Perhaps back in the 50s it was perfectly reasonable, from a societal point of view, to say things like “I am the man of the house” and expect to be taken seriously. A husband could get away with having the last word in an argument, whether it was about what was for dinner or where they were going on holiday.
These days, however, we’ve thankfully moved on from the misogynistic expectation that a man’s opinion is more important than his wife’s. Often, if it’s a situation to do with the household, it’s the woman who gets the last word. Mainly because they’re the ones who will have to do all the related work. So, kitten it is, and he’ll grow to love them and their fluffiness.
