I have my Mister who is a (practically ) whole house bun. I began fostering rabbits & I found a little girl I want to keep. Mister is 2 yrs old and neutered since his youth. This little lady is about 4 months now - so maybe spayed in another 1-2 months depending on vets advise . I am SO anxious to introduce them to see if they will get along. Mister doesn't seem to be happy when I have other buns around (as I "socialize" them - so even though they are kept elsewhere in my house - he gets a whiff of when they've been allowed out - especially on my deck outside) - so I am going on the assumption HE will be more the problem when I try. Any opinions on timing? I realize that rabbits can change after they are fixed....also that they change as they sexually mature. I am wondering if maybe bc she is a little younger he may be more apt to accept her (and her not to be too much an aggressor) at her age? I know SHE may change, but are my odds better with HIM with HER at a younger age? On another note - I am learning SOOOOO much from my fostering - and I have "higher ups" that have taught me so much - we don't do quite as much in the "bonding" dept though. I can't wait until I can get the time to help out many of other new combers.....I just think this is SUCH a great forum - and works in the best interest of the buns!! I think I could offer some good advice - just life has been a little too crazy with the hooman family lately - but I would love to be able to share what I've learned !
