You might be thinking of "Cat Pictures Please" by Naomi Kritzer, which can be found online at Clarkesworld: http://clarkesworldmagazine.com/kritzer_01_15/

Yes, that's it! Thanks for the link.

There are two novel spinoffs of it as well now. Catfishing on CatNet is the first one and Chaos on CatNet is its sequel. They're pretty cute.
