I have no idea what Zagnuts were, but remember the patient in "ER" who was addicted to candy and they were his favorite.

Kitten with the litter issues--it may be that the litter is deeper than she wants. I imagine a kitten could feel unsafe in deep litter.

About masks: I don't think it's just about selfishness or not caring (though there is that, too). There's a deep aversion to mask wearing in US culture because at times in history, wearing one was prohibited. It was even against the law and was associated with criminal activity. This was especially enforced against non-white people. That's why during the 1918 pandemic there was such a huge public campaign and incentives, like reduced price theater tickets (yeah--should people have been encouraged to go to a theater in a pandemic???) for mask wearers. Think about all the cartoons where the bad guy is masked. Even raccoons are called "bandits."
