Vet appointment was this morning. Last night was the first night (again) of trying to stop giving the Cerenia, so paws crossed for that. She didn't see a need to re-check fPL levels right now based on how he's feeling. She did notice he has a tooth resorption on one of his tiny bottom teeth and another that the crown is already gone. That tooth hasn't been there since he was diagnosed, I'm pretty sure but the bottom one is fairly new. I just checked his mouth a week or two ago. Suggested in 1-2 months getting him in for a dental if he's stabilized.
Took him down to see the Cat hotel area, he hissed and growled in general

. The girl said most cats do that but I haven't seen Maury react that way before so my hopes are not so great for that. Imagining him stressing out like that for 4 1/2 days breaks my heart.
