My cats spend part of their day locked up in the snake room (they're young and our backdoor is open for a chunk of the day for the dogs - we don't want them out yet, so they're confined). They don't care about the snakes and the snakes don't seem to know they exist. Of course ,they only ever see the snake ENCLOSURES and can not climb, on or see into, those. However, the snakes are out only when the cats are locked out of that room. Bottom line? I have no concerns for the cats safety, but I DO for the snakes. They're basically string that moves itself. I'd like them to stay free from claw and teeth marks -and alive.
As for latching onto as in a feeding response? Given how freaking finicky most BP are, I'm realllly not worried on that level. Forget the size. They don't smell like food. They smell like cats. Trying to get a BP to move from mice to rats is a typically a chore. Expecting them to randomly decide to eat a non-rodent is expecting a bit much of the feeding response of most of them. And unlike me/my hands, even, they NEVER smell of rodent.
