Hannah is smarter than me. 
Yesterday while we were cleaning upstairs she got past the bunny proofing and behind the tv. My husband got her out, but we couldn’t figure out how she got back there. She hasn’t jumped any of the NIC fences yet and I’m making sure she doesn’t learn that she *can* jump them, so I hoped that wasn’t how she did it.
This morning I got to find out. There’s an NIC fence next to the tv that joins up with the stand. I thougth she maybe pushed it aside and snuck back. No. Instead, she got under the tv stand (pretty narrow) and army crawled through so that she came out behind the NIC fence. Needless to say, I now have NIC grids totally covering the front of the tv.
She also figured out how to get next to the couches where there are a lot of computer wires. She couldn’t push past the NIC grid, so she grabbed it and pulled it back until the gap was large enough. Apparently Otto was the first one through the gap
So I think we figured out a way to set up the grids so that she can’t pull them back. Backing up really isn’t a natural movement for bunnies, so I think it’s fairly impressive.
Every day she comes up with a new extremely clever way to get past bunny proofing. It’s not just jumping over fences or pushing through gaps. I think she’s planning a takeover!
