There is not an overpopulation of guinea pigs as bad as dogs and cats. I have researched breeding piggs, and I will keep all the babies. So why should people get mad at me for that? Why are people so fed up on this issue?? I am not trying to brak the rules or anything, but I am not going to be some backyard breeder anf I will take good care of the pigs and will keep them or give them to responsible friends. So whats the big deal??
