Hey again!
Hope I don’t post too much on here.
So, Gus’ current setup (before his surgery, he is currently in a recovery pen) is in our kitchen. Our biggest issue was closing it off in a way that was still easily accessible for our cat and family. (Side note: our cat has never exhibited any predatory behavior towards him, if anything she very much cannot be bothered by him. I would never give her free access if I had even the slightest inclination she wanted to hurt/hunt him in anyway.) We came up with a door system:

While I am confident the kitchen is enough space for him, I have found out that he is very scared of the oven. He cowers in the corner whenever it is on, or if we even put a pan on the stovetop. He hates it. He also likes to be where my significant other and I are, and most of the time that is in the bedroom and ultimately, free roam is the goal.
So here is my issue: our bedroom is sort of a loft style where you go up a flight of stairs and the second level is the bedroom. The stairs are extremely narrow and he is too afraid to go down on his own, but has no problems going up (as a matter of fact whenever given access he much prefers being upstairs). Does anyone have experience with ideas on how to make a bunny feel safe going downstairs? We have considered a ramp on the side, but I am afraid it will be too steep. We have also considered making his own little bunny stairs, basically like a series of small shelf type things attached to the wall, but I think that could get pricy and without them being attached to a stud I’d be afraid of some sort of failure, even if he is only 4 pounds.
We tried to teach him how to do a zig-zag type thing down them, but he will only go down one if it is onto our arm and then the step itself. Any ideas or advice would be greatly appreciated! I’m trying to have some sort of setup for once he is healed from his neuter, that way he never has to be alone downstairs near the scary stove again!
