Some pets are endearing because they’re so otherworldly. Tortoises, with their ET-like appearance, are a good example.

Tortoises are relatively easy to manage, but they’re not for everyone. They can live decades and do best outside with sunshine and space to roam. A temperature range of 70 to 90 degrees suits most species, with shelter added for cooling or warmth.

Other needs vary, depending on the species. Desert tortoises thrive in dry environments while tropical species require more humidity. Diets differ among species too. In general, tortoises like brightly colored fresh vegetables and fruits, but some species need more protein while others do best with less fruit.

If you want a tortoise, first educate yourself on various species and their needs. That includes finding a tortoise-savvy veterinarian who can provide advice.
