Sharing her experiences with raising emus, Alexandra Douglas found that emus make the best pets when they are young. Emus are very dangerous if you do not understand them, she says. Male birds are friendlier at least until breeding season. Emus are sociable creatures, they like water and do best with at least one other emu in their flock.
