They are about a year old. Really great and way to smart for their own good.
The one you see in the picture is the smaller one called Lucifer, (because of his evil looking goatee) he is about 3 inches now. The bigger one called Wife Beater, (he grew in to his name He looks like he has a five a clock shadow. ) is a bit over 4 inches and likes to use his size. I got got them at the same time and they were the same size.
