Minecraft wiki entry for Cat, associated text: The tuxedo cat is based on Jeb's pet cat, Newton,[7] who died in 2014.[8]
The Jellie cat is based on GoodTimesWithScar's cat, Jellie.
In MINECON Earth 2018, Jeb announced that the community could vote for a 9th cat skin to be added with the rest of the other 8 cat skins. As a result, GoodTimesWithScar’s cat Jellie won the contest and was added in Village and Pillage, making the second mob variation that was suggested by the community, the first being "Toast", a rabbit skin.
Both calico and white cat appear to have heterochromia.
The calico cat skin's fur pattern resembles that of Winslow, from Minecraft: Story Mode, with the only differences being the eye color and the mirrored fur pattern. The episode in which the cat appears was released two years before calico cats were added into the game.
In real life, cats have been known for their ability to flip upright during a fall, particularly larger ones; though they still might be injured by landing. This fact is reflected in Minecraft because they are not damaged by falls.
The current Siamese cat texture is unused in Bedrock Edition.
In real life, calico cats are almost always female and the few male calicos that do occur are generally sterile. However, since animals in Minecraft are genderless, it's not odd to breed two calico cats with each other.
