I know In delaware you ( now ) required to get a permit for each none native snake you want. I am not sure how that effects vemonous snakessince I don't keep any. I do know they not really changed it as ofright now as in some parts you can't own a snake unless you own x amount of land but you can havea horse, goat or whatever animal wise.

I do believe that a person should be held responible for their pets, I know thatyeah escapes happen and such but I also think letting neighbors know( warned) and the spca incase the animal is seen outside the home would be helpful specially if the neightbor willing to call and let you know . since retriving it would prevent an attack.
I do call and update the state Permit ) office about 1-2 times a year as to what I am housing so as to prevent any issues incase ther ever a complaint. Might be why I get some slack cut .. I know of several of my past rescue were given up cause people found out they were not able ot get the permits or such.
