Not to mention that cats and dogs get into the garbage, use the washroom in your front yard, carry around fleas, and bark all the time!!!
Don't get me wrong I love cats and dogs, probably just as much as reptiles, but most reptiles are harmless.
And how often do you see a snake loose anyways, I'm pretty sure nobody purposely lets them get out.....I could probably count at least 3 loose cats a day.
I think that if somebody wants to own a reptile then it's their choice, but if it gets out...it's their resposibility. I don't think banning is necessary.
Just my point of view anyways...
