Hi Serene,
Thanks for discovering that. However, I wouldn't really consider that as an "abuse"... it's actually more of a "misplacement". That's because right now we don't yet have proper facilities for people to list and sell pets & pet-related items... so they do not know how best to place the listings.
We will soon be making available proper facilities to mark the corresponding pet statuses, as well as listing and review of relevant products / services.
With the proper sections in place, we will definitely be able to grow PetFinder much faster by drawing in a wider community of audience, which directly translates to higher exposure for the homeless pets and more successful adoptions.
p/s: I'll keep a lookout for pugs and let you know once we have them for adoption, so you can get a companion for your lil' Rocky!
