The neighbour cat spends ages in my garden in hunting postures staring at insects and occasionally chasing them. Then she'll lie down and enjoy the weather for a bit,continue her patrol and come back a couple of hours later and repeat.

And when I was a kid we had a cat that we eventually discovered liked sitting in the berry bushes in the garden and kill birds. We discovered it because she didn't eat them, but just left them there and we eventually found a whole pile.

She did on occasion hunt for food too, but mostly when the prey was out of the norm, like once when she caught a large rat - only the tail was left. Of course I don't know how much she ate out at night, though.
