This is Dasher. He joined our family on December 25th, 1999 at the age of 5 months. He was named for his ability to chase down crickets, and I guess the Christmas part had something to do with it. The life expectancy of a leopard gecko is about eight years. That's about another 376 trips to the pet store for crickets at a total cost of $1,692.00, provided of course that crickets do not go up in price.
