haha you two!

I vote for the bunny having a home with you. Is he a wild bunny or was he possibly from someones pets? you may want to be careful when around the children if its a wild bunny as it could be more likely to bite.

Sounds like hes doing really well though. and dont worry, rabbits dont live even close to 20 years lol. Your looking at 8 or so at the very most. Even thats a stretch for a rabbit. but it will be long enough to bring your kids into teenhood lol.
