Strength varies from creature to creature, with felines generally being the strongest and primates being the weakest (although exceptions like the Gorilla do exist). Strength can be increased if a creature carries and/or throws objects such as trees and rocks. Fighting other creatures in combat can also develop strength. The strenghten creature miracle increases this stat to 100% no matter how low it is, although it is only temporary. Lack of exercise, and constant sleeping can decrease a creature's strength, gradually reducing it back to 0%.
