Rum are there humans in your universe or were other animals hunting them for sport?

all animals, so cheetahs were hunted/killed by whatever animals ruled Rome; tragic but true

Id assume it would be Wolves maybe?

They're like a major symbol of the roman empire. maybe dogs along the same line "Canes Pugnaces" and "molossus" were fighting dogs (mastiff and Rottweiler type dogs), greyhounds are Italian for sure.

Though it could also be like farm type animals like horses, goats, and i think pigs? I know there were wild boar im unsure if they were able to tame them.
