The tigers are actually since a longer time a part of the Sultanates than the Fennekim. But for long they had been only individuals lost in the vast majority of the amazones.
Only since the Fennekim, themselves being carnivores, too, brought their ingenuity in regards to foodstuffs to bear, do the tigers sort-of prosper in the Sultanates.

However, most of them live a code of Gimu, life dept to the amazones, why they never fight and avoid training how to fight, from fear their insticts, their reflexes could ever break through.

The Fenwas however, do teach a select few - and tigresses only - some of their secrets.
Officially it's about dancing and soothing wounded minds, killing the nightmares of a hurt soul. Some, however, usually those that risked their life to protect children of the other member-species of the Sultanates, are also taught to control themselves, and to control their insticts.

They never talk about THAT part of their training in public, and aside the belted knights of Fennekim Lore, they are most likely the only ones ( Aside of the Stratega and the Princess ) that know about what an aroused and angered Fenwa can do, as they regularly attend the contests for marrying rights of the Fenwas, as only their strength and skill - and "damage capacity" can help to patch up the winner of such a contest.
