My rabbits around 20-30 we had him for 3 years and this behavior happened ever sense we got him! He was a returned rabbit who was returned because he had behavior issues around another rabbit and bit the other rabbit so we took him because my first rabbit died at the time and i was slowly getting mentally exhausted my rabbit has never been neutered nor do we know if he really IS a boy. We dont trust the vets near us because when we took my old rabbit to the vet it was always a struggle. I want to make him a free roam and i genuinely dont want him in his cage anymore and when i do get him out he gets upset. His cage is very big and he eats and drinks water all the time but i genuinely dont understand why hes so aggressive we tried a lot of things we even made a theory that he was malnourished at his old owners house and thats why he became aggressive towards theyre rabbit and feels the need to still be like that to get his way but i genuinely dont know hes such a sweetheart and i genuinely love him so much but i want to help him with his anger issues in a way is there any advice to get him to calm down a little? :]
