House Rabbit Soc. has an open letter to the head of PETCO pulling their support because they are selling rabbits after saying they would not.
I printed off a copy but you should check the HRS website.
Breeders are mainly to blame. They want the dollars cute babies bring in and bunnies grow so fast they take them way too early from mom. Breeders are also usually breeding to get a certain coloration and so they are all these "throwaway" babies that don't make the grade for rabbit shows. It is a terrible situation.

Also when babies are taken too soon from mom, they still don't know that they are bunnies and how to act like a bunny.....if the baby in turn has babies and didn't get the care she needed from her mom, she can't in turn properly take care of her babies. We've seen this happen at the sanctuary and it is so sad. So there are 2 villians in this scenario.
By buying a bunny from a pet store the breeders and stores are encouraged to continue this terrible practice.

My PETCO has had bunnies in the past but do not now. I don't know if the manager has changed his mind or they're just out of babies right now. A PETCO manager in Mtero Detroit told us he won't sell bunnies because they are just too delicate and people don't listen to the care instructions. I don't know but I think he is the exception for PETCO and not the rule.
