Pickles is a female cat owned by Francis. Her and Spitsy, a dog living in the same neighborhood owned by Donald Eustis, are engaged, despite the fact that they are different animals. Pickles is an outdoor cat, and she likes to lie down on random driveways.
It is unknown when Francis bought Pickles, but she quickly developed a habit of marking her territory. She also fell in love with Spitsy, though when and how they came together is unclear. Once, Nate got a black eye trying to stop Spitsy from reaching Pickles while they were on a walk together.
She is a very intelligent cat, once demonstrating just that by her EMT training. She can mountain bike and juggle on a unicycle while whistling. She can also play chess. Once Francis brought her to his basketball game so she could be their mascot, even giving her a miniature jersey and tiny pom poms, which Nate didn't like, leading to him deliberately throwing a basketball at her in the comic strips.
Pickles is shown to be an outdoor cat, always laying on the ground as if she owns the world., as quoted by Nate Wright.
