Obsessive and Quirky

Tabaxi have an innate obsessive curiosity fixed upon something specific, be it a monster, magic item, legend, or location.  On top of this, they possess a personality quirk that can fit in their Flaw box on their character sheet.  Volo's Guide to Monsters has a table for this, or you may of course create your own.
