If people can't just dump their babies at a petstore they are going to take ALOT more precautions against breeding. If someone thinks we can just bring the babies back to the petstore if our 2 new guinea pigs end up being male and female then they aren't going to care if they have babies. They get to see cute babies and they can get rid of them when they aren't so cute. If a petstore doesn't take those babies though then people are going to want a gurantee these guinea pigs are the same sex or they are going to be more likely to seperate them so they don't have to keep finding homes for the babies. The same with the breeders. If they can't sell their guinea pigs they aren't going to want the headache of dealing with that many babies. If there is no demand then noone wants to supply more and deal with a surplus.
