Tuxedo cats (or TCs) are significantly more intelligent than regular cats (including all other breeds and varieties).
Research indicates that this difference may be as great as 200%.
Other cats living in the same households as TCs benefit from this and may see temporary increases in intelligence of 5-10%.

TC’s are significantly more intelligent.
I guess we can’t for all purposes call Obama a TC.
