I only skimmed it & one thing that article has wrong (for BPs especially) is that they say to offer food when your snake is cruising the cage. I say...BPs are ambush-
predators that prefer to lie in wait...when you see them peeking out of their hide box in the evening/night hours, that's the best time. Also, don't approach your snake
with the prey as that undermines the confidence of many a snake...wild rodents don't "volunteer" to be dinner.When using tongs to offer a f/t rodent (that is thawed
& properly warmed briefly) just give it a little motion (not too much) & make it appear to pass BY the snake within reach or just a little out of reach, & never approach it
directly. You want your snake to feel like it's chasing the prey & has the upper 'hand' with a surprise pounce. OK? Many here also use a blow-dryer on the rodents head,
right before offering, because BPs use their heat-sensing pits to find their acceptable target, not just vision.
When I kept BPs in the past, I converted them to f/t by feeding 2 smaller items that together were approximately the size of the one item they'd normally had. The first
was a live "appetizer" & I offered the f/t item as soon as they finished the first, & while they were still "pumped up". Usually this worked for me, but another way is to
'chain-feed' the f/t rodent, meaning you are right there (stealth helps so you don't distract the snake) and you feed the f/t into the snake's still-open mouth as he swallows the once he killed, nose to tail. If you do this right, they just keep swallowing the second (f/t) one. Either way, the idea is that they learn to accept the taste difference of f/t & after a few feedings this way, you can just offer f/t alone when they are hungry & usually they take it.
Another technique is to get some rodent droppings (some pet stores will give you some dirty bedding if you ask) & roll the f/t rodent in that prior to offering for a fresher
scent. Combined with the right temperature (blow-dried) this may also work.
BPs & all snakes have their own personalities & hang-ups. Your success in getting them to accept (much safer!) dead prey will depend on paying close attention for what
works best for your pet. Keep in mind that mice or rats with eyes closed do NOT bite back, but all those with eyes open DO bite in self-defense, & pose risk to your pet.
