We never child-proofed for the human children, but rather because one cat kept getting into drawers, cabinets, etc. The magnetic locks solved the cabinet problem. One cat kept getting in there, letting the other cat in the cabinets, then closing the cabinet door - the other stupid cat couldn't figure out how to get back out.

We installed some sort of plastic hook thing on the drawers, but the cat figured out how to open the child-proof drawer hook. The drawer child-proof item must be meant for human children, not feline children. I guess we didn't read the fine print.
