I went in to the pet store where I live to buy some litter box bedding and they had about 11 piggies for sale. One box was 2ft by 18 inches with 6 pigs in it and the other box was the same size with 5 pigs in it. I picked up a few of them in each box and sexed them. Much to my horror, there were boys and girls in both boxes. I asked the young girl working in the store if they knew that they had both sexes mixed together. She said that they had to do it that way because one of the males had been fighting with another male and they had to separate them so there was no way they could keep the males separate from the girls. She also said they were on sale for $5 each because they had to many and had to get rid of them! So they have too many but will allow the ones they have to breed thus making even more poor little piggers! I walked out of the store without buying anything.
