I know that there will never be a true count cause of al lthe crap some people have ot go though to just have a ball python , but they can go get a " fighting dog" breed with less hassle or crap to get a pet, nd ther more of them killing people than there are of snakes.
I know several people that keeping snakes in delaware alone with out permits cause some of the requirements are stupid,
( example) need 1 acre of land ( but on a 1/4 arce I cn havea cow or goat , aswell as dogs. (which all go outside and make messes buyt snake will nolby be out if the owner taking pictures or taking to a vet) so tell me which more dangerous. ( i seen several guys runnnig around with the so called dangerous breed dogs and the cop just rides by but I bet if i had my snakes up here and walked outside with it to go home or to a vet I get my snake taken, fined and everything else.
