A "tabby" refers to a specific coat pattern commonly found in domestic cats. This pattern is characterized by stripes, swirls, or spots, often accompanied by a distinctive "M" shape on the forehead. Tabby cats can come in various colors, including gray, brown, and orange, and they are known for their friendly and playful nature. There are several types of tabby patterns, including classic, mackerel, spotted, and ticked. Each type has unique markings that differentiate them from one another. Tabby cats are not a specific breed but can be found in many breeds, making them one of the most common types of cats worldwide.
