Add Cat mounts

[Legion88]

care to explain your last comment?

Every expansion has its own theme for the trial/primal mounts which drop in the extreme modes of the encounters.
ARR primal mounts: horses/ponies
HW primal mounts: birds
SB primal mounts: dogs/wolves
future expansions (5.X/6.X...): maybe cats

Also Tiger mount is available for a hunt achievement.
Panther is also in some kind available via DRK tank achievement, if you caunt couerls as cats or feline.
