Well, I guess when I started fostering and getting more rabbits I never really thought of any bonds being broken (I had bonds form though) and none of my bonded pairs ever started having problems – I guess ignorance can be a good thing sometime.
Now, I don’t have any other species in my home other than a noisy cockatiel so I cannot speak to the species thing – I have though at times had hamsters, mice, and guinea pigs with my rabbits and obviously no problems there.
I have all my rabbits in one room too housed separately in xpens or Leith condo’s – have always done this and never had problems – even when I had unaltered rabbits with my altered which was going to happen. I’ve heard of there being problems though but never experienced this myself.
At the sanctuary I help at we have altered and unaltered together too and pairs, singles, trios – I don’t observe any problems there either.
