It has been a while, so I thought I would give an update, Benji had been quite up and down but we thought he seemed okay through December, the idea of putting him down wasn't in the discussion; mid-late dec his terbutaline was all finished and my mum went into surgery so ordering more never happened although we aren't convinced it made a huge difference. In London, it reached -4 degrees, and although rabbits can survive in colder temperatures Benji passed away on Saturday morning as I found him lying just inside his hutch at the entrance. I'm very heartbroken as I never really expected to find him passed away, and I don't think it's fully hit me he's not coming back but I feel so sick just reading what I've written. Hopefully, I can upload a photo as he was such a sweet little rabbit and so cute. We think ladies a bit depressed as she has been avoiding the hutch (which is a double-decker) and we aren't sure if it's because she saw where Benji was lying. We contacted the breeder we got him from and told her the news but she has 2 more boys who are around 7 months old that we could have I want both because although they don't live together I'd feel awful leaving one behind as I've grown attached just through pictures of them but I know it might be hard to bond 3 rabbits all together and I'm not sure if two will bully the other. Lady is very dominant so I don't think they could bully her but I just need some advice as I want to give the best life possible to my future rabbit/rabbits because Benji never got an easy pain free life. RIP baby Benji
