What eats Ringtails?
Great horned owls, bobcats and coyotes.
There are several species of animals that are more or less closely related to the raccoons: coati, kinkajou, ringtails, cacomistles, and olingo. Of these, the ringtails and cacomistles probably look most like raccoons (they're also the most closely related to raccoons). Red pandas are a bit more distantly related, but are kind of similar in appearance to raccoons also (if you're colorblind).
