Slight aggression signs?

Okay, sounds good ill start buying larger Rats, thanks everyone.

I agree that he's probably hungry. My females get like that after laying because they are starving and trying to put on weight. You may need to up his prey size. Ball pythons aren't aggressive and they almost always calm down with age, I've never had one get "meaner". I also feed in the enclosure every time, you can't "train" them to be aggressive by feeding them in their enclosure.

Sounds like he hates you,lol..hope this is helpful

just kidding,apparently he is stressed,maybe hungry..how often you feed him
