Cockatiels. Affectionable and playful, easier to raise than other kinds of parrots, and they have a natural talent for whistling tunes. Not to mention many colors have bright red cheeks resembling Pikachu.
Pomeranians. My God, the puppies. Ever wanted a pet teddy bear?◊ ◊ ◊
Small greek domestic dogs! I mean, how can you refuse this cute look◊?! (Granted, most puppies fall into this)
Albino Pekingese◊ look like what you'd get if you cross-bred an Ewok and a bunny that was also the living embodiment of pure joy.
There's a reason vizsla owners often refer to their pets as 'velcro dogs.' Vizslas love to be around people and will stick very close to you, especially if they think you need cheering up or protecting (also, they're ADORABLE )
Westies. Fluffy white balls of cuteness and unconditional love and curiosity. They love people and have the sweetest eyes ever. They're better at making you feel better than any antidepressant in the world.
Record it whenever your cat has a sneezing fit. You'll be glad you did.
A litter of kittens, old enough to chase each other madly about. Running wildly around, stopping for pets at random moments, and then dropping into a kittenpile until they recharge for more of the same.
Gizzmo the Fennec Fox pup. And his Cat and Dog friends.
Hamsters.◊ Especially teddy bear hamsters◊ (the ones with really long fur). I mean, just look◊ at the cute little thing! They're very cute when you put one in a plastic hamster ball and let it roll around on the floor. My mother once watched my hamster do that, and she decided, "You know, if you're depressed, you should just get a hamster." Not without reason did she say that.
Pet rats. Imagine a big, hyperactive mouse that can rest in a scarf and eat practically any human food from pasta to hamburgers. Now realize that this animal has little rounded ears & beady little eyes. Now think of the fact that you can take this critter on a walk around your house, teach it to recognize words, and often give mischievous, playful grins as they scamper about you, each other, and your furniture. In fact, Rupert Grint adopted Scabbers after filming because rats can be That. Damn. Cute.
This puppy and it's whistle. It makes you realize that the good things in life are sometimes the smallest.
Foals Everything about them, with their small knobby little legs and their little hobble walk. So cute.
Going to a natural history museum as an adult, looking at all of the dinosaur displays, and getting flashes of that "Dinosaurs are/were really big and really cool!" sense of wonder and awe from when you were a child. Even better if you can watch actual children demonstrating it with big smiles on their faces.
Oh God, did you have to include the links to the adult animals? The fish especially is Nightmare Fuel. Here◊ are◊ some◊ cute◊ things◊ to make up for it. (That last is a mouse deer, which are a whole category of adorable all on their own.)
Maine Coons! The Gentle Giant of cat breeds. Plus they are very talkative and love to snuggle up to their owners whenever they can.
Birman cats are also giant fluffs of cute! They are known for their docile nature, enjoying spending time with humans and other pets and just have great, relaxed personalities in general, let alone their beautiful blue eyes and their gorgeous fluffy coats! And their white little paws! And! AND! Bwah! Just SO cute!◊
Fireflies. Going outside during summertime, just as darkness is falling, and watching all the slow-moving, flashing bugs. They make me think of stars on earth.
The feeling of belonging. Especially after being the loner for so long, it's delightful and amazing to feel part of a group.
I imagine for a lot of people - conventions and other fan events. There is nothing like this.
Oh, conventions, most definitely. A whole group of people — maybe one hundred, maybe two thousand, whatever — come together just to adore the thing they adore. Everyone enjoying each other's spectrum of creative works, staying out until strange hours, having so much fun that some forget to eat and bathe (a sidenote: if you go to a convention, please eat and bathe.) It's hard to put the right words to that kind of concentrated delight.
Watching a little fawn take its first wobbly steps, first faceplant, and then get back up and start running.
Reading this page after spending several hours reading the old War And Crimes Against Humanity page and and similar, reducing to tears from the sadness. I now have a smile on my face and tears of heartwarming.
The feeling of gratitude that seems to radiate from people after you've organised something, or just done something for them in general.
Christmas morning. Whether you're eight or eighty.
Christmas. Just christmas all together. Just the time before it is the warmest, kindest thing you will ever feel. The decorations, the lights, the food, the feeling of love and kindness and unity and peace. Every. Single. Little. Detail.
Going outside on a cloudless night, and as your eyes adjust to the darkness, seeing the millions of stars in the sky.
Freedom, a disabled bald eagle rescued by a wildlife sanctuary, later returned the favor by comforting her keeper as he recovered from cancer. The description of basically being hugged by a giant bird of prey is awesome with a capital 'aw.'
Knowing that, despite all the scary ass shit in the world (as demonstrated in the 'Others' section of the Nightmare Fuel page), there is a pretty, peaceful, colorful side, is good.
Guinea pigs. They're just adorable. Feeling down, angry, or any other negative emotion? Just watch this.
Especially Teddy Bears.
As we know stuffed animals are a great toy to hold for comfort, whether you've been crying over a breakup, had a bad day, your hope came crashing down or if you're feeling lost and scared. Nobody is too old to hug a stuffed animal for comfort.
Or snuggling up to a real animal (providing it's a domesticated dog and cat that knows you, of course) Just having your pet be with you, feeling him/her beathe in content in your arms...it just reminds you that there's at least one creature on this whole planet that cares about you. After all, who else will take care of him/her?
The sight of a fully lit and decorated Christmas tree.....there's just something so magical about it.
Sunrises. There's something so wonderful about the promise of a new day and a fresh start.
Getting help from a stranger. Be it carrying your grocery shopping to your car, holding a door open when your hands are full, or picking up something you've dropped, few things are nicer than that split-second interaction that somehow manages to be so meaningful. Along the same lines, helping someone out with something, stranger or not, can give you a warm, fuzzy feeling.
This Eastern Screech Owl. Its tiny little call is the most adorable thing, only to be topped off by the fact its entire body literally vibrates as it makes its call!
Keepon, a cute dancing robot that can be used by autistic children to learn social interaction.
Leonardo is a robot that is intended to learn from social interaction. He looks like a Norn (or maybe Gizmo) and is now apparently scared of Cookie Monster (and possibly other blue fuzzy objects). Who doesn't want to hug him?
One of the best excuses to go to Pier 38 in San Francisco during the summer months: the harbor seals have migrated back and they have babies with them!
What about kisses, people?? Whether it's between lovers, family members (not like that, of course!), or between one friend to another who needs to be cheered up, the tender feeling of someone's lips against your face can make even the bleakest day seem brighter.
It's hard to tell if this is Sweet Dreams or just plain Heartwarming (maybe both!), but the moment where you fail at something you've been trying to do for ages and ages... and then realise that you did better than last time and you're so much closer than you were when you started.
Happiness is a warm and fuzzy animal.
A kitten falling asleep on your arm and purring its little heart out. Annoying? Yes! The most wonderful feeling in the world? Yes.
Boots the dog is a "kitten nanny" that spends one day a week with rescue kittens, helping them get used to dogs and making sure they have a wider range of homes to go to when they're eligible for adoption. The photos of him with his charges are absolutely adorable.
This photographer rescued a little black cat from a shelter. He also happens to be an amateur rock climber and when he noticed his cat's natural climbing abilities, brought her along to his climbing adventures and it is adorable.
Surprise birthday parties. Your loved ones go out of their way to show you how much they appreciate you, and go to the effort of keeping it secret, just to celebrate you and your life.
Really, any party thrown for you, whether it's a birthday, wedding, whatever.
Weddings. People decide, "You know what? I want to spend the rest of my life with you. I love you enough that whatever happens, wherever we end up, I want you in my life forever." That's pretty darn adorable. And taken Up to Eleven when you can watch one of your friends/family do this, or even better, two of your friends decide to get married to each other.
Beaches during the night, especially due to the soothing sound of the waves.
