I must say does it love corn, cause in Jamaica were I live their is a lot of corn and I plant some at the front of my yard and other neighbour has corn too.
No it's not dangerous.. And no it doesn't like corn, it's a carnivore 100%.. They got the name because they were often found in corn fields where they hunt the mice and rats that do like to eat the corn.
I can't find any evidence of corn snakes in Jamaica...but then there isn't much of anything about snakes in Jamaica. What I have learned is that there are NO poisonous snakes in Jamaica.. so whether or not it's a corn snake it's harmless.
If you're not planning on releasing it soon, you need to get a pinky mouse or little lizard to feed it.
Here is a page all about the corn snake the reason there are no poisonous snakes Jamaica is that they imported the mongoose to get rid of them. en.wikipedia.org/wiki/Corn_Snake www.instanthawaii.com/cgi-bin/hawaii?Animals.mongoose
