Andrew Stack has filmed his cat exploring the world in all sorts of ways, whether he’s learning to use a kitty toilet or watching birds on television. Although Leo is clearly a curious cat, he still has a fear of the unknown. This video shows Leo testing the boundaries of a circle Andrew has made using tape on the carpet. Most cats seem happy to explore, but not Leo. We can only guess why he decided it wasn’t safe to enter. Credit: YouTube/Andrew Stack
