Here are some possibilities:
* Domestic Shorthair: This is the most common breed and can come in a wide variety of colors and patterns, including orange and white.
* Domestic Longhair: Similar to the Domestic Shorthair, but with a longer coat.
* Siamese: Known for their striking blue eyes and pointed coloration, sometimes including orange and white markings.
* Calico: A tricolor pattern (usually black, white, and orange) found in several breeds.
* Orange Tabby: This isn't a breed itself, but a color and pattern common in many breeds.
To get a better idea of your cat's breed, you could:
* Look at its physical characteristics: Body shape, tail length, ear shape, etc.
* Consult a veterinarian or cat breeder: They can help you identify possible breeds based on your cat's appearance.
* Do some online research: Websites dedicated to cat breeds can help you compare your cat's features to different breeds.
Remember, a cat's personality and temperament are more important than its breed!
