Cat population density chart

I collected as much data as I could find today about cat populations in order to show the relative popularity of cats around the world. I was hoping to find data including stray cats, but that pretty much doesn’t exist.

What I take from this is that Germany and Spain are particularly cat-hating europeans, that the United States is aberrantly cat-philic (and are infecting Canada), and that Japan is not nearly as cat loving as I had thought from cats’ presence in their pop culture. 

I don’t like the way Google Docs does footnotes in published spreadsheets, but they are all there at the bottom.

No word yet on the cat populations of antarctica or space.
