I would hope you are not SERIOUSLY suggesting to feed a rabbit to a BP
I don’t have any issue with feeder rabbits (for large snake) however for a BP this is way over-killed.
Because a BP can eat a large prey does not mean he needs to. Adults BP don’t require a large prey to thrive.
The largest I feed are small rats 65 grams once a week and it is enough food even for an adult, more than they would ever get in the wild.
