agressive 3 month old rabbit

Question
I just got a 3 mnth old bunny from my boss as a gonna be first pet for my 3 mnth old and when i first got him he seemed fine with me and my cat , they would actually touch noses and walk away , but lately he (they said he's a male# has been chasing my cat around and attacking him , my cat has not done anything i have seen to instigate this behavior #he/bunny did not have a cage yet so he was roaming the house) he now has his cage but it has escalated to him biting and trying to attack us also . I have posted him on craigslist but if there is any way i can correct the problem i would love to try . any suggestions ???

Answer
hi -it will be hard to get him to get back to how he was -he is just showing you all that he is the dominant one in the house.
pick him up every day and groom him -it may take a few weeks but in the end he will come to accept you and become more friendly .
not sure about the cat but just see how it goes.
