Oddpets are simply any other type of virtual pet. This has the widest variety in pets, which means there is simply no information on many of these.
Information on this page relies heavily on Tamenagerie, my own experience, the OddPet Haven Discord server, and a whole lot of Google.
Organization will be done to the best of my ability, but with the large variety of pets available, it's not going to be perfect. I recommend utilizing the search feature if there's a specific pet you're looking for!
Many of these pets have little to no information.
