Highlights of the Study (in a nutshell!)

The bottom line is...

If each pet cat in the U.S. kills 4.2 birds per year, and assuming, conservatively, that half of these cats never leave the house, at least 134 million birds die each year due to domestic pet house cats. This figure does not include stray or feral cats, which would greatly increase this figure.
