A total of 99% of the domestic shorthair cats in the United States have which blood type?

• A. B
• B. A
• C. AB
• D. O

Answer: (B)

In cats, there are three main blood types: A, B, and AB. The domestic shorthair population in the United States is overwhelmingly type A—about 99% carry this type. That’s why type A is by far the most common blood type you’ll encounter in these cats. Type B occurs in smaller percentages, with higher frequency in some purebred lines and certain regions, and AB is rare. Clinically, this means transfusion planning for the typical domestic shorthair centers on blood type A compatibility, though crossmatching is still important to prevent any possible reaction from antibodies.
