OK, I’ll give Scavenger Hunt a try, for 200.
Answer:
THIS is a topic with an animal mentioned in the title.
What is Outdoor cat in Michigan?
What is “Outdoor cat in Michigan”? You didn’t specify anything but an animal being in the title.
Famous Topics 100
Correct!
Oh that would have worked, Captain Carrot but if you could also link to them… 
Just to denote the person actually found it instead of just remembering it.

Let’s try “Famous Topics” for 400, Idle Thoughts!
Oh, and nice to be back in this, thanks! Although I found it a little late. Stupid work.
Good thing that the one who was first did that anyway, as that would be an annoying technicality; though I’m sure we could resolve this sort of thing easily, not being a strictly-governed show.
Answer:
Coldfire once made a topic about THIS date.
What is May 5, 1945?
Just out of curiosity, would you have accepted My fine feathered friend as a thread with an animal in the title? How about Firefox 2.0 released?
True…but someone could probably just say any answer for some of the harder ones in that category and nobody would know if it were really a topic or not. Hahaha.
To be fair, I didn’t make any of the rest things that were too hard to find and in my defense, it was the last category I added just to need one more.
What is May 4th
Dammit, I got the post but I had a typo on the date.
Correct!

For the first I wouldn’t have, Mbossa but just because it didn’t have a specific animal name in the title, however I would have with the firefox thread. 
Actually, the dates in the OP on that one are confusing. He says they remember May 5, 1945, but then he says that they observe it every May 4th. Silly Dutch!
Let’s go with Famous Topics for 200, Idle Thoughts!
Ohhh hahahaa, poor you.
I only ask for the links to the threads just for the scavenger hunt category. No other. : p
Just the answer is fine, if you know it.
I feel better then.
