I am an avid reader of Salon. Heather Havrilesky, the television critic, is sucha a talented writer that I read her regularly even though I do not watch television! I was going to cut and paste the kitty-related parts here, but since they are interspersed throughout the article I decided to just post the link. When you first log into Salon there is a short ad to read first if you are not a paid member, but it only takes about 15 seconds.
