The link was for petproject.com. I haven't looked all that much on the page, but they have a link for "Feed a Pet" and it leads to Feed a Pet Trivia.
|Answer questions to feed pets.|
The idea is to answer questions, and every time you level up, the page donates food to one shelter pet. There are all sorts of categories to choose from - not just pets - and I happily clicked in states, flags, chemistry, the periodic table...
Turned out I was nowhere near as good at these things as I expected, and I ended up with just dog breed questions. That I was pretty good at.
