I don't know if this means anything, but this morning my cat is acting very strangely. First he tried to hide in closet and under and behind stuff, looking out with kinda freaked out eyes. He usually hides when he wants to sleep in peace. I weaseled him out with a treat, which he ate. Then he strated to walk around, wag his tail alot and briskly, like he is nervous. He stares at the window, but he is not at the windowsill as usual, just stares far away from the floor, and reacts to the slightest noise, he points his ears, turns head, etc. He just acts like he's seen a ghost or something. Otherwise, everything else is normal, except his nose is warm. I read the whole nose-cold/warm indicator is a myth, but still. He just looks really nervous, I might be overreacting though.
