I have long since loved the cyberpets that you adopt online and keep on your computer or website. While I do love Neopets and many other similar pet sites today, I'm really talking about the ones once found on Yahoo Geocities and Angelfire websites in the late 90's and early 2000's. They might have short backstories or come with accessories, but often enough you just took one by itself. However, many of these were lost when Geocities shut down and domains stopped getting paid for.
But some are saved by the Web Archive, and a few I saved to my computer long ago... here is a home for the cyberpets I have adopted!
