I don't know why this has only just crossed my mind but anyway........

Let's say you have a website about Cats, a directory that lists cats.

It's broken down into MALE cats and FEMALE cats under female cats you have....

Cat A
Cat B
Cat C

and under male cats you have

Cat D
Cat E
Cat F

If Cat B decides she's such a pussy that she doesn't want to be on the directory anymore what is best practise ??

1) Delete Cat B's page and have a 404 error default to the index page OR
2) Delete Cat B's page and do a 301 redirect to the FEMALE cats page ?
