i kept mich when i had a monitor, and it sucked. i cleaned the cage top to bottom every week, changed 100% of the bedding every week, and they still stunk.
all you need to care for them is a 10 gallon tank, screen top, water bottle, substrate, mouse food, and mine reallt liked a cardboard box to do as they pleased with. i have no clue how long they live for tho, i only had my breeding setup for about 4-5 months.
