We live in a very mild tempered part of central California, I would never leave my future bunny out in the rain, or on an abnormally hot day. Our town also seems to have a feral rabbit population, not that that has any contribution to the tolerance of a house bunny. (or that they could get into my yard, I’ve never seen one) Although, I might be getting a rescue, but I still don’t think I should take any chances and treat it carefully. Like I said before, I’d only leave him outside on days I can check on him, and when the weather is good. Never over night, never while I’m out.
Also, I have gotten a few suggestions for types of wood from other sources, one person said Poplar, but my step dad, who is helping build it, said that is very expensive and suggests Hemfir. I am willing to pay more for better wood if necessary, but i just really want to make it safe for mr bunny. I have heard not to use any seals and to only paint the outside as bunny will chew the inside.
I also suppose I should mention, I have a family friend who owns a bunny who lives mostly outside. He started as a house bunny, but they found out she was allergic to him. So they made him a very cozy large gated area for him to live in. I haven’t visited them in a while, but last time I did the only possible hazard was the bunny burrowing. He wasn’t trying to escape, he just wanted a burrow it seams. I will probably take precautions for my bunny so he won’t burrow.
