Feeding youngster.

I've recently gotten a snake, hese a young one arround 2-3 months. The guy at the store i bought him told me to feed him every 3 days. I've fed him friday with a towl over a little basket. I've tried feeding him without a towl today but still outside his cage. He wasn't very happy as i had to get him out of his plant ( Got rid of that now ) but he just went biting at it, he didn't actually eat it.

Then i've tried doing the towl trick. Nothing. He just won't eat. He just went stressing arround, right now hese lying on the bottom of his cage under inside the soil i use. ( Snake Bedding )

My question is, should i keep feeding him every 3 days or should i revert to the 5-6 days plan??
