"checking the mail"

[James Callan]

>Is this expression commonly used in people parlance?  I have cats, myself.

My wife and I have friends in Portland, OR, who regularly referred to
their dog as "checking her pee-mail." Their phrase was definitely a
pun on e-mail, and dates to the '90s. I was under the impression that
they'd coined the phrase themselves, but I don't really know -- I'm a
cat person, too.
