Biscandmatt ~ they are bonded (blood, sweat and tears!).
I bought Poppet the lop along with a hutch that the petshop said would be a good size for two buns (I was waiting for Cookie, the mini nethie from the same breeder/shop).
Cookie moved in to ours a week after Poppet, and Poppet took an instant dislike to the newbie ~ so a second hutch was promptly purcahsed. They were kept separate, and it took us three months to get Poppet to accept her new mate.
They have since been spayed and the idea was for the two to live together (that was always the idea - just took longer than expected!). I quickly realised that the hutch I had originally bought was too small for two, and when I decided to buy a new, bigger one for Cookie and Poppet to share, grand-bun decided to build one.
Cookie and Poppet have been living indoors (free ranging) since their spay in January and don't like to be apart now (but we still have the two hutches if I need to put them away for a few hours). I want them to share the new hutch when no one is at home, which won't be too often.
But now I do worry a little - they are not big buns by any means, but maybe hutch is too small anyway? I will get measuring tape out...
