I have 12 week old male Lionlop that is very aggresive while he is in his cage. When I feed or put hay in his cage he lunges at me (ears back and tail up) and trys to bite my hand. But when I reach in to pick him up he just sits quietly. Oliver only shows aggression when I am moving something in his cage or when I feed him. I don't know what to do? I am hoping that neutering him will stop the cage aggression but thats 2 months away what do I do until then?

Sounds like he is just getting to the age at which male rabbits can get very naughty.
I think you need to overcome this territorial behaviour quickly and the best way to do it is to spend a lot of time with him and handle him gently but as much as possible. Also neutering at the earliest possible opportunity it can be done from about 16 weeks may help too.
