Cat Face is not at all sexist.
This may be my favorite episode from the series so far. It was nice to see the shopkeeper returning from the previous episode. I love whenever Cat Face yells stuff at the waving school children, he is reaction is great. If I am correct, this is the first episode to get a weekly award, and it is fully deserving. Plus I do not believe I had heard Cat Face swear until this epsiode, he is a filthy cat (in two different ways!).
I didn't have a long glance at the end screen, but I noticed there was a different cat bu the replay button, maybe a hint towards a future episode? I liked the newspaper part too with the article about PoshTom. The shopkeeper's trick was a clever one, it even outsmarted Cat Face. Another impressive episode completed, keep up the great work!
