An Animal Planet series focused on baby animals in all their cuteness. Most episodes feature three litters of either Cute Kittens or Precious Puppies for the first ten to twelve weeks of their lives, showcasing various milestones while being as adorable as possible.
"Sweetest Animal Friends" features old clips from the Domestic Shorthairs of "Kittens and Pocket Pets", the Mini Australian Shepherds of "Puppies and Ducklings", and the Ragdolls / German Shepherd of "Kitten Dolls".
"Fluffiest Kittens" features old clips from the Siberians of "Kittens and Pocket Pets", the Persians of the very first episode, and the Maine Coons of "Kitten Cottonballs".
Edible Theme Naming: Butters and her kittens Noodles and Cheddar, Tonkinese brothers Muffin and Cookie, Shar Pei brothers Raisin and Pancake and their sister Peaches, mini pot-bellied piglet Pretzel, Munchkin kitten Porkchop, Shiba Inu puppy Cinnamon (as well as her mother Spicy), Japanese Chin mom Cookie and Cocker Spaniel puppy Coffee. Singapura triplets Pepper, Saffron and Basil from the same episode as Porkchop follow this for condiments, as well as Burmese kitten Pepper.
The Domestic Shorthairs were raised in a New York apartment full of various animals, most notably alongside a guinea pig named Ariel.
German Shepherd Mari with the tiny Ragdoll Snowball.
As well as Jaegar, another German Shepherd, with tiny Toyger Tanya.
It takes a little patience, but Maggie the mini Potbellied Pig eventually warms up to peppy Penny, a Springer Spaniel.
Bassett Hound puppy Max and hamster Dot.
Cow Cat kitten Moo and his adopted skunk brother Duke.
Coton de Tulear puppy Snowflake and her adopted pygmy goat sister Pipsqueak.
Siberian kitten Boris and miniature pony Kitty.
The Cornish Rex kittens and Timber, yet another German Shepherd.
It takes a little while before the hoglets eventually warm up to Doodle the long-haired Dachshund.
Tallulah the Syrian Brown Bear cub forms one with Kai, yet another German Shepherd.
Merlin the Airedale Terrier puppy and Jerome the goat.
Irony: The Portuguese Water Pups don't like water! Domino eventually gets used to it, while his brother Ace... not so much, but he withstands a bath with Domino's encouragement.
It Runs in the Family: Rory the Chesapeake Bay Retriever puppy inherited the white diamond-shaped mark on his chest from his grandfather, who was a champion show dog. His cousin Thor also has the mark.
Tiger sticks close to mother Jas Queen as much as possible.
Moose the British Shorthair always wants to be by mother Roxy's side. Amusingly, their coat patterns match almost completely.
Percy the Standard Poodle puppy always does what his mother Lotus Rose expects of him.
Multigenerational Household: Alongside their mother Beth, the Chihuahua puppies live with their uncle Coco Puff and their grandparents Montana and Ned. Their great-grandma Hannah even lives right next door.
Musical Theme Naming: The European Burmese kittens follow this trope. To be specific, two of them are named Ludwig and Melody, which makes a lot of sense since they're reared in a music teacher's house.
Shaggy Dog Story: Played for Laughs with the Ragamuffins: unlike most cats, they dislike climbing, so when Otto tries to reach the food on the counter, it's an epic journey... only for their owner to put the plate down on the floor right as he makes it up.
Shout-Out Theme Naming: Himalayan mother Ariel and her twins, Jacques and Belle, are all named for Disney characters (two Disney Princesses and a mouse friend of a third).
In a later episode, two Savannah kittens are Zazu and Nala, after characters from The Lion King.
Boots and Little Bear's father King Arthur is named for, well, King Arthur.
"Sweetest Animal Friends" is a Clip Show that focuses on the stories of 3 litters from previous episodes: the Domestic Shorthairs (Noodles, his brother Cheddar, their siblings and their mother Butters) from "Kittens and Pocket Pets", the Mini Australian Shepherds (Finn, his sister Jojo, their siblings, and their mother Rosie) and the ducklings from "Puppies and Ducklings", and the Ragdolls (Snowball, her siblings, and their mother Ruffian) and Mari the German Shepherd from "Kitten Dolls".
"Extra Special Pets" focuses on pot-bellied piglets, lop-eared bunnies, and hedgehog hoglets.
"Fluffiest Kittens" is another Clip Show, that focuses on the stories of 3 kitten litters from previous episodes: the Siberians (Mittens, her sister Socks, their four siblings, their mother Solomeya, and their stepfather Maksim) from "Kittens and Pocket Pets", the Persians (Reginald, his sister Gizmo, their sister Priscilla, their other two sisters, and their mother Truly Elegant) from the very first episode, and the Maine Coons (Dante, his sister Lulu, their three siblings, their mother Sierra, and their father Sabu) from "Kitten Cottonballs".
Two "Animal Best Friends" specials focus on Tallulah the bear cub and Kai the German Shepherd, Joey the kangaroo and his Muntjac deer pal Darby and Poppi the lemur, brown lamb Cocoa and his goat buddy Sapphire, Snowflake the Coton de Tulear puppy and Pipsqueak the pygmy goat (the only friendship from a previous episode), baboon infant Josh Earl and his surrogate father Poncho the Golden Retriever, and Minnie the Flemish Giant rabbit and her best friend Tinsel the Teacup Pig.
An episode titled "Baby Sloths" features only two actual baby sloths in focus, though a few others are seen; however, much of the special focuses on the adult sloths in a rescue sanctuary, and it's generally a complete stylistic break from the rest of the show, even including the founder and employees of the sanctuary in the story. It also is probably the only episode that will ever directly mention death. It is, however, still too cute.
