Pet Sites!
Here's a list of pet sites and avatar dress-up sites that I like to play on. Most of them have been around for a long time, or are recreations of older sites that have been lost or sold off. Others use your own art and writing to progress. Sign up and have fun!
Flight RisingA site where you collect and breed dragons, with a ton of variety in genes and modifiers. You can also dress them up, roleplay, write large bios, etc.
Gaia OnlineAn avatar dress-up site with a pixel aesthetic. There is a MASSIVE variety of avatars and games, and a very robust forum system as well.
AywasA very classic pet site with a human avatar dress up option. You level your pets and catch new pets in Adventure mode, and they still hold several holiday events every year. I'm proud to say that I've caught every available Phanto so far!
Neopets ClassicA recreation of the original Neopets in its heyday, before it was taken over by commercial interests, and later infected with NFTs. All of the original flash games work, and the userbase skews older, mainly 20s and 30s.
