Here's why:
* Classic Tabby Pattern: This pattern features a distinctive "M" marking on the forehead, vertical stripes running down the back and sides, and "bulls-eye" markings on the flanks (which could be what you're referring to).
* Other Tabby Patterns: There are several other tabby patterns, including mackerel, spotted, and ticked.
* No Breed Called "Bulls-Eye Tabby": There is no cat breed specifically known as "bulls-eye tabby." Tabby patterns can be found in various breeds like American Shorthair, Maine Coon, Abyssinian, etc.
If you can provide more context about where you encountered the term "bulls-eye tabby," I might be able to give you a more precise answer.
