runaround for Giants

Hi there I really like the look of the run around system. Has anyone used these with larger rabbits. My rabbit Peter is a flemish giant but hes not actually that big. I dont think hes reached full size yet. Just thinking if hed get his bum and ears stuck in the tube!!
Thanks

I have 2 contis and they couldn't get through the normal runaround I don't think once they are fully grown but they do a bigger rigid, straight pipe called a den pipe which they fit in easily.

My conti has a straight cat tube from p@h - that's fine and he loves it. Not sure anything smaller or more twisty would be ok. :thumb:
