As far as I can tell, Greeks in Greece don’t actually own pets. I will admit that this presumption is based on limited observations, but I’ve really never seen anyone there with the stereotypical pet. One of my cousins once had some small birds (parakeets, I think), but I just don’t recall ever seeing anyone with pets like dogs or cats. Now don’t get me wrong, cats and dogs are definitely there. They just don’t seem to “belong” to anyone.
