International Cat Care - Free PDF book online:
International Cat Care (formerly the
Feline Advisory Bureau.
http://www.icatcare.org/what-we-do) have on their
website a free download of a very useful small book on cats and
"owning" them called "Essential Cattitude: an insight into the feline
world":
http://www.icatcare.org/sites/default/files/PDF/essential_cattitude.pdf
It's ideal as an introduction to cat "owning" for people new to
having cats but we can all learn something from it!
