Pets (Culture)

Kadi had a dog called Wolf.
Hank had a dog called Biggie
Zeth had a dog called Patches, who was littermate to Biggie.  They were trained to protect sheep.
Cats are kept, especially around Genfarms where Gens grow their own food -- which must be stored -- which attracts rats.
Likewise, cats are all over the towns and cities, because there are rats.  People harbor cats for all the reasons we do.
Out-Territory, every sort of animal Ancients kept as pets will turn up wherever there is the capacity to support them, or the need for the working-partnership with animals (such as horses).  At the shores, cultures make pets out of dolphins and other aquatics. 
In the space age, these animals will go with humanity to the stars.
