Gabriel (see icon) has taken a sudden and violent dislike to the desk where I keep my laptop. When I am working there, she comes over, tromps all over the keyboard (with unfortunate results), hisses, growls, and attacks my hands with teeth and claws. If I move to my recliner, she'll often settle into my lap and purr, even if I'm working on the computer. It's the desk she hates and maybe fears.
We have had some changes in the household, but none recently. I also have noticed the other cats are on edge a bit too. Earthquake coming?
She is 12 years old, no changes in food/water intake or outgo, no lethargy -- she's just lost her little mind. And I don't know why.
