Marapets .com!
It's another virtual pet site but I guess you could say the graphics aren't as good? But I happen to enjoy it a lot. You can do pet trading and all kinds of stuff on there. They have their own system and everything. I like the quests better but you can also collect a lot of things like plushies, plates of minipets (like petpets), and photos of different costume (painted) pets and stuff and they have prizes for collectables. They also have missions you can undertake where like they'll ask if your pet has read certain books and stuff and like each level you go the rarity of the item asked for is higher but a lot of their missions you can win LE pets and stuff like that.
There's much much more but that's a small example.
