Испанский вариант: «La curiosidad mato el gato”, но похоже, что испанский кот пришел из Англии.
"Curiosity killed the cat" is a proverb used to warn of the dangers of unnecessary investigation or experimentation. A less frequently-seen rejoinder to "curiosity killed the cat" is "but satisfaction brought it back".
The original form of the proverb, now little used, was "Care killed the cat". In this instance, "care" was defined as "worry" or "sorrow."
