...another possible solution is that if you are traditionally letting your cat out to roam at night, and he sleeps in during the day, you can try to reverse his habits, and let him out to play during the day, and then bring him in at night...the small rodents that cats like to catch are usually most active at night...so cats tend to have a more "successful" hunt if he is let out at night...during the day, those rodents/birds are usually hiding out somewhere anyways...

You are lucky that your cat is bringing home animals dead...their hunting abilities will improve, and in the case of my cat, she is bringing home small rodents alive...my cat usually breaks a leg or does some sort of damage to the rodent so that it is not completely dead, then presents the rodent to me early in the morning, and allows me to inspect the fact that she was able to catch the rodent but not kill it...she allows the rodent to wearily run around the kitchen, at the same time keeping it under control for me to watch...then, I give her breakfast and then she forgets about her new found toy, and I end up having to do the dirty work of putting the rodent out of its misery and burying it somewhere in the yard...squirrels, crows, mice, etc...I ended up letting her out during the day and putting a bell on her...I hook the bell around her collar and take it off when she comes back in the evening for dinner...she may not like it, but I don't exactly like cleaning up her work after her and mopping up blood trails all over the kitchen floor...
