Reduced spawn timers or am i just very lucky?

[Gizmo]

I got bored and decided I would log onto my troll hunter that I have been levelling and look for some unique rare pets with only going to each's spawn point once and this being my first attempt at finding any of them I managed to get Olm the wise, Silithid Harvester, Zacriotl, Shadowclaw, Duskstalker, Rak'Shiri, Ashtail, Tsul'kalu, Rex Ashil, Zora, Deathmaw and Old Cliff Jumper, being level 64 the only two tameable rare and unique pets I didn't find were Pogeyan and Spiteflayer. Anyway question is have they reduced the spawn timers on these pets by a lot or did I just get lucky?
I used http://www.wow-petopia.com/browse/collector.html to find out about them

Blizzard reduced spawn timers dramatically at the release of Cata.

Yeah, most of them are still a good 4-8 hours though so you still got quite lucky.

A lot of those have closer to a 12 hour timer to my knowledge while others are closer to 4-8 but regardless that is quite the catch! Grats <(^_^)>
