I entirely disagree that it's dying. In my unique experience, it's merely leveled off, and site activity is low because this isn't exactly meant to be a full-attention game. This is something you poke at every now and then to maintain your pets and plants and expand your collections. It's not like Neopets with a giant team of developers and artists that are constantly making new games and site-wide events to keep the players actively engaged for as long as possible.

That being said, I do have a somewhat unique perspective being at the top of the sponsor list in that I get a lot of pet interactions from accounts that I've never seen nor interacted with myself. I get new accounts coming through my feed all the time, multiple per month, and that number has stayed relatively steady for the past 2 years of sponsoring the site.

Once the new accounts stop rolling through, I'll agree that it's dying, but until then, it'll be business as usual; a passive game for people to enjoy slowly. It's very engaging up front when everything is new, and tapers off over time as the grind settles in. I go through bouts of active and inactive, myself. Some months I'm really engaged every day, and other months I barely see the home page. It happens!
