I think 100:1 ratio for "long and happy life" among lab mice would be hilariously optimistic. Because of their speed of reproduction, their lack of reusability, and the fact that in order to cure diseases you first have to inflict them, lab mice are basically in a constant state of massacre. They're not even livestock. They're more on the tier of stationery.
