Aaron pointed us to Cute Overload. It seems to be a mix of genuinely cute stuff and kind of creepy Beyond Ubercute stuff and kitschy quasi-cute stuff. Although I suppose the lines between those categories are different for different people. At any rate, there are some phenomenally cute photos of adorable baby furry animals and such. A couple of examples: Sugargliders (1st photo cute; 2nd photo cool but kinda scary); chipmunk eating peanut practically half its own size.
And Adorablog linked to The Daily Kitten, which I've linked to a couple of times before but I think it's a requirement to include a link to that anytime I'm posting links to cute photos.
