Any sighting of the elusive Big Cat?

Went in Room 0, and saw a nub trying to capture it, i was thinking to steal it, but im like nah.
CC'd to chan 5 didnt see anything so i cc'd, soon as i cc'd i saw the blue text appear, so i cc'd back. Good thing its still there.
Caught mines, then cc'd to chan 3, found another one, and gave it to guildie.

What world? (How long before the SS did you first see each Jaira?)

Information from the Map.wz file:
The WZ files show almost no information to help us. There is one map, 931000500 (iirc), which lists all the mobs in the map, but doesn't list Jaira (this could also be why Jaira doesn't have a specified spawn location, there isn't a specified spawn location in the WZ file map data). All the other maps link to this map (as in, they are copies of this map), and no mob information is given. The only difference between the mobs listed in the map is that one of the tan/brown jaguars (I forget whether it's top left or top right, but I don't think it makes a difference) has a mobTime of 0, the rest of the jaguars have a mobTime of 1. I'm not sure what mobTime does, but I thought it might be worth pointing out. And no, killing this tan/brown jaguar does not spawn Jaira.

There are a total of ten maps. 00, 09, 08, 07, 06, 05, 04, 03, 02, 01. They go in order as listed. If someone is in the first map (00), and no one is in the second map (09), you will be placed in the second map. If there is one and only one person in every map, you will be placed in the first map, and it cycles like this. Once you are in a map, you can change channels, and you will still be in that map.

Information from the Mob.wz file: (Jaira in general)
Jaira takes 5 damage per hit, constant, similar to all jaguars except the normal black ones. Jaira cannot be KB'd, and he has 300 health, compared to a normal jaguar's 125. For what it's worth, a normal black jaguar takes 25 damage per hit, constant. The most valuable piece of information gained here is that Jaira, once spawned, will disappear after 15 minutes.

Even if you are currently riding a jaguar when you catch another one (Jaira included), you will automatically switch to the jaguar you just caught, so don't be afraid of riding a jaguar while trying to catch Jaira.

Jaira is similar to an area boss in that after he spawns, the first player to enter that map will receive a blue message saying "Jaira has appeared from between the boulders". That does not mean that this text will always appear, people might receive the text and leave, or be afk in the map with a Jaira present. Do not channel surf waiting for the text.

I added the reports that gave enough information, and requested information I didn't have in the quotes above. Congratulations to everyone on catching their Jairas! And to everyone thanking me for compiling the list, I'm glad it has been useful, you're all welcome.

Also, to the people asking about a pattern/when the best time to catch it is: I haven't been able to develop a pattern since the three-day break of no reports. Any pattern I've come up with since the last one failed has been thrown out the window because of those three days of no reports. So, in essence, I have no idea. Keep checking, and you're more likely to catch it. Sorry, I know that isn't very helpful. :\

Edit: Updated the reports to include information I requested (and deleted those requests). Thanks for the quick responses, guys!
