I am glad the mother in law is doing well from the shot. That is pretty frightening....
I am curious to why " county authorities actually encourage residents to shoot or trap troublesome armadillos."
Thinking that armadillo's were harmful creatures, I looked it up on Google and found out that they are not that harmful unless handled incorrectly. But thats the case with all animals...
"They are wild animals, and any wild animal should be treated with caution and respect, but the average armadillo is not a dangerous creature. They are capable of harming people with their strong claws if they are handled incorrectly, but in most cases they will run away when they feel that they are in danger."
