Ok an odd title I hear you wondering, but a good one. Currently I can has cheezburger is my favourite site - I go there every day, sometimes twice just in case they have added a new picture!
It's a great site, dedicated to silly animal pictures (mostly cats but sometimes other animals creep in) with funny captions that are written in catspeak.
Some days I have cried with laughter over this site, it just cracks me up. and Laughter is good for the soul - so go and check it out now - and bookmark it, and visit it every day!
Here are a few pictures to show you why I think this is the best site on the Internet right now!
