Congratulations! We know how good this feels!

BTW, I had various pet rodents for some years before getting into snakes "accidentally", so I (& some others) do understand how that feels too...

Personally, I'd go ahead & let him wait at least 5-7 days before giving him another prey item. He may or may not take a second one right now...it's surprising how
some snakes just won't eat 2 at a time, no matter what size. And he won't starve in a week either...snakes are designed to NOT eat all the time. You did good!
