Thought I'd post an update here a year and a half later!
Unfortunately I decided that I didn't have the space or money to keep Wallace and I ended up finding a wonderful new home for him with a family who had recently lost their spoiled pet bunny. I've received updates on him here and there - he's spoiled rotten! He's best friends with their small dogs, he roams free in their house, and he gets tons of fresh food from their garden. He definitely has a better life than I could have given him, especially now that I'm away at college most of the year.
Thanks for all of the kind words, everyone <3
