Sounds normal at least!
And for everyone suggesting evening feeding and warming the food--I do already do both and have been since I first got him. I'll usually put his rat in a cup of warm water and let it soak for a minute or two until it's around 98F before offering it to him around 9:30/10PM at night, so that if's he's having a 'shy eater' day I'll be heading to bed soon anyway and he can eat in peace. I've tried dimming the lights before too, but it doesn't seem to make a difference for his enthusiasm (or not) for dinner.
I can definitely work out though so waiting for him to decide to eat doesn't tire my arms out!![]()
