HELP! Suddenly Weak Ball Python

[Kiyayiya]

OK, since I tried feeding yesterday, should I try again today? He was SO CLOSE yesterday, seriously. It was the first time he's shown any interest in all this time. When he yawned I thought for sure he'd eat...

I know as worried as you are it may seem like a good idea, but you would probably just wind up stressing him out more. I think you should wait at least another 5 days and try again.
