Ok, so I know every cat has their "crazies" but I can't tell if Mac is just exhibiting normal cat behavior or if something is really scaring him. Every night about 9 or 10, he does zoom around my apartment from place to place. It also happens in the afternoon sometimes. I've seen other cats do this, but Mac seems actually scared to me. His tail is fluffed or down, his ears are back, and his back is arched. He's not aggressive, and he's usually ok if I approach him. He also makes pitiful meowing noises. I know he might be part siamese but this is really the only time he vocalizes. Am I just being paranoid or is something in my apartment really scaring him? I found some youtube videos with music for calming cats and this seems to work but usually by this time at night I'm getting ready to go to bed or watching netflix or something so I can't always play the music.
