Simon's Cat is a British animated web and book series written by Simon Tofield. It features a fat, hungry white cat who uses various tactics to get his owner to feed him.

Following the success of its first animated films, it was announced in January 2009 that Simon's Cat would be published in book format.^[1][2] Canongate Books released the first book on October 1st 2009 in the United Kingdom, which was later released in 26 other countries.^[3] Since then, 9 more titles have been released.

In June 2012, Walt Disney Animation Studios began releasing specially-made shorts of Simon's Cat. In addition to the shorts, the Daily Mirror ran a Simon's Cat newspaper strip, which ran from 2011 to 2013.^[4] Later, in August 2015, it was announced that Endemol Shine UK had acquired a stake in Simon's Cat.^[5]

In May 2016, Simon's Cat partnered with the American children's television program Sesame Street as part of their Love to Learn campaign.^[6]

Later on, many game developers made a variety of games based on Simon's Cat. In June 2017, the game Simon's Cat Crunch Time was created. In February 2018, Simon's Cat Dash was created, but as of 2023, this game was no longer available to download and was only available to download on a website named Uptodown. In June 2018, the game Simon's Cat Pop Time was created. In April 2021, the Apple Arcade game Simon's Cat Story Time was developed.

Simon Tofield, who has over 13 years of experience with animating commercials for companies such as Marmite and Tesco,^[7][2] came up with the idea for his first short film as a way of teaching himself how to animate using Adobe Flash.^[2] He also revealed that the inspiration for the series came from his experiences with his four cats – Teddy, Hugh, Jess, and Maisie, with Hugh being the primary inspiration.^[8][9]

• Cat: A hungry fat white cat, the main character and the star of the show. His antics include his quest for food. His signature gesture is to point at his mouth or bowl and meow when hungry, and other ways of vexing his "owner", Simon. Besides eating, he also enjoys chasing birds, mice, and catching fish out of Simon's pond. His efforts in these endeavors create a significant amount of the humour in the book. He has not been officially named, although writer Simon says that he is based on his own cat, Hugh (in the show, Simon has been hinted to call his cat Gilbert).^[12]
• Simon Tofield: A human, the long-suffering owner of Cat and a graphic artist. He is shown as good-natured, gentle, easily startled, and accident-prone. As shown in the episodes "Scary Legs", "Scaredy Cat", "Spider Cat and "Bat Cat", he has arachnophobia. Simon is from Leighton Buzzard, Bedfordshire
• Kitten: A kitten, the playful little brother and the sidekick of Cat, who first appeared in the episode "Double Trouble." He was brought home by Simon in October 2011. In spite of his tender age, he appears to be considerably smarter and more cunning than his big brother. Kitten will point to his mouth or bowl and mew when hungry, just like his big brother. Like Cat, Kitten has not been officially named, but is based on the 4th cat, Teddy.
• Simon's Sister's Dog (named Oscar): A dog who first appeared in the episode "Fed Up!", in which he's fed underneath the table by Simon and the family. He also appears in the book and he likes to play fetch. It's revealed that his name is Oscar.^{[citation needed]}
• Bird : A bird or robin who Cat chases. He generally outsmarts him. And is also featured as a squeaking toy bird or even a Christmas ornament.
• Hedgehog: A hedgehog who lives in Simon's back garden. Cat likes to annoy him by impaling objects such as apples, leaves, and tennis balls onto his prickles. He has children and he also has a girlfriend named Daisy, who is a hedgehog like him.
• Bunny : A rabbit who lives in Simon's garden. She has the ability to hop and run in circles around Cat.
• Squirrel : A squirrel who lives in a tree in Simon's backyard. He loves to pelt Cat with acorns when he chases him.
• Garden Gnome : A garden gnome who likes to go fishing. He is similar to the one broken by Cat in the episode "Let Me In." He is seen holding either a fishing rod, a net or sometimes a checkered flag in the episode "Ready, Steady, Slow!." Cat often tries to get him to help in his schemes to catch food. Cat considers him a friend, apparently unaware that he is an inanimate object.
• Toad : A toad who lives in Simon's garden. He is similar to Frog.
• Frog : A frog who lives in Simon's garden. He appears in some episodes as well, and he is differentiated from Toad in the "How to Draw... Frogs and Toads" video as well as in the "Simon Draws" section of the Kitten Chaos book.^[13]
• Chloe : A girl cat who wears a heart collar. She is the love interest and girlfriend of Cat. Chloe is depicted as demure and somewhat snobbish, as well as exhibiting a finicky appetite, munching on a trail of cat treats or even butterflies, but angrily refusing Mouse offered by Cat.
• Mouse : A mouse who is often chased by Cat. Despite their adversarial relationship, he aided Cat in an elaborate plot intended to impress Chloe in the episode "Smitten", later helping him to get food in another.
• Maisy : A Tabby cat who falls in love with Cat, even though it is shown that he has grown to be terrified of her.
• Crow : A crow who sometimes annoys Cat.
• Jazz : A grumpy territorial Persian cat and arch-nemesis of Cat who Cat often gets into fights with.
• Teddy : A stray cat living in a box who Cat befriends. As of late 2022, he appears to have found a forever home. Though he lives with a neighbor, the story of Teddy is actually based off one of Simons own rescue cats.
• Muffin : A puppy who first appeared in the episode "Pup sitting." He is playful when Simon feeds him dog treats. He's also shown to be energetic, but also scared of rain and lightning.
• Tess : Tess is the owner of Teddy and a neighbor of Simon.
• Simon's Sister : She is the owner of Muffin and like Simon is from Leighton Buzzard, Bedfordshire.

Also, Simon's Cat: Pop Time, a video game for iOS, Android and Amazon Kindle,^[45] was nominated for "Best Casual Game" and "Best Puzzle Game" at The Independent Game Developers' Association Awards 2018; another game for iOS and Android, Simon's Cat Dash,^[46] was nominated for the "Heritage" award.^[47][48]
