For cabinet doors that are a pair swinging to the left and right with handles in the middle, I use a mini-bunge cord (about 12-inches) to secure the handles together. (These are handy for other things such as securing items in the refrigerator, so I keep a supply on hand.)
For a cabinet door that is not one of a pair, I use a simple screen-door latch. Not elegant, but it is effective.
I have had no problem with drawers and have no suggestion there.
(My wife & I just finished our thanksgiving lunch of mushroom-tartlet appetizers, sweet-potato soup, baked oysters, and a medium-dry sherry. Not your usual thanksgiving fare, but we enjoyed it, just the two of us.)
