Well, my cat catches flies in mid air and is an excellent hunter of spiders.
Unfortunately she is too well fed to be any use with mice. She just played with one the other night until it escaped, although I don't know if she would act differently if I wasn't watching. Perhaps if I'm not there she would kill it and leave it for me to find so that I would know she wasn't sleeping on the job. :)
There is an interesting theory on this - read it in a book, so it must be true :)
Kittens play with everything and "fight" eachother to improve their hunting skills. At some point their mother will bring them live mice and possible other animals as more challenging targets. If the mother is a well fed cat, she will just let her offspring play the mice to exhaustion/death. But if she needs mice for food, she will teach how to swiftyly execute the prey - i.e. the killer instinct.
As your cat grows up, well fed and happy, it will notice how bad your hunting skill are. It will, as a token of appreaciation, try to teach you as it was taught - by bringing live animals into your house. If it was never taught the killer instinct, it will just set the mice free and show you how to catch it -- until you learn.
While my hunting skills will never be anywhere near those of my cat, they have improved a lot. I can usually catch a half-beaten mouse in 10-15 minutes. I have also learned to catch the mouse by the tail. The mouse will defend itself and it has very sharp teeth -- right into your hand.
