I'm sure he will be fine, I would give him a bit longer to digest before you feed again.
My GHI is my trashcan, she eats any leftover rats I have due to refused feedings. Once I freaked out because she ate a Medium and a small rat, but I had an extra Medium rat that I couldn't convince my picky eater to take. Well my GHI was staring at me from her tub after finishing her second rat so I jokingly swing the extra medium rat towards her and she took it too! She was about 1400-1600 grams at the time. The only repercussion was that she woke me up in the middle of the night a couple weeks later when she was ripping major farts and dropping a massive poop.
And thus she earned her name, Big Nasty![]()
