Sian-Rotam

Sian-Rotam is a level 53 rare white lion that can be found in northern Winterspring. He used to be a summoned mob for a horde-only quest where he would appear and help defend his mate, Shy-Rotam. In patch 2.3 the quest became available to alliance as well. Now Sian-Rotam is no-longer summoned and is simply a rare spawn that can occasionally be found sleeping behind his mate underneath Frostsaber Rock. He will not patrol away from this location once he spawns in.

Sian-Rotam has always been a desirable hunter pet, especially for alliance. The only other tamable white lion in the game is Echeyakee. Echeyakee is a level 15 spawned lion from a level 13 horde-only quest that starts at the Crossroads in Northern Barrens. If you play alliance, unless you get very lucky or have a friend playing horde who can help you, Sian-Rotam will probably be the easier of the two to obtain.

Sian-Rotam can be found with NPCScan, but it isn't really necessary as he doesn't move from the location that he spawns at. If you do choose to add it, his NPCScan ID is 10741.

I don't know much about his spawn timer but I did have to check his spawn location several times before I finally snagged this pretty kitty.
