speakAsCat

• Compact IRI: firefish:speakAsCat
• Canonical IRI: https://joinfirefish.org/ns#speakascat

Used on actors to indicate that they not only identify as a cat, but also want to have their text be transformed to speak like one, expressed as a boolean value. If this property is set to true, displaying the actor’s posts will make them speak with “nya” instead of “na” and other cat-related text mannerisms. Used in combination with misskey:isCat.
