I recently went back home for a few days. A neighbour’s cat had given birth to four little kittens. Once I woke them up and one of them was really pissed off. I have never seen so much anger and a look of annoyance in a cat before! (S)He looks like he is saying: “why did you wake me up you*&%$?”. By the way, from another picture, it seems that this particular kitten has a mustache!
