I have personal experience with this. Patches was an "Easter bunny".
I'm sure she was little when she was purchased from a pet store right before Easter. Several months later, when the novelty wore off for the people who purchased her, she weighed about 5 lbs. (When I responded to their ad, they said "she got big"). DUH. They had her in a hamster cage and she could barely turn around! Now she weighs in at 10 lbs. I bet the pet store sold her as a mini-lop, too, which she clearly isn't.
My message this Easter: If you really want a bunny, adopt one from a rescue and love them their whole lives!
Happy Easter every bunny!
