Rabbit-proofing a home is too difficult for me. I tried it and failed, ended up having a large portion of our basement (200 sq feet?) converted into his roaming area.

I'll likely never have a rabbit again, they require so much more effort to keep happy than any other mammals I've ever had. They are darn cute though. I vote guinea pig, they aren't anywhere near as much effort, easier to socialize, and plenty cute.
