I haven’t read through the recent posts but ... I’d feed over a piece of card to minimise the chance of ingesting substrate.
Also feed in the evenings, low /dim light .
I find it best to wait until they’re settled UNDER a hide then a quick blast with a hairdryer and dangle it whisked it’s still warm in front of the hide entrance.

Is it necessary to put something under if the rat isn’t wet? Also, most have said it didn’t matter where he is when you feed, but he’ll most likely be in his hide when I do. Thanks
