you need to neuter him....
he will be less aggressive..but certain breed.... no matter how you neuter
they will also be aggressive...especially those local cross breed like mine ....
you can train them but it is very hard.......did you buy when the rabbit is small?
wow your rabbit jump on your sofa.....- cool........
my one jump until upstair :)
but they never poo in my sofa because i always supervise them
never near my sofa - because i chase them away....
i got two to control.....
but my darling eldest no need..... he wont pee nor shit anywhere unless he goes back home
