"Nine-banded armadillos are odd-looking creatures, about the same size as a domestic cat. While not native to Florida, they are common throughout the state, including at Walt Disney World. They gobble down insects, other invertebrates and plants and are most likely to be seen at night"In over 20 years and more than 30 visits to WDW I've never seen an armadillo, so I will defer to you one this one. If they are that big a problem on property then the signs should read something like Warning. Do not feed and stay away from all wildlife at WDW.
