websites for cat owners

or I should say, for cats' humans!

these were in the back of the new book I just bought, good catkeeping

feral cat coalition http://www.feralcat.com

do I need to put the "http:" part before www?

www.cats.org.uk
www.acmepet.com/feline/index.html
www.thedailycat.com
http://www.1888pets911.org.
http://21cats.org

has anyone seen those things, ID tags.com? has anyone joined online to that? I saw it at the grocery store, a tag with a website listed where you go online and subscribe to it, supposed to help find pet that gets lost.

does anyone know of other websites or places that help find lost pets?
