Arrendajo ("Jay," as Moongaze calls him) is a sabertooth cat and an artist living near the rebuilt Griffith Park Observatory, New Los Angeles. His markings are a combination of an ocelot and a puma, as illustrated in paintings by Mauricio Anton and Mark Hallett. Jay is Moongaze's old flame. They met while she was starting out her career in New Los Angeles as a researcher. At one point they worked together, and he created beautiful illustrations to accompany her research. Jay is "the one that got away," and he tries very hard to get back into Moongaze's life as she is trying to move on.
