The heart of the show. Katie zooms around in her wheelchair with her arms wide open, ready to catch whatever cat is flying at her at any given moment. She understands the cats in ways other people can't — or won't. She's patient and fearless and the first one to notice when something is wrong. She always has been. The show never explained how she ended up with so many cats. Katie probably knows. Katie always knows.

Bright, energetic, first through every door. Flare is the loudest welcome and the first signal that something is happening. She's warm orange and has the kind of purr that shakes the windowsills. She might be Vinnie's sister. Nobody has asked Flare directly.

The nocturnal one. Vinnie's battle cry — HAHHH-ROWWWW!! — has been described as "the sound of someone discovering bad news at 2am." He loves the night, he loves Katie, and he mostly tolerates everyone else. He might be Flare's brother. He is definitely Mr. Tufts' father. (Vinnie has confirmed nothing.)

The patriarch. Boscar has been in the house the longest and he knows it. He blinks at you very slowly, like he's delivering a verdict. He naps by the front door. Nobody moves Boscar. Not even Mama TrudyBooty. Especially not Mama TrudyBooty.

Poncho shows up and then Poncho leaves. He always comes back eventually. His episodes are the most mysterious ones. Where he goes between appearances is never addressed. Katie doesn't ask. She's just glad when he's home.

The newest arrival. CutiePi showed up in Season 3 and was immediately warmth and sweetness in a season that badly needed it. We love her. She is good and pure. She does not deserve what came after. 💕

He's not a main cat but when he shows up the whole house knows it. RRABBA-BODDY-HEERRRRR!! That's really all you need to know.

He doesn't live there. He acts like he does. He knows his way around better than cats who have been there for years. He arrives without announcement. He leaves the same way. He is probably Vinnie's son. He has never confirmed this.

Katie's mother. She did not sign up for any of this. She would like significantly fewer cats. She is not getting fewer cats. She loves Katie with everything she has, which is why she has not moved them all out. She is screaming internally at all times. We respect her.
