I finally managed it, I left them squashed up and just extended the bit that needed to be screwed in so I could still get my hand inside. I thought my bf was going to freak when he saw this big green thing on the roof terrace but he just said he was jealous and wanted to be a rabbit :lol:
They haven't tried to chew it so far, they've had one of those Tesco tunnels for a while and haven't chewed that, only the llittle balls on the inside were chewed off, I don't think it will last much longer though, its a bit weather beaten which is why I bought them the snugglesafe ones, three tunnels and the interchange cost £30 from vetuk.
Poppy has been using it as an escape tool when its bed time, I approach her and she goes to one end of the tunnel then out the other or sits in the middle so I can't get her, cheeky little madam :lol:
