FLS- didn't your mom talk to your dad about this? Maybe a three way conversation with your mom, your dad and you- with calm heads, can talk again. What about if you made up a contract of the things you would do every single day- keep their work to a minimum...on a trial basis? Don't make it an yes/no decision right now. Maybe say you would like to try it for a two month time...give everyone a chance to adjust? Find out WHY he doesn't want the bunny in the house..find his REAL reasons...and see if you can't discuss them with him without yelling/fighting, etc. Try to speak to your mom privately, and see her thoughts. Don't give up. Not getting something on the first try doesn't mean it is a lost cause..you gotta stick in there, and keep trying...Good Luck.
