As with any species, some will feed well while others, for one reason or another, will not. However, mine all feed insanely well. My lereh tends to get overly excited at the smell of rodents which has resulted in her attack and constriction of various plants in her enclosure on more than one occasion (I have pictures of this somewhere on my comp). She has also been known to come completely off her perch and constrict the mouse and tongs. And my cyclopse x sorong male does his hunting pose every single night (and I'm sure he would eat if I let him) with his nose right up against the glass at any sign of movement. I'm pretty sure he's attempted to "stalk" my cats on more than one occasion. I think if you get an established yearling or older neo then you will have no problems with feeding.
