Arcane Creature

Arcane Creatures are magical talking animals with human level intellect and the ability to do spells of their own. Most if not all Arcane Creatures are adopted as pets by sorcerers and occasionally trusted non-Bloods. The exact origin of Arcane creatures is unknown compared to the sorcerers' origins in association with the Watchers, but it can be assumed there is a degree of relations or crossover.
Like Sorcerers Arcane creatures seem to possess their own bloodlines and Mana Marks indicative of their power but it has not been confirmed if this is passed through lineage in the same manner of Sorcerers or if Arcane creatures gain power through other means. Its possible all arcane animals inherit their abilities through their ancestry and can procreate with normal animals, but this is never specified. While it's been seen in the form of Xavier, an Arcane Cat, being attracted to and presumably matting with a normal cat (Mrs. Jingles) it remains unconfirmed if any offspring they produced (or could produce) would also be Arcane Cats. Arcane creatures also seem to have longer life spans than their Nonblood versions as Kira, an Arcane Ferret, once stated she knew her owner Ayden for at least 7 years while most Ferrets only live around 4-6 years and Kira still seemed to have a younger demeanor and persona. 
Known arcane animals:
* Dogs
* Cats
* Ferrets
Arcane creatures like Cats, Dogs, and Ferrets, are commonplace pets for Sorcerers and while some tend to be a bit condescending or annoying at times they serve as very loyal pets and companions to their sorcerer owners. Not all sorcerers have Arcane pets as owning them is more a preference but those that do will usually employ their own magic combined with their pet to help them perform certain high-powered spells on occasion. Some sorcerers such as Ashley have a degree of conflict with their Arcane pet as she and Xavier tend to bump heads and annoy each other a bit too much yet still care for each other as master and pet. Other sorcerers like the Arringtons don't want pets out of personal preference which lead Isabelle to adopting an enchanted cell phone robot she made and named I-Gurr as her pet though she was not technically an Arcane Creature. Sorcerers can also own regular animals as pets instead of Arcane creatures such as Claire Dupont and her dog Raven. Though Raven died and was revived by Alistair using necromancy she was not an Arcane Animal either before or after this. 
While it is never specified if there are legal hoops to jump through there have been cases of non-Bloods being given Arcane creatures as pets so long as both master and pet know to keep the secret, such as in the form of Oliver Thompson being given Anya as a pet by the sorcerer Lorraine Rose. The pair have become close companions, but Anya knows only to talk around Oliver and his trusted girlfriend Brooke with the rest of their friends and family simply seeing Anya as a very well-trained dog. It is possible that certain Arcane animals are in hiding among non-blood society similar to sorcerer kind but as the exact legal right of Arcane Animals compared to sorcerers has never been specified it is unknown how this would be viewed. However as Arcane animals have been shown to still live in shelters or pounds similar to normal pet animals it can be assumes a similar yet modified form of Animal rights exist among the Sorcerer society.
