Thanks everyone for the replies! He is doing well. I lowered the temp of the UTH a few degrees. this morning there was urates and a good amount of liquid too. I felt bad bothering him to change the paper towels, but it was fun to hold him for a minute! He is definitely more responsive than he was a few days ago.

If he comes out looking for food after 4 days I'll offer it, otherwise wait til day 5. Taking care of him reminds me of when I had my first child...always worried he would stop breathing when I wasn't looking LOL

How often should I weigh him to check his progress?
