I feel like depends on the cat. I found mine as a list kitten that we assumed got outside and then was starving and almost dead. He's always been N indoor cat. Had never seen a mouse in the 8 years he was alive. I go out of town for a day and night and come back to a decapitated mouse in the apt. Fool took care of shit without even knowing. Then years later, we move into a house and a mouse gets in some how. My cat finds the mouse, kills it, walks around with it, then drops it in the hallway for us to clean up. If he had been taught how to catch mice when he was a kitten, I he wouldn't have been starving to death. But when a mouse showed up, he knew exactly what to do.
