Domesticated house cats love to stalk and capture prey. Some are prized for their mousing abilities, and love to go after birds. In fact, some people are concerned that cats may be responsible for the deaths of millions of song birds every year. And just how many? Well, the Mammal Society of London recently did some research on this very subject in Great Britain. Michael Woods led the project, and he says a large number of cat owners reported how many animals their pets caught and brought home over a five month period. Steve Curwood talks with Mr. Woods, the “Sherlock Holmes” of this murderous puzzle.
