Afflicted cats exhibit excessive attention-seeking behaviour such as tormenting prey when you can witness the grand event and sulking if you don't respond gratefully to their gifts of decapitated mice. Any cat which has ever received an Oscar nomination is an advanced sufferer. The owner of a histrionic cat is the one whose cat story is always one-up on everyone else's cat story. Under no circumstances should you ever attempt to upstage a Histrionic Cat. It knows that it is best admired when sitting right in front of the TV screen, obscuring the main action.
All cats are narcissistic by nature, some more so than others.
Alleviating these symptoms may provide a temporary respite from the disorder. Try using a music stand when reading newspapers. Highly independent and rarely seen, this cat is usually invisible. Some owners can go for years without knowing what their cat looks like. If it rubs against your leg it isn't a sign of affection, it means the doorway is narrow.
