Cane toads ooze a milky, toxic substance called bufotoxin, which is deadly to cats and dogs if they bite, sniff or lick the giant toads. The toxin is also dangerous for humans, and people should wear gloves and protective gear when disposing of the toads, according to the Florida Fish and Wildlife Conservation Commission. Cane toads are native to South and Central America and first brought to Florida to manage pests in sugar cane fields in the 1930s, according to the University of Florida. Now cane toads are reported in Central and South Florida, usually south of the I-4 corridor. Click on the icons below to see reported cane toad sightings in Florida.
