Regarding your article on how many birds are killed each year by ordinary house cats, when our cat was alive we put a tiny bell on her collar so she could explore the outdoors while giving birds plenty of warning that she was close by ("The destructive invasive species purring on your lap," Feb. 26).
It was extremely effective at preventing her from killing birds. While I'm sure a leash would have been more effective, the practice seems unlikely to take hold any time soon. Bells are easy to use and are found at local pet stores.
