Actually, PTS's don't lay eggs, their babies are liveborn. A mother will usually have one offspring every 2 years, twins just occasionally. These are nocturnal animals and you won't see them much at all during the day.
Some PTS's calm down nicely, others wont'. I have an adult female here that is just evil at times. They have wicked sharp claws and clipping them is cruel since it really inhibits their climbing ability. Their bite is surprisingly strong and painful.
Most PTS people keep them in small colonies. Both parents look after the young, often for a year after birth.
Three years ago you could get imported gravid females for as little as $70. After importation was ceased the price quickly rose to $600. I see just recently the price is dropping again, probably because people have realized that, because of their slow reproductive rate, that they just aren't a profitable project. Interesting creatures just the same.
