Our Littermaid came without an AC adapter. I happen to have an
universal adapter lying around, so that's not much of a problem. All I
need to know is what voltage it needs and the polarity (that is, if
the center is plus or minus). The mA number would also be interesting,
but isn't cruicial.

This is usually written pretty clearly on the adapter itself, so if
anyone could just briefly look at theirs and either post it here or
email me at usenet@lar5.com I would really appreciate it. And so would
my smell sensitive room mates...
