MonkeyBun, I really liked the idea you proposed about getting a bigger box to put under the litter box. Just have not found one that fits yet since you first suggested it. Of the numerous cardboard boxes stashed away in my house, none fit. But I am going to my favorite store (Costco!) today and they have boxes galore there. So my goal is to find one that fits.
That is where I get my boxes for her “phone book box”. She loves to shred phone books. And we have plenty for her to destroy. But I put the phone book into the box to keep it from getting EVERYWHERE. The part that got me was that she pulled the book from the box, and flung it all over the place. A while back I bought sheets of plexiglass that I put on two sides of her cage to protect my walls and adjacent couch from her litter flinging. So I am doing my best to adapt to her. She just keeps finding new ways to make it difficult for me. I love the idea of the NIC grid condos, but part of me is reluctant to try because I could see her tearing that apart in no time.
A friend may help, and I would love to get another bunny. But right now we just do not have the time or money for another animal. We already have 5 cats, a dog, Momo, and my reptiles. Not to mention we are thinking on having kids in the next year or two, so things are just going to get more hectic.
