my 900g+ mouser, after a year has finally gotten his appetite back, the last 4 weeks he has been eating a small 25-30g mouse (which is all he eats) consistent and quickly every 3-4 days, as opposed to eating one every month or two, and yesterday he was the most aggressive ever, he took the mouse down quick and then kept his head out of his hide looking towards the front of the enclosure (his usuall sign that hes hungry) for hours after that. Right now he is in his hide, but my question is the following.

1. I want to take full advantage of this, i feel he is underweight, and how bad would it be if i fed him again today? (just this once, next time, in 5 days i will try 2 mouses)

or

2. should i try and throw in a rat? i feel like i should, but then again i remember trying this a year ago in a time when i knew he was hungry and i threw a rat in there and it made it worse, instead of eating (if it was a mouse he surely would have), he got more turned off to the fact of eating and made his hunger strike last longer than if i would have just gave him a mouse.
