A series on Animal Planet featuring Jackson Galaxy, "musician by night, cat behaviorist by day," taking on cases from clients whose pets are out of control. Each episode features two cases, and follows Jackson as he meets the clients and their cats, inspects the animals' accommodations, observes and assesses the cats' behavior, and instructs the family on how to address their pets' issues. Jackson prefers a holistic approach to his treatments, and typically suggests activities such as restructuring of the cats' physical environments; adjusting the animals' daily schedules to fit the "hunt-feed-sleep" routine observed by cats in the wild; meeting the cats' requirements for physical and mental stimulation; and educating owners on how to interact with their pets in a healthy manner.
Blue and Orange Morality: Jackson often ends up pointing out that frustrated humans try to apply their own senses of morality onto cats, who really don't have such concepts in the first place, so most of the time it's just the humans protecting their own issues. One such owner was convinced that her cat was deliberately peeing outside his litter box and called him a "spiteful urinator." Jackson's reaction says it all. Turns out the cat was doing it because he was declawed (something that Jackson and most cat experts will agree is a cruel thing to do in the first place) and the litter they were using hurt his feet so much that he didn't feel comfortable going in the litter box, and as soon as they switched to another litter that didn't hurt him it stopped.
Cats Are Magic - played with in the case of Pump, an elderly orange tom whom Jackson suggested was drawn to the healing properties of the room where his owner practiced her energy medicine.
Cats Are Mean: Played straight in the series title (and taken Up to Eleven with the new logo, in which the snarling black cat is given devil horns and a forked tail while flames swirl behind it), but Jackson makes it clear that the cats' behavior is due to health issues, psychological imbalances, or problems with their living environment, not spite or malice. And the trope is fully averted by the end of each segment, with Jackson helping cats and humans to understand each other and live peaceably.
Cool Shades: Jackson often sports these, and occasionally uses them as part of his evaluation session with the cats, placing them on the floor near them to let them get his scent. A few clients have these as well.
He's also appears on a couple of other Animal Planet series, such as America's Cutest Cat and Cats 101.
Cute but Cacophonic: Noise complaints are a big reason people end up calling Jackson, such as in the case of one Sphinx cat with an amazingly loud and grating meow.
Domestic Abuser: In the episode Macho Cat, Buddy mirrors his owner's dominating and bullying nature to such a point, you can't help but see Derek as a Domestic Abuser to both his girlfriend and her cat. It gets so bad that Ryann, the girlfriend, moved out with her cat.
Fluffy the Terrible: Applies, at least in the beginning. Most of the cats have normal names like Larry. Special mention goes to one that was actually named Mr. Fluff.
Gentle Giant: Jackson himself. He's over six feet tall and built like a brick wall.
Kindhearted Cat Lover: Jackson, of course, and many of the cats' owners qualify as well. Special mention goes to In-Hae, who went to great lengths to get along with her fiance's cat Marco, with heartwarming results.
Manly Tears: You will know when Jackson is especially moved by one of his clients.
Mercy Kill: The mother of one client was convinced that her daughter's cat, who was blind, had such a reduced quality of life that this was the best option. The daughter was understandably pissed off by this, especially when Jackson found out that the cat was only mostly blind and they were able to increase her quality of life dramatically thanks to his help, and at the end of the episode mother admitted her mistake and was able to reconcile with her daughter.
Nonindicative Name: A variant on the show's name. While some cats who exhibit some violent behaviors qualify as cats from hell, some of them who are merely annoying don't fit the bill.
Above example: Pump, an orange elderly cat who lives with a "vibrational therapist". Sure, he walks around and wants to go near the therapy table, but the cat isn't doing any harm. Most of the episode consists of Jackson trying to convince the owner of this.
There was once an 18 year old cat who was constantly meowing at night. It turned out that thyroid problems prompted the cat's obnoxious yowling.
In several episodes (especially the "Vibrational Therapist" one) Jackson full-on states that the cat is not the problem, the owners are.
Stock Sound Effects: video footage is often "enhanced" with generic crashes, bangs and cat screeches.
Theme Naming: Pepper and Olive; Chompy and Bitten (ironically, in the latter case, Bitten was the aggressor who used Chompy as his Chew Toy).
Bear and Monkey
Too Dumb to Live: Applies to more than one owner who insists on roughhousing with their cat when it's sending clear signals it doesn't want to be touched. Also, Khrys, who claims to be the owner of her cat Kitty, but leaves it to her boyfriend to clean the cat's litterbox and chase Kitty down when he escapes out the front door, because "That's men's work!"
Also one client with a cat who bit and scratched her who was pregnant and had been explicitly told by her doctor that they could not give her antibiotics, so her job was to make sure she didn't get bit. As they're talking to Jackson she reaches over to pet the cat, something Jackson had just told her not to do, and guess what happens.
