Not much of one at this time, unfortunately. He's still giving them hell (by the sound of it, making their job a bit difficult), bright and energetic. He threw up some of the activated charcoal overnight (not all, but some), hes lost a little bit of weight as would be expected. Didn't eat to much, but that's also to be expected - they probably fed him pellets which he's not crazy about.
They are waiting until later today to do the bloodwork. Its takes 24-36 hours for liver and kidney symptoms to manifest, and since he's still looking good they want to err on the longer end of that spectrum before testing. Possiblity of staying one more night, depending on how everything goes.
