Cali is Katie's pet cat. She may look cute, but she can cause a lot of trouble.
She is also shown to have a very big appetite in "Pups Save a Train", where she tries to steal a Seagull's findings, which is not a good idea. Like most cats she loves to eat fish and was the only one who liked Cap'n Turbot's Fish Cake made with real fish scale icing in Pups Take the Cake.
In Pups Save Alex's Mini-Patrol, she becomes a member of Alex Porter's Mini-Patrol along with Chickaletta, Little Hootie, a Bunny, and a Turtle.
Cali may look sweet, but she's actually very sneaky. When she gets surprised or scared, she hisses and meows. Cali is somewhat spoiled and has a love of eating, to the point she will even eat Pup food and treats. Though she is occasionally antagonistic with the Pups and Chickaletta. Like most cats (and Rocky) she is shown to have an aversion to water, getting wet, and taking bath in a bathtub. However despite the fact she shares this fear of water with Rocky, she has no problem seeing him get wet or forced to take a bath in Pups Make a Splash when she kept thwarting Rocky's attempts to hide and avoid taking a bath, to the point she tried forcing him into the tub only to end up falling in herself. However despite her fear, she has a bad habit of lying on top of things like towels or other high structures near the bathtubs, which often causes her to fall in by accident. Cali also appears to enjoy stalking (and possibly hunting) the local seagulls. She can also shown to be jealous when Katie dotes on younger kittens like Precious. She has a friendly rivalry with Chickaletta. Though she can be somewhat antagonistic towards the Pups at times, she is for the most part friendly to them and is always grateful to them whenever they save her.
Cali has grey and white fur (with a hint of light lavender) She also has navy blue eyes that match her fur. She wears a purple collar with a little golden bell.
