Siu Pao had just been de-worm a week ago because he had worms and his poop had just clear up and start forming normal stool. I have tried my best to clean and clean and clean his stool when he had worms and until now because I don't want him to re-infect himself. I didn't sleep for 2 nights due to him having diarrhea and I wanted to clean his poo. Today, right after he poo, I was going to clean up as usual and he knows I forbid him to eat his own poo but he took one and ran with it and by the time I got to him, he ate it!!!!! I am so angry at Siu Pao right now

Will he be re-infected with the worms? He is getting a second dose in another 2 weeks but I am worried the worms episode will go on and on.
