we're baaaaaack

Cats are insane this morning. I thought it was just because we left them, but now I have my doubts. Was just sitting here posting about the weekend and finding it very difficult to do so since my cats won't stop making noise and pouncing on me. Then I hear Mia hissing and caterwauling in the other room. I walk in and see her standing by the scratching post staring up at thin air and wailing. I walked toward her and she backed up frightened, which is very unlike her. Picked her up and she's trembling. Then, all of a sudden, something tugged on my shirt from behind several times really hard. I turn around, nothing's there.
