The blood work came back, and indicated there might be a problem with Percy's liver. We're to watch the kitty tonight and see if he's eating, drinking, and using the litterbox, then call Sat morning first thing and tell the vet how he's doing.
It might be nothing, or it might be something.
Percy still was a normal temperature this morning and paying attention as I walked through the house, but he didn't move from the spot where he was napping. He did stretch and turn over a few times, but he stayed right where he was. He missed his morning feeding and was still sniffly. I guess he just wasn't hungry.
I hope it's nothing big.
