As grandparents, my wife and I do frequent toddler babysitting.

The kitchen cabinets, drawers, and other compartments are very
tempting for our grand-daughter to investigate. We are looking for a
way to keep this closed and inaccessible to a young child, while
still allowing adults to easily open and close the doors and drawers.

Unlike 30 years ago when our own children were toddlers, we now have
very high quality custom cabinetry and drawers, and do NOT want to
drill or attach any fasteners which deface or damage the cabinets /
doors. The fasteners were used 30 years ago required drilling holes
into both the doors and the cabinets in order to attach the plastic
latches. This is NOT an option for our current cabinets.

Does anybody know of any device or fastener or method which provides a
secure and reliable latch to children, easy access to adults, and easy
removal without leaving any permanent damage to the custom cabinetry?

Thanks in advance for your assistance and suggestions.

When my brother became a father, his climbing gear moved into this role. He'd
run his web loops through the handles and fasten them with carabiners.
