Yeah, you and Bunny have a great relationship.
I've heard this story before about bunny moms killing and maiming their babies. What I was told is that the mom was most likely taken away from HER mom when she was way too young and so she did not learn from her mom how to be a bunny....everything she does is on instinct (or something)....

Oddly enough one of our rescued buns at the sanctuary had her ears and tail bitten off by her mom. She's a nice bunny, a little shy and she looks really weird but she is a very healthy gal otherwise. Her name is Precious.
