Sheldon: Leonard, do you really think you can satisfy your need for a relationship with a genetically altered cat?
Leonard: Maybe, if it's a cute little cuddly cat.
You've just had a bad experience: losing your job, your house, The End of the World as We Know It is upon us, or you've run out of chocolate ice cream. Whatever it is you've lost, it was very dear to you, and you want nothing more than to be relieved of this bad feeling. Unfortunately, no human will help you.
No human will help you.
That leaves plenty of room open for a furry friend usually a cat or dog, but any other furry animal with a penchant for sociability can also suit the bill to find you in your hour of need and offer a sympathetic body for you to channel your sorrow into. It works like this: you stroke the animal's fur, it responds with pleasure, and you feel better. You feel better because you have made your pet happy, and this success, however small, renews your own sense of self-worth and will to pull yourself back up from defeat.
The Aloner may want a pet specifically to make him or her happier because other humans just don't understand them. The Team Pet may also be the only person able to pull The Hero out of his/her funk if the task exceeds the capabilities of anyone else. Anyone who attempts to interrupt Fuzz Therapy engages in a simply egregious act of kicking the dog.
- In Catch Your Breath, Kakashi uses his summoned dogs as therapy animals, deploying them for his sake and for the sanity of his teammates during tough times.
- Actively invoked by Izuku in Yesterday Upon The Stair with his rescue cat Mika. Whenever Izuku notices one of his friends is having a rough time, he'll drop Mika on their lap and leave them alone with her for a while. Kirishima calls it a rite of passage in a side story due to how many people he's done it for.
- Izuku does this for himself in Live a Hero. After coming across a box of six abandoned cats, he couldn't bear to leave them alone, causing him to take them all home despite his mother's worries about the costs of feeding and caring for them. She ultimately relents after seeing how happy and relaxed they make him compared to his normal mental state, in which he struggles to avoid stabbing Bakugou after the latter bumped into him on the street. They also calm him down after his overuse of his Quirk renders him temporarily deaf and blind, as their warm, fuzzy fur allowed him to recognize them instantly. It's heavily implied that he's attached to cats because his sister would call him "Kitten" to absolve him of his guilt for being forced to use her for target practice when throwing knives.
- Invoked in Extra Life. To help Chiaki overcome her depression, Izuru gets her a rabbit, specifically mentioning that pets are helpful for therapy because of this trope. Taking care of Yumigami, as she names her, petting her when anxious, and cuddling her when having flashbacks all prove very beneficial for Chiaki.
- My Dog Skip is all about the beneficial effects of the eponymous dog on Willie's life.
- She may be feathered, but Harry Potters owl Hedwig does function as his only friend during his annual weeks of summer torture with the Dursleys. It saddens him greatly when the Death Eaters kill her during his permanent farewell to Privet Drive.
- Tomcat Blue Eyes Diaries: Blue Eyes and his owner often cuddle. Blue Eyes likes to be petted or brushed, and enjoys purring into his human ears. In one chapter, Cat Up a Tree incident led to Blue Eyes' human getting injured very badly and being taken to hospital. Blue Eyes was left alone, crying sadly the whole time. At the end of the chapter, the human is brought back home and Blue Eyes cuddles with him in his bed. Therapeutic for both of them!
- Animorphs: In her first book, Rachel morphs into her friend Melissa's cat to spy on her house (she's the daughter of the school's assistant principal and local leader of the Sharing, the Yeerk recruitment front). When Rachel sees Melissa crying over her parents ignoring her (although Yeerks are able to perfectly judge what their host would say/do in any situation, they only bother to do so when necessary), she goes up to comfort her.
- Inverted in Discworld, where a form of torture involves locking a prisoner in a spikeless iron maiden with several kittens. If the torturer drops by and doesn't hear contented purring, he gives the box a few good whacks.
- Rachel Lindt of Worm starts trying this trope with her dogs after her Character Development, loaning them out to various villains and heroes in need of comfort but who cannot or are unwilling to talk to a person about it. She also hands out puppies to orphan children.
- From The Big Bang Theory:
- In early season one episode "The Fuzzy Boots Corollary", Leonard pines after Penny, his attractive newly-moved-in neighbour, and he sees her kissing another guy which gets him depressed. He tries to date someone else, but it doesn't work out. He starts listening to sad emo music and wants to get a cat. He gets a scratching post and starts thinking about names. He doesn't get the cat in the end as he invited Penny for a date (though she doesn't realize it was a romantic gesture).
- When Sheldon breaks up with Amy for an episode, he gets about a half dozen cats, whom he plays with affectionately. He denies that he's compensating for the loss of Amy's companionship. When they get back together, he "sells" the cats (actually gives money to people to take them).
- Related in thought: whenever Sheldon feels sick or depressed, he asks Penny to come over and sing a song called "Soft Kitty" to him. It was a song that his mom sang to him when he was sick as a kid.

- In an Imagine Spot on Scrubs, a doctor cures a terminally ill patient by dumping a box of kittens on him.
- Calvin and Hobbes named this trope. After having what he describes as a "rotten day," Calvin comes upon a sleeping Hobbes, gets the inspiration to rub his belly, and sparks what seems to be a wonderful dream in the tiger. The last panel of the strip sees Calvin walking away, a smile on his face, declaring that "fuzz therapy" has cured his mood. Hobbes' expression makes it clear that he appreciates such moments too.
- This comes up in Peanuts occasionally, with Snoopy being the fuzz and usually Charlie Brown or Linus as the person needing the therapy. "Happiness is a warm puppy."
- The sequel to Ace Attorney Investigations: Miles Edgeworth has a prison that gives each prisoner a pet if they don't already have one. They even let infamous blind assassin Sirhan Dogen, keep his seeing-eye dog Anubis, even though Anubis was known for helping Dogen in his "work".
- In one Breaking Cat News strip, two of Georgia's cats provide Fuzz Therapy while she's lying on the couch feeling ill.
- Stand Still, Stay Silent: After his non-immune cousin gets wounded by a Plague Zombie, Lalli withdraws from the rest of the crew to come to terms with what just happened. The Team Pet kitten, with which Lalli has a one-sided Sitcom Arch-Nemesis relationship, eventually joins his side to escape the shouting of two other members of the crew, and he ends up picking her up and hugging her in an O.O.C. Is Serious Business moment. The next thing Lalli is seen doing a very short amount of time later is slapping a bunch of papers on Reynir's lap and asking him to come up with a variant of his first working rune that does not catch fire when it activates.
- Many hospitals (and some nursing homes) have animal therapy, where a small dog or cat (more rarely, other animals such as rabbits will be employed in this role for folks who are afraid of or allergic to cats and dogs) is brought to a ward with a handler and visits the patients' rooms, where the patients can pet and visit with it and generally feel comforted in their illness.
- Some colleges and universities also bring in therapy dogs at exam time to help ease students' stress. This can be particularly enjoyable for students living in dormitories, who generally aren't allowed to keep pets.
- There is scientifically-backed evidence touting numerous health benefits to owning and petting a fuzzy animal.
- Cats have also been used by prisons to help in the rehabilitation of criminals.
- Crazy Cat Lady:
- It happens in RL that a lonely (often older, unmarried or widowed) woman comforting herself with a bunch of cats.
- Inversely, it can be a specific manifestation various mental illnesses, such as OCD, addiction, dementia, etc. This makes it more of Fuzz Symptom rather than Fuzz Therapy.
