• Should the sink have an overflow path in it. Come to think of it, my bathroom sinks do but not my kitchen ones.
• Change the faucet to one that has turn knobs so it's harder for them to turn on.
• Get a water alarm. Possibly a smart one in case they strike while you are away.
• Get a dog, get rid of the cats.
