It is true that all snakes are different, and do react differently to different things. Since I've been feeding my two Kings and my Corn in their enclosures, they think I'm feeding them EVERY SINGLE TIME I OPEN THE CAGE so they spring out and try to get me on my finger. My larger King snake shows some serious feeding response.. just last week when I grabbed him to pick him up he almost bit my arm. And I know my arm looks nothing like his food. He's such a sweet snake.. but now he's showing some bad feeding responses.. My male BP and my boa do just fine with no feeding responses.
