Hat is upset about Kiki's continuous presence in the house.

And one morning Sister S woke up at 4am to close the shutters, to prevent Kiki from jumping in.

Hat tried to enter the house by jumping in through the windows, and of course was hindered. Sister S said he heard Hat banged his head 4 times on the shutters, between 5 to 6am.

Hat finally managed to come in by 7am, and prepared to sleep on the sofa.

But Sister S wanted to eat her breakfast there, and Hat was all tensed up. He left after Sister S put a cushions between them.

Sister S told me Hat is indeed a very strange cat.

Hat somehow worked out that Kiki is the source of his problem, so now he avoids Kiki like the plague. He even refuses to eat in the kitchen with Kiki, he rather satys outside.
