You have not offended me in anyway, rest assured, it's just people have like your client make glib statements, I doubt the dog fighting, baiting type probably wouldn't have the brains or finance to keep the snake alive in the first place, let alone get it to the size that could take a kitten, small or not
Big snakes are dangerous, they can give you a nasty squeeze if they want, everyone I know who keeps snakes are incredibly knowledgable (more so than your average vet), about their snakes and are incredibly responsible, it's quite an achievement to create a rainforest in a 6ftx3ftx3ft tank which has artificial daylight, moonlight &star light, day temperatures and night temperatures and, too breed anyway, a seasonal difference in temperature and light length along with a constant 80% humidity.
We try and replicate natural feeding behaviours as well, so for example one of our arboreal boas (Brazilian rainbow boa- google it, they're amazing) has 5 chicks (dead & heated to blood temperature) 4 of which go in a heap in a 'nest' hollow up done wood, ones waved around on long tweezers, he has that and then goes off hunting for more, it is fascinating to watch, really amazing, and it's a natural behaviour
Oh and to give you an idea, that's a 7ft female Brazilian rainbow boa with a normal sized mouse, a 14ft retic only needs a guinea pig, if your squeamish the snakes just hugging the mouse in the picture, it's red light because they're nocturnal, so we use that if we want to see what's going on, the moonlight is very deep purple and not good for photos
