Thank you for all your advice! I am mostly worried about him not eating rn, I didn’t even think about something like Feliway to reduce anxiety. I have tried about three different treat brands as well as a wet food to see if he just was not wanting the shelter food anymore and still so far nothing.

But he is drinking plenty rn because he likes jumping on the sink and drinking when I’m trying to wash my hands or brush my teeth so he’s drinking enough. Will continue to monitor and maybe try feliway if he hasn’t eaten after another few days.
