Holding a grudge
Nobody, we repeat nobody holds a grudge as a cat does. They do not believe in forgive and forget things but in turn the other cheek lifestyle.
We totally are on the side of this adorable kitty.
This annoyed kitty has a justifiable reason for having that dreadful gaze at his owner. How can the owner enjoy his dinner when his doggie friend was robbed of his food, and not given any compensatory meal to make up for all that happened? Appalling, isn’t it?
