How often has Sylvester killed Tweety?
by Judith Webster
The summer 2009 edition of B.C. Nature included an article
entitled, “Cat licensing: A conservation strategy that can work.”
As a cat and bird lover, I was inspired to investigate author
Sherril Guthrie’s claim that cat licensing and confinement bylaws
would “protect and restore our bird and small mammal populations, as
well as return cats to their rightful place as valued pets and
companions.”
Guthrie relies on American Bird Conservancy “Cats Indoors!”
campaign literature, which includes too many disputable studies,
extrapolations, and anecdotal reports to delve into deeply here.
However, in her strong opening paragraph, Guthrie discusses a new
bird count analysis by the National Audubon Society revealing that 20
of North America’s most common birds have lost over half their
population since 1967.
