Unlike the other species, the Black-Tailed does not hibernate, probably because it is usually found in warmer and wetter climates than the others, and its staple diet of grasses is therefore available all year round. In the autumn, broadleaf plants become more important as green grass is less available. In winter, any available green vegetation is consumed. In the spring and summer, each prairie dog consumes up to two pounds of vegetation per week.

Phasmids (variously called stick insects or walking sticks) are a very widespread group, occurring on all continents and in most climates. There are no native British species, but at least three New Zealand species have been established in the UK for nearly 100 years. In warmer climates they are a potential pest, so in the US especially keepers may face restrictions on whether they can keep them, depending on the local climate and agriculture. Despite their potential for producing large numbers of offspring, in the UK at least they are an apparently harmless addition to the British insect fauna.
