From Michael Cristina:
Re: Domestic cats seen as major killers of wildlife (Jan. 29, 2013): The amount of birds and small animals killed would be put into better perspective if you estimated the number of “Free-ranging domestic cats” in the US. That is, how many kills per cat per year.
Also, how many killed per year vs total number of birds and small mammals in the US.
