I had responded to Liv privately as the info I had for her was something I
posted on the list in the not too distant past, but since I've seen further
comments and questions since then, I thought I'd cut and paste this for
everyone to see:

If by magnetic snaps you mean the ones that have a little metal plate on
the door and a small magnet that mounts on the cabinet case, they probably
will make little difference.  What we use are child safety locks called
Tot-Loks.  They are also magnetically based locks, but they are *very*
strong and require a "key" to release them.  You will *not* be able to
release them without the key or an otherwise VERY strong magnet.  The
Tot-Loks have recently been purchased from the Rev-A-Shelf company by the
Safety 1st company.  Some folks have seen these locks in home improvement
stores or Wal-Mart stores.  Locally I find them at Babies 'R' Us stores.
They may also be in Toys 'R' Us.  The neat thing is that though the locks
are permanent installations, they can be disabled if you don't want to use
them by simply flipping a switch on the lock before you let the cabinet
door close.  To see a picture of the lock, try this website (also the
cheapest online source I had found when I looked a few months ago):

I notice that the Wal-Mart site lists at least three products in their
online store but only shows the extra key actually available for purchase.
Home Depot carries Safety 1st products, but last time I looked didn't have
these locks (though this is the first place I bought them several years
ago).

I looked up my receipt from June and found that I paid:
 
$12.99  for a package of four locks with no key
$11.99  for a package of two locks with one key
 
That'll show you how retentive I am... looked up the date of purchase on
the computer and knew where to go to immediately pull the receipt!  I
really MUST get a life...
