I think the bottom line is this: as long as people continue purchasing from the big box stores the big box stores will continue filling their stores with poorly treated, underfed animals.
There are enough reputable breeders to support the market. Purchasing from these reputable breeders and avoiding the big box stores and the unethical breeders may help to reduce the poorly treated animals in an over saturated market.
We live in a world where you can search the internet for local breeders as well as purchase animals to be safely, humanely shipped to your front door.
Doesn't purchasing from a reputable breeder just make more sense????
