Thanks for the welcome. As Tashi is settling in I'm working on become a better blind bunny parent. Fortunately, he is a very forgiving bunny!
At the moment, I'm using the NIC panels simply to expand his bounded space. He started out in an xpen, which was a big step up from the cage at the shelter. Although I want him to stay safe and secure it is clear he needs and wants more space. Enter NIC panels and zip ties, with the result a bigger pen. I am trying to imagine a way to build an 'upstairs' that is completely enclosed (except a ramp up), so that he can enjoy zipping up and down as well as around. If anyone has any suggestions, I'd be grateful.
His enlarged space is going to include a one-story mini-haven (so if he climbs on it there won't be far to fall), as well as a box with stuff to dig in. At the moment he is all about rearranging his fleece blankets, and throwing his basket around, so I thought something with more substance would make him happy. I have noticed, though, that he is inclined to eat the paper in his space rather than simply chew on it. How much can he eat before it becomes a problem? What would be safe to allow him to dig in?
Finally, looking a bit ahead, I was thinking about clicker training as a way to develop a better relationship as well as to communicate. I'm aware that there is a literature on this, but wondered if anyone had any experience they could share.
Thanks again for your advice, and for the links to info. He and I both appreciate it.
