MM,

It all depends on how oyu package the Catnip. If it's in something like a ziploc bag, then the recipient is probably going to get an envelope full of loose catnip. If you used the puffy envelopes it would probably be fine, as that mail gets run on different machines. (though marking it as catnip would probably get around any scrutiny you might get for mailing small envelopes of dried leaves...LOL)

Buckner,

If you want it to get there before Christmas, give the package a MINIMUM of a week. You should be well within the three-four day zone, but I'd check with the clerk when you bring the box to the PO.

QS,

All I have to say about pens, mini calendars, magnets, etc. is I HATE INSURANCE COMPANIES! They seems to be the worst offenders, other than our own Bulk Mail acceptance people. Chocolate isn't the worst thing I've had to clean out of a machine by a longshot.
