They are ignorant towards the sex of their pets that do not have a visible penis or vagina. I asked for 2 female guinea pigs and was promised the tank only had females in it. I should have checked on my own (bad on my part), but months later I had 7. The she was a he and the other she was now knocked up. With the parenting guinea pigs being only 4 months the mother died shortly after birthing. So I'm stuck nursing 3 guinea pigs b/c the mother died of an internal infection due to early birthing, and the babies that needed the most caring died as well. Now Im caring for a father that I was promised was a female as well. I would not trade my pets for the world if I had the money to continue on and a space larger an APARTMENT SIZE living area. Plus I had to nurse the guinea pigs when I bought them b/c they were ill and mentally damaged. They abuse their guinea pigs. They are not well kept and should not have all of them confined in such a small space.
