I can understand why people selling their own pets and breeders who breed rodents specifically to be sold as pets would be concerned about their animals being fed to reptiles. Though, I'm actually surprised franchise companies even care. They're typically more concerned about money than what happens to their animals. I would understand if an employee were to become attached to one of the animals, it would be upsetting to know that it was being used to produce feeders. But, at a corporate level, what reason do they have to dictate what we buyers use the rodents for? Does it make it animal abuse simply because they were not labeled "feeders"?
The corporate levels of PetCo and PetSmart need to enforce better feeding and care of their reptiles before they enforce buyer's policies on rodents. It's them who create the rules of how much the employees are permitted to feed the animals.
