We've had 3 birds hit our windows in the 12 years I've owned this home. To combat that, I made sure all the windows had blinds. It hasn't happened since. My one neighbor's cat kills more than 3 birds per month in the warm seasons. I haven't been able to combat that unfortunately. But I did build a dry stack retaining wall that has allowed the chipmunk population to have a bit of refuge. They are slowly growing in numbers. We had scores of them until the neighbors moved in next door. Within months they dwindled to less than a dozen. My wife and I used to love to sit at our breakfast table and watch them scurry around the yard and patio. Our neighbor's cat ruined that for us. I shouldn't have to spend $5k+ to prevent cats from killing chipmunks, but I'm always willing to do whatever I can to improve something rather than just complaining about it.
