I recently discovered Gato Poder, another super-fabulous cat-centric blog. It's mostly art oriented but there is a fair amount of wacky youtube clips and weird t-shirts and records and what have you. Here are some of my best finds:
Allison Edge (that kitten's expression is priceless)
Plastic Sarah (Joanna also has this t-shirt. I am so jealous!)
Freddie Mercury with cat. Awwwww....couldn't you just die?
