Jiji
In the movie Kiki's Delivery Service, Jiji is Kiki's friend. Kiki is accompanied by Jiji while she completes her witchcraft training. He once had to pose as a stuffed cat to deliver a gift for a boy's birthday. He was the identical replica of the real stuffed cat that had gotten away in the woods. Black cat Jiji has big, white eyes with black pupils. His ears have iris purple inside. He lives a considerably longer life than a typical cat because he is a witch.
He can talk and ramp up the sass, but it seems that only Kiki can hear him. Whose cat gives other cats the side look and sneers at them? Even though he is frequently snarky and even comes off as almost conceited, he is still Kiki's guardian and will go to great lengths to protect her. Only the most devoted pet would act like a toy cat after his owner misplaces the real one that was a gift for the boy she is crushing on.
Jiji was supposed to represent Kiki's childishness, according to Miyazaki, therefore it's possible that Kiki projected these ideas onto Jiji during her voyage in order to hear what she needed to hear.
