Pretty snakes you got. I had boas, kings, gophers, whips, garters, and one pathetic water snake. My favorite was the mountain king snake, absolutely beautiful.
I am not going to worry too much if someone’s stinky parrot gets away and lands in my backyard. But if their cobra gets away and crawls into my backyard, then that is problem. You sound like a responsible owner. Fortunately this is not a common hobby. The discipline it would take to safely keep something like a cobra would spoil all the fun out of it for me.
It’s more common that you might think but I agree, the level of attention required for a hot would take the fun out of it.
I’ve handled and dealt with a lot of hot snakes and they’re not that bad but I’m not interested in keeping them. I made it a point on knowing how to handle hots though. I do a lot of snake rescue in my area and many wild hots end up getting in spots where the home owners freak out. I usually just relocate them to the wild life management area near me.
Snakes are not something to be feared, but they do demand respect. Some people though just blow my mind at how freaked out they get over snakes.
