Having a baby would be like having a litter.
Buying a dog from a pet shop, is like adopting a baby from an orphanage.
If u try to adopt a baby, i believe the "potential customer" is then put through their paces to be classed as a suitable parent.
Pet shops should be the same. If they had the exact same criteria as an orphanage, then maybe, Just maybe, i could turn a blind eye... Unfortunately that will never happen.
Nevertheless, pet shops and anyone who fuels their business are a bunch of douchebags.
