Temperament:

TICA:  Temperament must be unchallenging, any sign of definite challenge shall disqualify. The cat may exhibit fear, seek to flee, or generally complain aloud but may not threaten to harm.

Evidence of intent to deceive the judge by artificial means, cats with all or part of their tail missing (except those breeds whose standard calls for this feature), totally blind cats, cats having more or less than five toes on each front foot and four on each back foot (unless proved to be the result of an injury or as authorized by a board approved standard), male cats in the adult championship class which do not have two descended testicles, and, at the discretion of the judge, tail faults (visible or invisible) and/or crossed eyes shall be disqualified from championship competition.

ACFA:  Same as above.
