How can I discourage my cat from bringing me LIVE gifts?

So yeaaaaa…. got no problem with him showing his love for me by bringing me a mouse/vole/chipmunk/whatever, it is a problem however when he comes inside and drops a live mouse/vole/chipmunk/whatever at my feet. I could always just keep him inside but I think its best that he has time to get out and explore outside. Any way to discourage this sort of behavior?

The current tally is 5 mice, 1 chipmunk, 2 voles. Getting a bit tired of having to catch these critters running around in my house lol
