Bully

Kalle (up front) was sleeping, when suddenly Junnu showed up
and patted his face. Thereupon Kalle flattened his ears and
seemed to wait for a coup de grace. Junnu patted his face
another time and then took off.

To my observation, this kind of behaviour is an about-weekly
occurrence.

For any cat, living in a group of five is an occasional challenge.
They can form 5!=120 possible combinations in relation to
each other.
