Trait overview

Only one blood group system has been established in domestic cats - the AB system. There are three feline blood groups: A, B and AB. A fourth group - MiK - has also been identified, but not much is known about this group yet, other than the fact that it is very rare (occurring in less than 1% of cats). This is considered the most prevalent feline blood type, with more than 90% of cats estimated to have blood type A.
