A Courtesan of Rome Adoptable Animals

Greyhound
In Chapter 4, when you accompany your new patron, Senator Cornelius, on his hunt, Marc Antony joins you with his greyhound, Artemis. He tells you that he plans to sell her, but noticing your expression, he offers her to you instead. If you decide to purchase her (💎20), you can change her name. Antony teaches you the few commands she knows, such as Ito! which causes her to hunt. He says she is the best hound that he has bred to date, out of both of his best lines. She accompanies you in most chapters, such as Chapter 13 when you follow Legate Aquila.

Monkey
While riding with Cassius, a monkey pops into your litter. You have the option of having Cassius purchase the monkey for you (💎20). His default name is Cirta. His seller tells you that he can unlock most locks, and you use him to free Victus from his chains in Chapter 17. He also throws items at Xanthe when she tears apart your room searching for "evidence" of your "crimes".

Asp
In the Temple of Ceres, Iuna Pythia sets an asp loose in hopes it will kill Delphinia. However, the latter is not scared and can choose to keep the asp as her familiar (💎20). Its default name is Laret but is changeable. If Delphinia keeps it, the asp will settle around her neck and shoulders and warn her acolytes not to disturb her when she has visions. In Chapter 13, Delphinia has the option to let the asp kill Iuna Pythia.
