A single breeding pair can produce about 500 mice in about 5 months under ideal conditions. In the wild, their average life span is only a few months. Baby field mice are blind, deaf and bald at birth but mature within about 3 weeks. Females are sexually mature at 4 to 6 weeks. Along with their natural habitat of the fields, they can be found in human habitation including homes and barns.
Fortunately, the Indians know that many fans enjoy entering the park several hours before first pitch, and are willing to accommodate. For a 7 p.m. game, for example, Progressive Field opens at 4:30 p.m., but be sure to line up at Gate C, as it's the only gate that opens this early.
1 All other gates will open 1 Â½ hours prior to the start of the game, allowing fans access to the entire ballpark.  On bobblehead giveaway days the Center Field, Left Field & Right Field Gates will open 2 Â½ hours prior to the start of the game, allowing fans to access the Center Field stands and concourse area.
