What comes first? The father’s wife’s cat or the daughter?
This question comes across as a little odd, and the answer will depend on circumstances (“comes first” concerning what matter?) and on a bit of common sense.
Honoring one’s parents is a Torah obligation, but feeding his cat, and of course his wife’s cat, is not a direct obligation, and only a matter of following his instructions.
The question then will be whether these instructions conflict with some other obligation or prerogative, and this will depend on circumstances.
Of course, in general a person’s daughter will come before somebody’s cat.
