I get home a couple of minutes ago and Tai doesn't even come off his sofa to greet me. When I cuddle him, I get a meow that goes right through stone walls. I checked him, but he seems quite fine to me. I emptied his litterbox and he's been using it, so it seems internally everything is fine as well, though that may be just an assumption of me.
He certainly ain't as active as he was yesterday, but I can't figure out what is wrong with him. I'll head off to bed and check again when I wake up. Maybe he's just in a bad mood coz I woke him up too soon?
