Two of my most recent additions were my Dog Facts and Cat Facts sites.  I did theses sites on a whim, and truth be told, I actually don't have any pets.

I spent most of June this year putting them up.  I think I have enough information on the cats site but the dog site seems like a much larger topic to complete.  If it ever gains any popularity - I'll add more to it.

One month later, the verdict is still out as to whether these sites will get any traffic, but there is usually a long wait period before web sites are fully indexed by search engines.

I think people will enjoy these photo sections for each.  Go ahead, click on the icons and take a look - I dare you.  You obviously have nothing better to do if you've actually been reading anything on this site.

Note (April, 2007 update):  A new section on Maniac World now exists for Cat Videos and Dog Videos.
