My cat is staring at the wall constantly - why?
I have three cats. One, a male black shorthair, is starting to act rather oddly. He's starting to stare at the walls.
Normally this wouldn't be a problem. However, it's gotten so bad that we had to move his cat perch away from the router, because we thought he was going to jump on it to get at the wall. He is now trying to sit on me/my computer desk to get closer to another wall.
The odd thing about this is that he is the only one staring at the walls. The other two cats act like nothing is there at all. Nothing IS there, either, including no sounds and no cracks.
He is only staring at specific places. At first there were only two in the living room: one behind the router (which might have lights from the router on it, though I can't see them) and one next to the kitchen, which as far as I can tell has no light on it whatsoever. It has the unmoving shadow of a fruit basket, but I can't imagine that would be it. He now stares at the wall in my bedroom also, trying to climb on my computer desk like I mentioned. There is some light from the shade on this wall in the early morning, but otherwise it is extremely nondescript.
Why is my cat doing this? He is acting as if there is something on the wall that he can't quite see/hear, but knows it is there. As if he was chasing a laser pointer, but toned down by about a third.
You mention unmoving shadow and a shade of light at a specific time.
This reminds me a lot of my own cat.
He has always had a fascination for these things and a keen memory for it.
He always comes sit with us at the dinner table, because the light reflects on our knifes against the ceiling, he loves this and whenever we eat, he will sit and stare at the ceiling, even if there is no reflection "active".
He also spots any other reflections nearly instantly.
He also loves moving shadows. Is the fruit basket always there? it could be that he is intrigued by the "new" shadow on the wall.
My other cat who is 1 year older never shows any interest in any of these things, he will not chase a reflecting light on the wall or ceiling and cares even less for shadows.
So interest in things depends on the cat.
I wouldn't worry to much about it but i understand you as an owner, you have to remember that these animals do not think like we do and that everything new does not have a simple explanation for them.
We know at night that light from outsides comes from cars, streetlights or even people. Cats do not.
