For a while, my bunny had a traditional hutch which he liked, but the Zippi Tunnel system brings the housing to another level. I would recommend this to anyone. My bunny has figured out how to go backwards through the tunnel. The tunnels feed to an extra playpen which is perfect. If you get the tunnels, the playpen is a must.
It’s been a long haul, but I’ve finally got there. We have 2 Dutch bunnies who are separated AFTER getting neutered but like seeing each other. They adore their Omlet outdoor run plus eglus (hate being inside), but need to be in a double hutch in the garage in the winter cold. I have finally set up a divided run with a tunnel run each to the (early) Omlet play pen across the single garage width. The tunnels actually only bend slightly, and those 90 degree corners and angled connectors are very important. The smarter shyer bunny is in the top half of the hutch, but has no issues with scrabbling up the ridged tunnels, which have to be on a diagonal (took him 5 minutes of testing). I am now debating whether to cut down a length of tube so that the full garage width is exploited. I’ve learned that you should always install a full closing door at the ends for isolation, and should have an unistalled door or a connector with a homemade blanking plate for adjustments. The bunnies went from sulks to joy instantly. Come summer, the whole tunnel system moves outside to the lawn.
