Lolcats
In talking to vespertila I discovered that she had never heard of http://icanhascheezburger.com/ and this just a crime. So I sent her to the site. It then occurred to me that there might be some other poor soul out there that hasn't been the this bastion of amusing cuteness, thus I figured maybe I should post the link here.
In the same vein, I suggest checking out baaaaabyanimals LJ comm for even more cuteness.
Enjoy!
