I had a local petstore to buy supplies from. they didn't have live animals for sale until now. I went in Sunday to pick up bedding and there were two rabbits and two guinea pigs. I asked about the guinea pigs and was told by the owner that they were a male and a female. I asked about pregnancy but he told me that they were too young to reproduce at seven weeks of age. I suggested that they could in fact, reproduce at a younger age than that but he said no, couldn't happen. Grrrrrrrrrrrr.
Time to find a new place to buy my dog food and bedding. Do I need to tell you that these piggies were shipped in, were being housed in an aquarium with no shelter and only pellets to eat? I wanted to get the female out of there in hopes that she was not yet pregnant by her brother, but I knew that if I bought her, the owner would think "Wow, these things are selling like hotcakes! Better order more!" :sad:
Maybe you could ask your vet if they could maybe tell the store that they breed at earlier age or something. Is the store a chain store? If not, you may be able to persuade them to do stuff differently
