Dr. Crane's assistant. Standing at 190cm, he can seem rather intimidating. But in truth, he's very calm and kind, as well as skilled with his hands. A bit of an airhead, though. He has no memory of his life before the clinic. He was taken in by Dr. Crane (who was the one that bestowed the name "Jack... read more

Dr. Crane's assistant. Standing at 190cm, he can seem rather intimidating. But in truth, he's very calm and kind, as well as skilled with his hands. A bit of an airhead, though. He has no memory of his life before the clinic. He was taken in by Dr. Crane (who was the one that bestowed the name "Jack" to him), and has chosen to work for her to repay her kindness.

♀ f

Head doctor of the clinic. Human. Overworks the protagonist with no mercy, and is curt with the patients, but reliable nonetheless. Despite her cool countenance, she's far from perfect. When she gets upset, she's kind of cute?

A patient of the clinic. A Siamese cat. Her condition causes emotional instability, her moods going up and down quickly, like she has two different personalities? Though she's usually a confident (if manic) type of person, she can quickly become paranoid and depressed, refusing to interact with anyone. Self-conscious about going into heat. Will refuse treatment until she's almost driven mad by her condition.

♀ f

One of the twin sisters who are patients at the clinic. The two of them are nearly identical, except for the color of their tails. (Nami's is brown with a white tip.) It's not just their looks, the twins' personalities are identical as well, and they often speak in synch or finish each other's sente... read more

One of the twin sisters who are patients at the clinic. The two of them are nearly identical, except for the color of their tails. (Nami's is brown with a white tip.) It's not just their looks, the twins' personalities are identical as well, and they often speak in synch or finish each other's sentences. Maybe they're telepathic? The twins are innocent, energetic, and mischievous Calico kittens. The two of them are the clinic's "mascots". Their condition is an accelerated heart rate. Though unaware of their heat cycle, they do illicit things with each other. This doesn't improve their condition, however.

♀ f

The oldest patient in the clinic. A perpetually-sleepy Persian cat who lives life slowly. She enjoys reading, and may be unexpectedly intelligent? Her condition is an excessive libido. She's not only aware of going into heat, she enjoys it. Once this "switch" in her is activated, she goes from caref... read more

The oldest patient in the clinic. A perpetually-sleepy Persian cat who lives life slowly. She enjoys reading, and may be unexpectedly intelligent? Her condition is an excessive libido. She's not only aware of going into heat, she enjoys it. Once this "switch" in her is activated, she goes from carefree to sexy in an instant.
