I have no experience with using a pinkie-pump, have you? I ask because I've heard that they sometimes jam slightly with a bit of tissue or bone, and the risk is
a sudden release of pressure that can shoot the poor snake across the room (with obvious injury or death), so I've never tried or kept up on them at all...have
they made improvements? I've never had any such problems using the very smooth Gerber's chicken given by syringe...that's why I've always used that.
(And many years ago I tried to "blenderize" some pinkies/fuzzies but without a really GOOD commercial type blender, it's just not smooth enough.)
