The hutch in question is actually a two storey 6x2ft that we already own. We are removing the ramp and purchasing a trap door to turn it into 2 seperate hutches. This after a tragedy we had last year with our rabbits.
My ramp was adapted - it had high sides to prevent bunny falling off the side and had extra grip bars to normal for added grip. Last summer our bonded pair started fighting horrifically (a very small wildie had got into the garden under fence - that's the only trigger we can come up with). So any way we hear all this commotion, go outside find them figthing like crazy, fur flying every where. As we approched we saw Poppy slip at a slight angle on the top of the ramp, as they were fighting. We managed to grab a bunny each. When we checked them over it was clear that poppy had severely broken her leg - we don't know for sure it was on the ramp, but it seems the most likely. Unfortunately she passed away during the complicated op to repair the damage.
This event left us somewhat traumatised. We couldn't bring ourselves to get a new companion for remaining bunny Burt, but knew it was not fair on him. We talked to the rescue who took him back and rehomed him with a new companion, with-in a week. We miss him dearly but even now a complete year later we are a little worried about getting another pair. But we both agreed we would never have a ramp in a hutch again. So we are splitting it in two. Hubbys said hes happy for me to put piggies on top floor and we are going to keep the bottom hutch empty, until we decide on more rabbits or not.
