The adoption agency will hopefully help drive home just how much responsibility having a rabbit will be and your mother will ultimately be responsible for it.

There is only so much you can do about it if your mother is supporting your sister. Hopefully your sister has learned from her past experiences and will take better care of the rabbit.
My sister is immature for her age. From what I've seen she doesn't have much responsibility and is not very good at researching and planning ahead.

The unfortunate thing is that to my knowledge, she hasn't learned from her past experiences. It's ongoing as I just recently cleaned her rancid fish tank (there was slime and sludge all over the place, the fish were all moping at the bottom).
