime, lap time, and consistent affection when you're around, a Korat will likely adapt to the chaos just fine. If your lifestyle means the cat gets sporadic attention and long stretches of being alone, a more independent breed might be a better fit.
