Kavats are a type of companion, similar in appearance to cats. Kavats normally live in Infested areas and feed on the Infestation. Wild Kavats are naturally invisible and are not hostile to players unless they are scanned. Due to their anti-Infested potential, the Grineer have domesticated Kavats for use in clearing out the Infestation from their ships. Kavat handlers, known as Hyekka Masters, are equipped with advanced sensors to detect Kavats, which can also detect invisible players, serving as an additional stealth hazard in Grineer missions.
