I suppose everyone knows about this, but I had to blog about it because it gives me so much pleasure…

You can subscribe to cat pictures on Flickr using Bloglines/Blogroll/whatever RSS, XML or Atom feed reader you use. I get my daily cat fix from this, since I am allergic to cats and cannot get any closer to them than this. Sniff.
I also subscribe to crochet pics on Flickr so I can see what other crocheters (non-bloggers, sometimes) are upto.
