hiraizm seems to be an account that reposts other artists' images. As linked in the source tweet, the original artist is a Malaysian named Kamwei Fong who has an instagram here and an etsy here. Based on the description in the etsy's about section, this image and its children are part of series called "The Furry Thing" which also includes monkeys and dogs. The artist has a habit of posting multiple versions of the same image to advertise them as etsy prints. This image was likely first from here, which also happens to be Kamwei's first post of the illustration.
