Obviously anybody who thinks that real cats don't have options has
never owned a cat.
"man cat" may not list them, but that's because you're asking a man
about cats,
not asking a cat, not that the cat is necessarily inclined to tell
you its options.
"cat -h" or "cat --help" doesn't work, because your cat isn't going
to help you.
"cat --help food" might work, but your idea of help and your cat's
idea may be different.
More seriously, though, "cat -u" is sometimes important,
because sometimes you really do need unbuffered output,
especially if the file or files are devices or other special files.
