I am almost certain Tiger just wants to play, but Cleo and Pole don't know this and they have been running away from him since he started chasing them.
But there is not even the slightest hint of aggression from Tiger, so I think he just wants to play.
This is typical daily scene; Tiger wanting to play with Cleo, but soon, Cleo would be running away to hide under the bench.
This morning, Bunny was in a bullying mood...
I want that chair!!
I think I saw Tiger hissing back.
Gimme that chair!!
I intervened to stop the aggression and....
Bunny went to distract himself.
I can sit here, can't I?
Of course you can, Tiger!
Don't worry, I'm keeping an eye on things.
Tiger comes under my protection.
