Not all cats run and hide when they hear the sound of a can opener. While it's true that many cats associate the sound of a can opener with the opening of their food cans, not all cats have the same reaction. Cats can have different personalities, temperaments, and past experiences that influence their responses to specific sounds.
Some cats may indeed become excited or eager when they hear the sound of a can opener, as they have learned that it signifies the arrival of their food. They may come running or gather around their feeding area in anticipation.
However, other cats may not have the same reaction. Some cats might not be as food-motivated or may not have been conditioned to associate the can opener sound with their meals. These cats may not display any particular response or may simply show mild curiosity without running and hiding.
It's important to remember that individual cats can have unique preferences and behaviors, so their reactions to specific sounds can vary.
