Before the laughter starts, let me say that I have been an amateur Herpetologist for many years (over 30) and in addition to owning many reptiles, I actually owned a Reptile store in Chicago. I have had many pythons and boa constrictors so I know that generally, pythons lay eggs and boas have "live birth". I have two boa constrictors that I received from a "kill" shelter. They call me when reptiles are seized by the local or state police. One had stopped eating for a couple of months. Since the body mass was good and I could not detect any other problems (except mites which is a continued problem) I did not worry much. Two days ago I found 7 masses in the cage which were about 3 inches long and about 1.5 inches around. They look like brown eggs. They are firm an have the feel of plastic but definitely came out of the boa. I have no idea what these are. Can anyone help me determine what they are?
