I'd fill out the ask for help form just to make sure everthing's ok but often around this age they get bored with food. What all different feeders are you offering him? I would not offer him anyhting else today and wait until tomorrow afternoon before you offer him another feeder and then just off him one to see if he's eat it. This is about the age to start feeding every other day. Post some pictures of him please.
Dont freak too much. Mine is 9 1/2 months old and did not eat for a few days either and then he did. If you determine that their is nothing physically wrong with him, then like Jann said he might be bored with the food. so maybe try offering some different things. I have been feeding him every other day and he seems to be way more hungry now on the day I feed him.
