Hey, I have just found something in my pygmy terrarium!!! I received my digital thermometer today, so I went over and opened the doors, so I could position the sensor, and Kitty was in the plant, moving away from me, and there just below her, in the plant, was a white tic tac -- an egg!!!
Just one, for now, but laid in the plant, not in the substrate. Talk about strange. So I gently moved it down and dug a little bit of substrate away and put the egg there. I don't know if it will hatch, but I thought it was worth doing rather than leaving it out in the open up in the plant. How strange is that? Seems these little wee creatures are a bit unusual. I will be watching to see if she lays any more eggs, as the literature says about 5 eggs. Now I know how you feel Jose. I did want to get another female, but at this rate (if babies come), I will need another terrarium!!!
Too cool. That last article I posted says incubation can last from 135 to 170 days. I have read some folks insist to put them in an incubator and others insist not to touch them. Just leave them in the substrate and let it run its course. Thus far I'm thinking the latter. I really dont have the money to buy an incubator though you can get a really nice one fairly inexpensive. About $35 plus shipping. And then theres the question of wether or not they are fertilized. I still am guessing yes. She laid them about 2 inches behind the edge of the substrate heater directly under the large leaves of the pothos I put in there. Nice and humid and warm with leaf cover, just as the article said. Gonna be a long wait. 
. I say let nature take it's course , I'm sure your little beauty knew what she was doing when she laid them there. Just keep doing what your doing. Maybe put an extra temp sensor there? either way congrats. My mouth dropped when i read this! 
she is not a rat! she is a DOG
